Derrived from CC18 firmware V3-16. Does not have the high speed counter peripheral.\n*\n* V3-10 18\/6\/2010 Abitrary string communications protocol added. This protocol allows the user to create and send ASCII\n* and binary strings and receive and parse same. Simple 8 bit addition and subtraction, both with and without carry\n* instructions have been added. The carry\/borrow bit for these instruction is held in the R register. Non destructive \n* floating bit compare and go instructions have been added. Bug fixed which prevented the BranchM instruction from\n* being jindexed.\n*\n* V3-11 10\/5\/2011 Bug fixed in arbitary string protocol where the buffer pointers were not re-initialised if there\n* was a program error and the program re-started. RtoX instruction added. Bug fixed in the COMTX_Space instruction which \n* would return the number of bytes in the buffer rather that the number of free bytes. Bug fixed in Xwire slave sequencer,\n* other minor Xwire improvements to improve robustness in the slave mode when there are inadvertantly two Xwire masters on\n* the bus. Xwire TX and RX state machines now re-initialise themselves immediately that they are disabled. This\n* has been done to prevent unwanted beaviour when there are multiple slaves with the same address on the Xwire bus (PKS).\n* A bug has been fixed in the SPI module which may cause expansion I\/O to be ignored depending on the power up data contents\n* of the shift registers. Xwire modified to include a new comms error counter which is incremented to a maximum of 255 on\n* UART errors or parsing errors to allow communications errors, specifically collisions, to be detectable in addition\n* to the existing \"no response\" error counter (GetXwireErrCount). A new instruction called \"GetXwireComErr\" returns\n* the number of UART and parsing errors in X and clears the counter to zero. The OpCode for this new instruction is\n* $F5 $38. This is different to the existing \"XwireGetErrCount\" instruction which is incremented only on missed polls\n* but provides no information about collisions and corruptions being the reason for the lost poll response. \n* MODBUS\/SPLat\/String protocol UART RX interrupt routine and UART interrupt vectors modified to recover \n* correctly from UART overrun errors. Bug fixed in MODBUS which would cause the 3.5 character delay timer not to be \n* initialised if the selected baud rate was the same as the current baud rate. Xwire RX interrupt routine and UART\n* interrupt vectors also modified to recover from overrun errors. MODBUS code modified to always return idle status\n* when re-initialised. \n* Added 10 new floating point compare instructions which set X either true of false depending on the floating point \n* comparison. They are non destructive to W and Q. \n* Added \"COMRX_fGetNum\" instruction to string comms protocol to allow the extraction of numbers from the ASCII \n* string contained in the receive buffer. The routine will parse both signed integer and signed decimal numbers and return \n* with the result in W. The SPLat result register R will be zero if a number was successfully parsed or 1 if a valid number\n* could not be parsed. \n* Thermistor drive voltage is initialised to ON on the HD8, when the board is powered up or reset. Previously it was\n* initialised OFF.\n* Reports dialect 26.\n*\n* V3-12 23\/5\/2011 Added COMRX_StrFind and iiPrintNVText instructions. Bugs fixed in iiPrintFill and COMRX_peek instructions.\n* Changed buffer arrangements for the LCD driver and string comms protocol so that the string comms protocol can send \n* strings of up to 255 characters from a single string comms instruction. Previously, a limit of 40 characters applied \n* to the iiPrintText, iiPrintFill and iiPrintNVText instructions. Also, if the TX buffer was full when any String \n* protocol instruction which resulted in characters being appended to the TX buffer, an error would be generated and the \n* SPLat program reset. The user was expected to use the COMTX_Space instruction to ensure this did not happen. Now, the \n* TX buffer can be written at any time with the caveat that if the buffer becomes full during the execution of the string \n* comms instruction, the entire SPLat program will be stalled until the currently executing instruction can deposit all of \n* its characters into the TX buffer. The TX buffer is 128 characters in length. When the destination is the user RAM, the\n* instructions still execute atomically providing the string fits within the user RAM. If not, an error is generated and\n* the SPLat program is reset. Reports dialect 27.\n*\n* V3-13\t\t19\/7\/2012 Bug fixed which would cause the HD8 to run SPLat programs slightly slower than it should as it was always trying\n* to service the LCD hardware driver, which does not exist. New TextXY series of instructions added, board is now dialect 28.\n* Bug fixed in LCD formatter. Latest version of the arbitrary string protocol included with new instructions added. Included\n* latest Xwire driver with several bug fixes and the ability to send display data to controllers with an LCD. To allow the\n* latest features to be included, SPLat program\/NVEM space has been reduced from 26,112 bytes down to 22,016 bytes.\n*\n* V3-14 5\/3\/2014 Various module upgrades: FixMem instructions now preserve W, OBCBsetup instruction re-instated, LCD can now load\n* CG RAM from NVEM, MODBUS bug fixed.\n*\n* V3-15 6\/2\/2015 Added new instructions BlinkM, InputM and InputKM. Fixed a bug in caused by SPLatPC that would cause the UART profile\n* to be incorrectly set when changing back to SPLatLink comms. Added COM_flags instruction to user string comms.\n*<\/code><\/pre>\n\n\n\n2. Download SPLat reFlash<\/h6>\n\n\n\n
