Hey all. Thanks so much in advance for reading!
I am trying to get to where I can control 4 motors with two of the Dual FSESC6.6.
I am trying to use UART to connect to the first ESC, and then use the CAN bus to connect to the rest.
However, I know that this project is a bit advanced for me. My experience is that I have used UART to pull data from a GPS module, and written custom code to parse it.
I am trying to understand and use Benjamin Vedder's project for UART communication between a stm32discovery board and a VESC, and adapt it to an Rpi 3 b+.
It can be found here: https://github.com/vedderb/bldc_uart_comm_stm32f4_discovery
He (sort of) explains what you have to customize to port the code to another platform here:

The code I've used for UART so far was all adapted from the code on this page: https://raspberry-projects.com/pi/programming-in-c/uart-serial-port/usin...
Is there an explanation of how to do this that doesn't involve YOU having to teach me an entire class on programming? 
Thanks again. I know this is a sizeable project, and I really appreciate how willing you all are to help out people you don't know!
Hi @gabrielredding. Quite coincidentally, I am currently also trying to interface my VESC to an RPi. I have found the following projects on Github which supposedly perform the task that we are trying to achieve. I recommend you check them out. Let me know if you get any progress and I will do likewise.

Hello! Thanks for the response! I will check out those links and see what I can come up with. I did some extensive searching, and did not come across those, so I really appreciate it.
Any progress?
