<\/pre>\n\n\n\n
=================\n== Version 4.9 ==\n=================\n14 July 2021\n- Rebuilt with updated VM:\n   - Modified I2C EEPROM clock line configuration for F3 and F4 processors from open-drain with no pull-up to push-pull, as we do not use a multi-master configuration in any product.\n   - Added beep when a button is pressed, but only if none are pressed before.\n   - Increased allowable Modbus message length from 125 to 253 to allow more registers to be sent at once with the available buffer size.\n   - Added commands to implement indexed CRCs, whereby a user can run up to 5 CRC implementations at a time.\n   - Added hooks in all currently-used device types to run CRC calculations on all transmitted bytes.\n   - Added maths functions.\n   - CRC16 init value define added.\n   - Added utility function to check and convert numbers incorrectly converted by FloatMem16S.\n   - Updated source code for FloatMem16S to convert numbers correctly.\n   - Modified PWM driver code to cope with inverse outputs correctly.\n   - Modified STM32 F4 register allocation to allow PWM signals to be generated on the N outputs on port E.\n   - Turned off VBUS sensing code as it doesn't seem to affect normal operations and allows the VBUS pin to be used for other things.\n   - boolean VM_oSPLatLinkConnectivity(void) function is added to splat_vm.c\n   - Changed checking of pin reset reason in resetInit function before checking standby.\n   - Updated SPX code for CPU.\n   - Modified System source files so their ARM_vCrash calls can be trapped.\n   - Added code to handle a Modbus ReadInputRegisters command, faking it to read the RAM.\n   - Added code also to read and write addresses in the 4000 range and the 5000 range, faking them as RAM locations.\n   - Modified order of reset condition testing so watchdog would have first priority.\n   - (System) Added magnitude checking when sending the LSB of an analog value over SEXI\n   - Also removed a warning from the VM LCD code.\n   - Added SPxChOut instruction to generate a CRC16. Load U with the data, V with the length, then issue a CPU SPxChOut command with code 0 for 16 bits and 1 for 24 bits.  Results start at U[1]\n   - System Update (STM32 F4 family): Extended GPIO map to include ports F,G and I, which are only available on the larger devices.\n   - System Update: Added STM32F405ZGT as a target processor (same includes as the 407)\n   - Changed 256-instruction limit to be 1024 instructions, as the 32-bit code is about 10 times faster than the 8-bit code where this limitation was introduced.\n   - (System LCD Driver) Corrected order of returned values from GetCurYX poll so that the correct Y value would be returned.  For some reason, the compiler swaps bytes 2 and 0 of the assignment.\n   - (System) Implemented signed version of byte-sized display routines (OBLCD_SDecDispMFW, OBLCD_SDecDispMVW, OBLCD_SDecDispXFW and OBLCD_SDecDispXVW)\n   - (System) Modified SPxPoll2 4,'C000 (Write to buffer location) to update the output immediately if it is changed.\n   - Changed order of LCD initialisation to ensure the buffer is cleared after the CGRAM is set.\n   - Moved 50us delay into LCD_vWriteByte to ensure every command includes an appropriate delay.\n   - SPLat\/OS: Modified LCD driver code to minimise the chance of multiple threads writing to the LCD at the same time.\n   - Added code to implement OBLCD_GetCurYX\n   - Added 4KB Battery-Backed NVEM page 3\n   - SetCursor or SetCursorYX now outputs the new position to the display immediately if the cursor is on.\n   - Added framework code behind the SPiceX calls: SPiceConfigU, SPxTxfrU and SPxMode.\n   - Added SPxCmd2 command to write a byte to a specified LCD buffer location. Command format is SPxCmd2 2,address with U[0]=offset and U[1]=byte.\n   - Added SPxPoll1 function to LCD VM so it could: - Read a character from the LCD buffer at a nominated position; - Read the current brightness (also available via the CPU).\n   - (System) Increased U part of UV register array from 21 bytes to 251.\n   - System: Added new allowable baud rate value of 15626 (offset 13), specifically for the RFID device.\n   - (System\/VM): Added new function to enable setting just the receive call-back function.