+
+ 09/05/19 itoa() now working
+ 09/05/19_E Nextion now running at 115200 Baud
+ 13/05/19_D Ported over to Nucleo-F746ZG
+ 15/05/19_A First version working on Mbed Studio
+ 15/05/19_F Nextion RX Interrupt message decoder started
+ 16/05/19_A Increment / Decrement arrow work but project need to be cleaned up before going further
+ 16/05/19_A Push & Pop functions for touch buttons are working.
+ 17/05/19_A Adding debugging functions
+ 17/05/19_A Created a debug thread seems to work ok
+ 17/05/19_B Success Nextion slider is working
+ 17/05/19_B Flow rate / RPM selection now working
+ 17/05/19_C PWM now working, needs scaling factors to represent 100% for 1250 RPM etc
+ 17/05/19_C Progress bar working
+ 20/05/19_A Peripheral Pin List added
+ 20/05/19_D PWM frequency changed to 24kHz, this was found to be the frequency used on the DRV8306EVM BLDC Demo board
+ 20/05/19_D BLDC Motor working under PWM control, now reaches the same build level as QAD with Mbed
+ 28/05/19_A STM32 does not have any EEPROM, need EEPROM for NVM capability, adding EEPROM capabilities to project
+ 28/05/19_A Add digital motor control
+ 28/05/19_A Motor direction control working, other I/O need to be done when schematics arrive from TI
+ 28/05/19_B Nextion back light dim now working, it is fussy about where it is executed
+ 29/05/19_B EEPROM testing thread proves EEPROM can be accessed and read correctly, removing EEPROM result in all 00, with EEPROM pattern is repeatable.
+ 29/05/19_E Good demo code for NVM, needs tidying up
+ 30/05/19_A Can read full NVM, can write single bytes to NVM
+ 30/05/19_B This EEPROM library cannot write a single byte to a memory location, it does not work, you have to write the entire NVM which is not good
+ 31/05/19_A Other EEPROM library no good, will try this again
+ 31/05/19_A now working in a way to develop the NVM feature properly, this will be pursued after my holiday
+ 10/06/19_A Continue with NVM development
+ 10/06/19_B NVM ready for Nextion menu to be taken to next level to feature NVM settings
+ 12/06/19_A Rotation arrow on menu was not controlling motor rotation, it had been broken by adding other menu buttons, and this is something I am aware of now and to watch out for
+ 13/06/19_B Culled the amount of project in Mbed Studio as this was too big for the resources for Mbed Studio causing it to not recognize the target as an Mbed enabled device
+ 13/06/19_B Though I could get away with doing the NVM update in the RX ISR but this causes a run time error crashing the processor, I will place the NVM update in a thread
+ 14/06/19_A This code is broken trying to transition to better way to implement metering units selection, use next code or previous code
+ 14/06/19_C Taken most of the day but now NVM RAM is being written to from EEPROM, due to char* pointer this mechanism not working as thought, I have a working method now.
+ 17/06/18_A First implementation of working NVM, needs some refinement
+ 17/06/19_D Good refinement achieved for Metering Units NVM
+ 17/06/19_E memcpy() replaces for loop, implemented free() to free up dynamically created pointer memory after use as eepro.read() uses malloc()
+ 27/06/19_A Pre work ONLY for 4-20mA, setup of button membrane, 4-20mA control inputs
+ 01/07/19_A Pre work ONLY for 4-20mA, Open Drain outputs setup and default to off at power up
+ 02/07/19_A Adding map function
+ 12/07/19_A Assigned new I/O for start/stop buttons and start/stop LEDS as I/O I has assigned might be required later on as they are part of USB and ST_LINK stuff.
+ 15/07/19_A Grey Box build all working correctly, phew
+ 15/07/19_A Need to implement start / stop button control, added state machine
+ 15/07/19_A Motor thread commented out, motor control part of state machine
+ 15/07/19_B Not sure how text box b2 is displaying RPM when stopped, I have overridden this for now
+ 15/07/19_C Stop/Start operational
+ 16/07/19_A Scaling for RPM, ml/min and % working perfectly
+ 16/07/19_A_TEXT This is the first version that uses TEXT for displaying metering digits using printf
+ 17/07/19_C Issues with nextion, this version look ok
+ 18/07/19_A Page component IDs definitions had changed on Nextion HMI code again when I created 16/07/19_A_TEXT version, its a really crappy and stops your working code from working
+ 19/07/19_A 3 Second Watchdog implemented and working
+ 19/07/19_A Nextion power control added and working
+ 19/07/19_A 1ms timer implemented and working, not uses at present
+ 22/07/19_A Fit 4-20mA Module and connect up to system
+ 22/07/19_A DAC pins already use I will have to re-assign pins to be able to use DAC
+ 22/07/19_A ADC is now measuring mV, ADC is 12bit so more noise than 10bit ADC
+ 23/07/19_B 4-20mA is outputting to debug screen and is scaled using mapF, look fairly stable and no averaging has been applied yet.
+ 24/07/19_A Look at ways to make analogue reading more stable
+ 24/07/19_A Speed control using LoopMate achieved, although values from ain.read_u16() do not seem to make any sense at this time, was expecting 0 - 4095?
+ 25/07/19_A Good results displayed on debug screen without any software smoothing applied.
+ 25/07/19_B Working really well now I have add the moving average algorithm, this adds a nice ramp rate to the product
+ 26/07/19_A Full motor speed does not seem to be there, need to fix this and create a function for motor control via 4-20mA
+ 26/07/19_A Motor speed is ok now, used mapF() to make sure motor has stopped at 4.0mA, previously it would only stop at 0.0mA
+ 26/07/19_A Wow, showing excellent stability at 10uA resolution
+ 26/07/19_A Metering unit displayed against mA, cool
+ 29/07/19_A Rough ramp rate applied when change of motor direction, this code is only an experiment and is blocking and needs to be refined in to non-blocking code
+ 01/08/19_A Create functions for manual and 4-20mA
+ 01/08/19_A Nextion definition need changing for updated display GUI featuring QDOS type menu system
+ 02/08/19_A Created Timers.cpp to hold all timer functions and structures
+ 05/08/19_A Trying to implement manual control with dual speed inc/dec functionality
+ 05/08/19_A I have inc/dec functionality working, tidy code up and move forward
+ 05/08/19_C meter val changed to int16_t data type from uint16_t so abs() can be used for zeroing negative numbers
+ 05/08/19_C Nextion screen initializes on page 33 wher no buttons are, page 1 is called when start button is press, stop button calls page 33
+ 06/08/19_A Threads remove until required, all processing done in main and nextion RX ISR, all working.
+ 07/08/19_A Can now display flow units retrieval from NVM

