No problem! I was able to get this working The code provided was perfect - I just needed to wire up my MCP2551 correctly.

I'm assuming the DAC is not linear either? I was testing it and a voltage sent to the ADC from an external sensor was a bit higher than if the same value is sent through the DAC

Update. Now the driver calculates the baud rate prescaler based on the APB clock and I added a few more baud rates. (requires math.h) CAN_Init intCAN_init(){ //Time quantum double __tq = 0; //Bit timing float __bt = 1000/CAN_cfg.speed; //enable module SET_PERI_REG_MASK(DPORT_PERIP_CLK_EN_REG, DPORT...