\n   - SetCursor or SetCursorYX now outputs the new position to the display immediately if the cursor is on.\n   - Added framework code behind the SPiceX calls: SPiceConfigU, SPxTxfrU and SPxMode.\n   - Debugged OBCA code: The problem was that the SPLat code was mistakenly setting the mode to OFF.\n   - Modified registers for TIM8-12 to the correct polarity\/enable settings.\n   - System Clarification: Changed OBCA Read command names to indicate Poll4 instead of the incorrect Poll1.\n   - Utils: Added 32-bit version of bit reversal code just to complete the set.\n   - Added SPxPoll1 function to LCD VM so it could:\n      - Read a character from the LCD buffer at a nominated position;\n      - Read the current brightness (also available via the CPU).\n   - Also added macro paste commands to the utilities.\n   - Added PWM resynchronise function and a call thereto.\n   - STM32: created PWM measurement driver\n   - VM: If the first output in a call to OutputM didn't exist the controller would correctly reset but incorrectly not report the error to SPLat\/PC.\n   - VM: UVtoNV wasn't working right as it was ignoring the \"offset\", so now modified for use in ARM meaning V must be explicitly set, it won't use NVRecLen to allow for a more flexible instruction.\n   - VM: added generic module for driving outputs as either analogue or digital\n   - VM: added support for OBLCD_HGraph, OBLCD_CursorOff, OBLCD_CursorOn, OBLCD_CursorBlink.  These also work over Xwire, both as master and as slave.\n   - OS: ANALOGUE_OUTPUT now includes an INVERTPWM parameter, so fAnOut 0.0 means maximum.\n   - VM: comms profile 5 was 8bits, odd_parity, 2stop but should have been no_parity as per MODBUS standards\n   - SPLat\/PC is now able to connect via TTL serial to ARM boards on the first attempt.\n   - The STM32F4 I2C EEPROM driver had an edge case where sometimes it wouldn't send a NAK when reading from NVEM1, this meant the EEPROM sometimes held the SDA line low and caused the F4 to flag a BUSY condition & reset the VM.\n   - SPLatOS: AIO_oReadVref now returns a normalised value, unscaled as some boards may use 3.4V rather than 3.3.\n   - VM: relay driver can now invert the PWM signal, for those times it's connected to an inverting input.\n   - VM: reading the internal analogue reference via a float (ie in the VM) now returns a normalised number based on the ST factory calibration value (multiply by 3.3 to get Vcc)\n   - ARM ST: added generic speaker driver for ST parts, this required a large structural change to the analogue output module (both PWM & DAC)\n   - VM: floatFromU was not working correctly for negative numbers.\n   - VM: OBLCD_Dim may now be used without throwing an error on boards that only support a virtual LCD, it is simply ignored.\n   - STM32F4: can now read the 3V3 rail\n   - VM: A race condition existed in the QuadratureCounter that could cause wrong readings to be returned, often this was seen when moving backwards with the count being returned as a large positive number rather than a small negative number.  Thanks to Michael B for spotting this.\n   - VM: ARM controllers now support UVtoNV for NVEM page 1 and up.\n   - VM: ARM based OBQC_fGet used to return 0 thru 16777215, but this meant moving backward from 0 would cause a jump to 16777215.  So now it returns negative, which is the same as 8bit SPLat controllers.\n   - VM: YieldTask may now be called in single tasking mode without throwing en error.  This is especially useful in subroutines which may be shared by both single and multi-tasking applications.\n   - Setting the NV pointer no longer checks for OOB, it now only check to ensure the pointer is < 0xFFFF.  This means the PTR can be set and page chosen in any order.  The check for NVOOB is done only when reading\/writing NVEM.\n   - VM: stop I\/O messages during app upload\n   - ARMF4: tweaked NVEM1 EEPROM driver following field reports of unreliability.  Esp for reading, it will now try a few times to address the chip and will report read failures.\n   - VM: generic RAM module, WIP\n   - VM: Oh dear, RTCDateToUV, RTCDMToUV, RTCHHMMToUV, RTCHHMMSSToUV were all incorrectly using the _current_time_ rather than the values in the RTC registers.  