Question

To know about CAN communication between two STM boards.

Hello, I'm trying to communicate between two STM boards through CAN. I'm using STM32F103ZET6(as Transmitter) and STM32F103C8(as Receiver). I'm not getting the output,

can I get the code? or tell me the method to debug my code in STM32IDE.

Perhaps start with the wiring?

See Tiny CAN method described by Keil for a simple MCU to MCU connection using diodes rather than a transceiver. CAN expects to see feedback of CAN_TX on CAN_RX to know if it successfully driving the bus or conflicting with another controller.
