New Hoverboard Firmware Hack. Now written from scratch and generally much better.

hoverboard-firmware-hack

This is a Fork fom NiklasFauth's hoverboard-firmware-hack.

The goal is to make the board more configurable without requiring reprogramming for every setting, and to allow controller the board over different interfaces.

Current state:

• implemented dma/interrupt based UART2/3 RX/TX (see uart.h/c)
• implemented simple modbus slave (supports commands 0x3(read) and ox10(write). Works with open-source QtModMaster tool
• implemented modbus wrapper to allow user-defined variables to be accessed in code and over modbus.
• Built GUI to talk to modbus-wrapper and allow plotting/changing and storing device settings
• Added Tacho/Speed signals for both motors
• cleaned code from some hacks/features. Some will be re-added later
  • removed I2C/ADC/PWM control. This will be re-integrated soon
  • clean up BLDC ADC handler, now more efficient, and only dealing with motors
  • no more delays in code, but rather non-blocking Tick() based updates
  • disabled buzzer, man I hate buzzers
• implement flash-eeprom emulation to store settings in bvm memory

Coming soon:

• selectable control method. (Uart,I2C,ADC,PPM)

If you have any feature requests, open up an issue and I will get back to you a.s.a.p!

Working Processor swap to STM32 on YST-DXT-J20 V4 Motherboard : no motor control yet

Hello all,

I found lack of documentation for the Avery AT32F403 aggravating so I decided to buy an STM32F103 and swap it out on my YST board. I now use the PlatformIO system on Visual Studio and it works pretty good. I am using a fork this firmware located here https://github.com/bipropellant/bipropellant-hoverboard-firmware . I have a 3.3 volt serial connected to C9,B2 and that works too. I have ASCII control of the board. I also have the STlink connected for debug and that works as well. using the software ASCII console I am unable to rotate the motors and I think it relates to different drive circuitry on the YST boards. I have been intently comparing the various differences in the makefile looking for the area that addresses the motor control of the AT32 system that i will need to substitute in so that I have that in my ST32 firmware. I hope this makes sense. I am slowly coming up to speed with the code but so far I have been unable to find what I need. I see references to a current limiting system being controlled with a gpio pin on the new boards but i can not find that code either.
