I have 3 VESCs that I want to give individual different rpm commands over CAN BUS. Will it be better to use a mpu or mcu for this? Is there a particular library that I can use? Maybe for stm
Also what will the can connections look like? I have read that ground and 5V should not be connected. What is the reason for this?
And how do you carry over the CAN connection since VESC just has one CANH CANL set, will a pcb shield have to be made?
What is the suggested frequency for sending commands? and what bus load should you remain under?
