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

[123JRM]

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.