So functions like OBLCD_HHMMSS were displaying the current time rather than the time in the RTC registers.\n\n\n=================\n== Version 4.8 ==\n=================\ndt16_1408_release_v4-8\n11 August 2017\n- VM: the delay between a slave receiving and replying was to quick causing legacy controllers to miss the response, increased to around 500us.\n- DT16: default SEXI app now supports address change on the fly and auto detect of TTL\/485 ports.\n- DT16, SEXI app timeout increased to 1 second\n- VM: Fixed InputOM that was returning wildly incorrect values.\n- NVEM may now report SPxNoResp instead of NVEMPtrOOB if there's a problem communicating with an external EEPROM\n- Xwire: the Xwire slave thread could run out of stack and cause a reset\n- ARM: fixed a reset that could occur if Xwire Slave was restarted when it & MODBUS Slave were operating simultaneously.\n- ARM: WarmBoot now doesn't cause an error, it just restarts the VM.  This is the same behaviour as the 8bit controllers.\n- ARM: SEXI was incorrectly calculating the output size limit, so a value of 37 outputs which is legal was throwing a \"too big\" error.\n- VM: floatFromU and fixToU were corrected to treat W as big endian when transferring between U\n- ARM STMicro boards: If MODBUS was set to 8 data bits even parity, a 0x00 would cause a LIN break and resulted in the packet being dumped resulting MODBUS errors (typically no response if the SPLat is a MODBUS slave).\n- VM: sometimes a controller running MODBUS would reset when SPLat\/PC connected due to an incorrect method of mutex release when closing the MODBUS port.\n- ARM: a 16bit and 24bit ID is now available on all ARM boards.  These are a CRC of a bigger ID so there's a small chance two controllers may have the same ID (chance is obviously less with the 24bit version).\n- SPLatVM: MemToUV and UVToMem were ignoring the u[n] offset and always starting from u[0].\n\n=================\n== Version 4.7 ==\n=================\ndt16_1408_release_v4-7\n12 Sep 2016\n- VM: fixed a serious bug in fSTTimeSince & STTest that 2 days after the controller is turned on made both functions think the elapsed time is always greater than 167772.16s.\n- ARM: The SPLat\/VM on ARM boards was throwing a RAM OutOfBounds error when trying to access byte 250 which is actually the legal last address.\n\n=================\n== Version 4.6 ==\n=================\ndt16_1408_release_v4-6\n16 Aug 2016\n- DT16: production test now uses HMI430\n- VM: Doing a fGetTimer or Test quickly after starting a timer may sometimes have caused the timer to expire immediately.\n- VM: WtoU, QtoU, UtoW, UtoQ, fixToU, floatFromU, would incorrectly error when loading a float into U[16+]\n- VM: WaitOnKT wasn't working (incorrect opcode length)\n- OS: OBLCD now returns a SeqCount whenever the buffer has changed so the caller can refresh only when necessary.\n- VM: GoIfInOn\/Off\/K were ignoring \"J\"\n\n=================\n== Version 4.5 ==\n=================\n11 Apr 2016\n- VM: Fixed STTest which was not working correctly due to a typo.  It was especially worse with small delays.\n- VM: NVReadRec & NVWriteRec were incorrectly expecting a 16 bit address but it's only an 8 bit address.\n- OS: STM32F4 devices now increase the nof analogue samples\/clock to increase accuracy\n- VM: A change to detect duplicated slave entries in the Xwire table was preventing correct parsing of the table, meaning slaves often weren't being added to the I\/O map.\n- OS: Saw the 1 second timer getting delayed, manifested by ComTestStartTimer taking 13 seconds dignal rather than 10.  Due to timers being deleted before the next timer was fetched.\n- VM: ComTestStartTimer now using fast tick to avoid expiring after 9 - 10 seconds (only following RUN from SPLat\/PC, power on was always 10s).\n- VM: XwireGetPollCntr now increments as soon as a packet is received rather than at the start of sending the response, this also fixed a problem where poll count was not incrementing if the slave had no data to return; interpacket time delays have been shortend to increase throughput.\n- DT16: new SEXI app with twice the performance.  