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- ARMF3: volatile in typedef was placing constants in the .data segment, moved volatile keyword to variables themselves.\n- SPLatVM: MemToUV and UVToMem were ignoring the u&#91;n] offset and always starting from u&#91;0].\n\n=================\n== Version 4.5 ==\n=================\ndr8_1409_release_v4-5\n12 Sep 2016\n- VM: fixed a serious bug in fSTTimeSince &amp; 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 4.4 ==\n=================\ndr8_1409_release_v4-4\n08 Jun 2016\n- DR8: new SEXI app with twice the performance.  Requires firmware 4.4.\n- DR8: added full production test\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&#91;16+]\n- VM: WaitOnKT wasn't working (incorrect opcode length)\n- OS: Created IO_UNUSED() macro\n- VM: Created a generic conductivity module.\n- VM: GoIfInOn\/Off\/K were ignoring \"J\"\n- VM: Fixed STTest which was not working correctly due to a typo.  It was especially worse with small delays.\n- VM: NVReadRec &amp; NVWriteRec were incorrectly expecting a 16 bit address but it's only an 8 bit address.\n- STM32F3: EEPROM driver is working\n- DR8: NVEM1 is now available; now using generic bi-LED driver\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- 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- OS: analogue output number is now contigous as there would have been problem if a DAC was in the middle of PWM\n- VM: now able to report analogue I\/O when numbering doesn't start at 0\n- VM: low speed digital (OBCB) counting now works on ARM controllers.\n- SPLatVM: SEXI was not turning off blinking outputs when SPLat\/PC connected\n- VM: More than 10 analogues, in or out, are now correctly sent to SPLat\/PC.\n- DR8: Adjust COM port assignment, now TTL is 251, 485 is 252 and USB is 253\n- VM: Now ensure countdown timers are cleared on VM reset\n- VM: loss of SPLat\/PC will now stop I\/O update messages from being sent.\n- VM: now able to have a dout plugin without a read function\n- VM: SEXI was not receiving any _additional_ buffer from the slave device.\n- VM: Analogue output PWM frequencies can now only be set for outputs exposed to the VM\n- OS: New functionality allows timers to each have a different default PWM frequency\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- 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- SEXI: can now handle 64 analogue inputs (that's 8 DA8's!)\n- ARM: fGoIfPos was getting confused by a -0.0, changed it and fGoIfNeg to use the signbit macro.\n- ARM: Fixed error in SEXI that was preventing analogue output value to be sent to the slave.\n- VM: Xwire error counters were only incrementing in debug builds; Xwire was not incrementing the error counter if the received packet's length was wrong.\n- VM SEXI:a bug occurred when slaves did not have inputs in multiples of 8 and this would cause inputs from one slave to overwrite inputs from another.\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\n=================\n== Version 4.3 ==\n=================\n24 Mar 2015\n- ARM: STM32 serial port lines weren't being correctly configured, the DR8 Xwire &amp; 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- SPLat VM ARM:Any button press will now automatically turn on the backlight even if InputK isn't called.\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.<\/code><\/pre>\n\n\n\n<h6 class=\"wp-block-heading\">2.
