=================
14 July 2021
- Rebuilt with updated VM:
- 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.
- Added beep when a button is pressed, but only if none are pressed before.
- Increased allowable Modbus message length from 125 to 253 to allow more registers to be sent at once with the available buffer size.
- Added commands to implement indexed CRCs, whereby a user can run up to 5 CRC implementations at a time.
- Added hooks in all currently-used device types to run CRC calculations on all transmitted bytes.
- Added maths functions.
- CRC16 init value define added.
- Added utility function to check and convert numbers incorrectly converted by FloatMem16S.
- Updated source code for FloatMem16S to convert numbers correctly.
- Modified PWM driver code to cope with inverse outputs correctly.
- Modified STM32 F4 register allocation to allow PWM signals to be generated on the N outputs on port E.
- 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.
- boolean VM_oSPLatLinkConnectivity(void) function is added to splat_vm.c
- Changed checking of pin reset reason in resetInit function before checking standby.
- Updated SPX code for CPU.
- Modified System source files so their ARM_vCrash calls can be trapped.
- Added code to handle a Modbus ReadInputRegisters command, faking it to read the RAM.
- Added code also to read and write addresses in the 4000 range and the 5000 range, faking them as RAM locations.
- Modified order of reset condition testing so watchdog would have first priority.
- (System) Added magnitude checking when sending the LSB of an analog value over SEXI
- Also removed a warning from the VM LCD code.
- 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]
- System Update (STM32 F4 family): Extended GPIO map to include ports F,G and I, which are only available on the larger devices.
- System Update: Added STM32F405ZGT as a target processor (same includes as the 407)
- 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.
- (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.
- (System) Implemented signed version of byte-sized display routines (OBLCD_SDecDispMFW, OBLCD_SDecDispMVW, OBLCD_SDecDispXFW and OBLCD_SDecDispXVW)
- (System) Modified SPxPoll2 4,'C000 (Write to buffer location) to update the output immediately if it is changed.
- Changed order of LCD initialisation to ensure the buffer is cleared after the CGRAM is set.
- Moved 50us delay into LCD_vWriteByte to ensure every command includes an appropriate delay.
- SPLat/OS: Modified LCD driver code to minimise the chance of multiple threads writing to the LCD at the same time.
- Added code to implement OBLCD_GetCurYX
- Added 4KB Battery-Backed NVEM page 3
- SetCursor or SetCursorYX now outputs the new position to the display immediately if the cursor is on.
- Added framework code behind the SPiceX calls: SPiceConfigU, SPxTxfrU and SPxMode.
- 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.
- 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).
- (System) Increased U part of UV register array from 21 bytes to 251.
- System: Added new allowable baud rate value of 15626 (offset 13), specifically for the RFID device.
- (System/VM): Added new function to enable setting just the receive call-back function.
- SetCursor or SetCursorYX now outputs the new position to the display immediately if the cursor is on.
- Added framework code behind the SPiceX calls: SPiceConfigU, SPxTxfrU and SPxMode.
- Debugged OBCA code: The problem was that the SPLat code was mistakenly setting the mode to OFF.
- Modified registers for TIM8-12 to the correct polarity/enable settings.
- System Clarification: Changed OBCA Read command names to indicate Poll4 instead of the incorrect Poll1.
- Utils: Added 32-bit version of bit reversal code just to complete the set.
- 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).
- Also added macro paste commands to the utilities.
- Added PWM resynchronise function and a call thereto.
- STM32: created PWM measurement driver
- 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.
- 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.
- VM: added generic module for driving outputs as either analogue or digital
- VM: added support for OBLCD_HGraph, OBLCD_CursorOff, OBLCD_CursorOn, OBLCD_CursorBlink. These also work over Xwire, both as master and as slave.
- OS: ANALOGUE_OUTPUT now includes an INVERTPWM parameter, so fAnOut 0.0 means maximum.
- VM: comms profile 5 was 8bits, odd_parity, 2stop but should have been no_parity as per MODBUS standards
- SPLat/PC is now able to connect via TTL serial to ARM boards on the first attempt.
- 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.
- SPLatOS: AIO_oReadVref now returns a normalised value, unscaled as some boards may use 3.4V rather than 3.3.
- VM: relay driver can now invert the PWM signal, for those times it's connected to an inverting input.
- 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)
- ARM ST: added generic speaker driver for ST parts, this required a large structural change to the analogue output module (both PWM & DAC)
- VM: floatFromU was not working correctly for negative numbers.
- VM: OBLCD_Dim may now be used without throwing an error on boards that only support a virtual LCD, it is simply ignored.
- STM32F4: can now read the 3V3 rail
- 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.
- VM: ARM controllers now support UVtoNV for NVEM page 1 and up.
- 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.
- 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.
- 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.
- VM: stop I/O messages during app upload
- 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.
- VM: generic RAM module, WIP
- 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.
