So im trying to send CAN frame from arduino to stm, im using mcp2515 module for it and it keeps sending this kind of frame, if i want to recieve CAN frame it works good but if i want to send one it doesnt work, any ideas?
Welcome, I do not have a clue what "stm" is. A better explanation of what you are trying to do would help. Also links to technical information on the hardware items helps a lot. Links to azon and similar sales outlets do not have enough technical information. What library are you using. When you send a CAN frame what acknowledges it?
I'm doing kinda the same thing (without dht) that is in this link but instead Arduino -> Arduino im trying to do it Arduino uno -> STM32F407, and if im doing STM32F407 -> arduino CAN bus communication it works and i can see the dataframe but when im trying to transmit data from arduino to stm32f407 like on this example it looks like on that screen and something causes error