Requires firmware 4.5.\n- VM: Fixed display of PermStore values in the \"Module\" window in SPLat\/PC as all bytes were off by 1, thus the first byte was always missing and the \"status\" was never correct.\n- VM: the Xwire LCD master now sends zeroes for the command bytes (blink, etc) otherwise sending these bytes sent garbage and stuffed up the LCD.\n- VM: SEXI was not working when analogue I\/O didn't start at 0\n- VM: now able to report analogue I\/O when numbering doesn't start at 0\n- SPLatVM: SEXI was not turning off blinking outputs when SPLat\/PC connected\n- SEXI: a duplicate slave entry in the Xwire table now doesn't incorrectly increase the nof I\/O's;\n- VM: More than 10 analogues, in or out, are now correctly sent to SPLat\/PC.\n- VM: Now ensure countdown timers are cleared on VM reset\n\n=================\n== Version 4.4 ==\n=================\n21 Aug 2015\n- DC216, DT16, DA8 now all support USB\n- VM: loss of SPLat\/PC will now stop I\/O update messages from being sent.\n- VM: SEXI was not receiving any _additional_ buffer from the slave device.\n- VM: draft of support for OBCB instructions\n- STM32F4 boards: fixed a crash that would sometimes occur when connecting SPLat\/PC.  Due to CCM-RAM not being initialised and nVM_vDeregistered() trying to kill a bogus thread pointer.\n- VM: fixes to Xwire slave LCD, esp when LCD isn't 20x4.\n- VM: An ARM based controller running as an Xwire slave can now display LCD text broadcast from a Master Xwire controller.\n- VM: A SPLatLink \"Get\" was returning 1 byte less than it should.\n\n=================\n== Version 4.3 ==\n=================\n03 Jul 2015\n- DT16: CPU is now secured and the user application can't be read out via JTAG\n- SPLatVM: Fixed \"Not\" which was converting 0 to 1 but should have been and is now converting it to 255.  This bring ARM boards in line with HC08 boards.\n- OS: If, for example, EP0 requested a 16byte response, some EP0 functions were sending 8 + 8 + 0 which is wrong as was causing the STM32F4 to send the zero length packet as parts of the response to the next request.\n- ARM: fGoIfPos was getting confused by a -0.0, changed it and fGoIfNeg to use the signbit macro.\n- VM: A recent fix for Xwire caused a regression in Xwire Master that caused it to access a NULL func ptr for XwirePhys when starting Xwire.\n- fixed a regression in _iiPrintXXX when printing to RAM where the printing would begin at the second byte.\n- Xwire: XwirePhys can now be done before starting Xwire\n- ARM: STM32 serial port lines weren't being correctly configured, the DR8 Xwire & RS485 ports weren't working; Changing interface no longer resets the port, it now just notifies the app and let's it do whatever it needs to.\n- SEXI: All digital I\/O's have been compacted so there are no unused lines.  This means the Xwire table is now actual number of I\/O's rather than blocks of 8.\n- ARM VM: Permstore was not being correctly erased on program download and instead was returning a status of \"success\" but with all 0 bytes.\n- The SEXI protocol could incorrectly report multiple InputK's as it wasn't confirming a change in sequence number from the slave.\n- ARM: ComRunScript can now be called anytime to change MODBUS master scripts.  The current transaction will finish before the new script starts.\n- fixed MODBUS slave output protection (was using RAM values)\n- ARM controllers now support MODBUS master\n- ARM Controllers: Dialect is now 101 for Countdown timer support\n- SEXI: after 8 tries, a disconnected peripheral will have it's reported inputs set to 0\n- ARM dialect now supports legacy timers:\n   The next ARM dialect, 101, will include support for the \"legacy timers\", aka:\n   Start\n   Stop\n   Test\n   fSetTimer\n   fGetTimer\n   SetTimer\n- ARM: The maximum Xwire message is now 64 bytes rather than 32 bytes.  This has been done to allow the DA8 to work as a SEXI device as it needs 35 bytes.\n- added MODBUS query attempts\n- fixed fWtoIEEE and fIEEEtoW in ARM based controllers\n- Xwire slave was crashing badly, a NULL pointer access.\n\n=================\n== Version 4.2 ==\n=================\n12 Sep 2014\n- First formal release.<\/code><\/pre>\n\n\n\n
