Download SPLat Firmware<\/h6>\n\n\n\n<div class=\"wp-block-buttons is-horizontal is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-499968f5 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-text-align-center wp-element-button\" href=\"https:\/\/webprojects.cloud\/wordpress\/splatco\/wp-content\/uploads\/2025\/05\/ec1_release_v4-14.dfu\">dw2 V4.3<\/a><\/div>\n<\/div>\n\n\n\n<pre class=\"wp-block-code\"><code>=================\n== Version 4.3 ==\n=================\n03Aug2018\n- VM: comms profile 5 was 8bits, odd_parity, 2stop but should have been no_parity as per MODBUS standards\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- 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- STM32F3: can now measure the 3V3 rail based on an internal reference\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- VM: stop I\/O messages during app upload\n- DW2 demo, can now choose 485\/TTL when there's an Xwire error\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- VM: the delay between a slave receiving and replying was to quick causing legacy controllers to miss the response, increased to around 500us.\n- VM: Fixed InputOM that was returning wildly incorrect values.\n- VM: SPxChOut is no longer NULL terminated, allowing V to be any value without impacting the data in U.\n- ARM: fixed a reset that could occur if Xwire Slave was restarted when it &amp; 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: SPx callbacks modified to receive the registered address, this allow multiple instances to exist.\n- VM: floatFromU and fixToU were corrected to treat W as big endian when transferring between U\n- DW2: default SEXI app now supports address change on the fly and auto detect of TTL\/485 ports.\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- 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- VM: Doing a fGetTimer or Test quickly after starting a timer may sometimes have caused the timer to expire immediately.\n- DW2: switching channels wasn't throwing away the rubbish samples.\n- VM: WtoU, QtoU, UtoW, UtoQ, fixToU, floatFromU, would incorrectly error when loading a float into U&#91;16+]\n\n=================\n== Version 4.2 ==\n=================\n10 May 2016\n- First formal release \n- DW2: enabled EEPROM driver\n- DW2: V4.2; Now supports 2 ADC channels\n- VM: WaitOnKT wasn't working (incorrect opcode length)\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- 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\n=================\n== Version 4.0 ==\n=================\n10 Aug 2015\n- First release<\/code><\/pre>\n\n\n\n<h6 class=\"wp-block-heading\">2.