+ 08/08/19_B Flow unit can be written and read from EEPROM
+ 08/08/19_C Implement manual and analogue operating mode stored in EEPROM
+ 12/08/19_A Analogue function need to support all flow units
+ 12/08/19_C This version can demo flow units change, analogue and manual mode selected from menu system
+ 12/08/19_D meterVal, minScale, maxScale are now floats to give resolution required, this version is not full working at this time
+ 13/08/19_A displayed info in p1left not correct, need to implement incDecSpeed variable so when the touch key is held the inc/dec speed increases
+ 14/08/19_A Beware EEPROM value had somehow been changed for run.mode stopping normal program from running, suspect power glitch, as a consequence
+ it has taken all morning to figure out the problem.
+ 14/08/19_B System can now be re-booted by pressing and holding down the ON button for 3 seconds
+ 15/08/19_A Add some diagnostics to check EEPROM contents
+ 16/08/19_A Change state machine structure so meter screen is correctly updated on return from Nextion pages
+ 27/08/19_B Inc/Dec indexer needs improvement
+ 28/08/19_B Inc/Dec control has been improved, speed can be set manually some tweaking may still be required at later point, moving on to analogue out now.
+ 28/08/19_C Start of DAC implementation to provide analogue output
+ 28/08/19_C SPI moved from SPI1 on CN7 to SPI14 on CN9, this is required to allow connection to DACs required for analogue output
+ 28/08/19_C I have verified that the SPI NVM is working after moving to other microcontroller pins for SPI14
+ 28/08/19_C I am able to set analogue output currents for test purposes.
+ 28/08/19_E Analogue output development started

+ 12/09/19_A Floats can be written to and read from EEPROM for mA high, flow high, mA low, flow low calibrations
+ 12/09/19_B % / mA graph working as initial demo
+ 16/09/19_A Calibration graph line generation now done on Nextion by timer so no resources are required for this micro.

+ 23/09/19_B USB ISOLATOR TO BE USED FROM NOW ON TO STOP USB GND EFFECTING THE UNIT
+ 23/09/19_B Calibration is working, checking all aspects of calibration
+ 24/09/19_A anaOut_mA(mapF(ana_mA, I_3MA, I_20MA, nvm.mA_low, nvm.mA_high)); APPEARS TO BE WORKING NOW, TESTING REQUIRED
+ 25/09/19_B Calibarion, analogue output, displayed flow units all appear to be match well to QDOS
+ 26/09/19_B Works like QDOS for calibration now and analogue in/out, issue when leaving calibration normal running does not resume correctly
+ 27/09/19_A Calibration graph has refresh problem when adjusting flow rate %
+ 30/09/19_A I hope the issue above in now fixed, this was done by erasing the RED line before going to the next calibration screen
+ 30/09/19_B Start looking at speed feedback from tacho output on motor controller
+ 30/09/19_B Tacko from fGout processed by isr test working
+ 01/10/19_A General code tidy, removal of unused variables, add ISR module
+ 03/10/19_A Implement motor stall detection
+ 07/10/19_A Motor development put on hold as present motor controller cannot produce high torque at low speed as QDOS 20 does
+ 07/10/19_A Remote Start / Stop implemented
+ 07/10/19_A Remote Fluid Recover, reverses motor in analogue mode, will check more when we receive new QDOS with this feature

+ 21/10/19_A Auto-Restart, remote inputs and O/C outputs working, read for checking with QDOS 30
+ 22/10/19_A Motor rotation is CCW but QDOS arrow is CW, Neptune will be set the same
+ 22/10/19_A FastPWM library added, leave PWM prescaler at 1 so that that the smallest speed inc/dec results in a measureable PWM change,
+ resolution is 12 bit (4096), measured bit width is ~20ns/bit, pwm period is 1/10000 = 100us, so 100us / 20ns = 5000

+ 30/10/19_B QDOS 30 flow units added to replace QDOS 20 flow units
+ 31/10/19_A Removed ramNVM so epprom data is transferred to and from direct to NVM data structure
+ 01/11/19_A NVM memory working good and more easy to understand and use now
+ 01/11/19_B PWM is now incremented / decremented at 0.1 resolution, so a change of 0.1% alter the PWM
+ 01/11/19_B Cannot find any problems with this version, best version so far
