[SOLVED] CAN communication between two STM32F103C8T6

[surendran_raj]

Hi everyone
I need to communicate between two STM32F103C8T6 microcontroller using CAN. First i made try to transmit and receive data in loopback mode it worked .Now i try to transmit and receive data between two STM32F103C8T6 controller in normalmode but i can't able to transmit and receive data. Can anyone help me to solve this problem.
Controller - STM32F103C8T6
CAN module - XL1050

Thanks in advance.
Surendran

Use a scope to check the tx and rx signals between the micro and the CAN transceiver.
Also check the CAN bus signals, Don't forget the CAN bus 120 ohm terminations. For a short test setup, a single 60 ohm resistor is OK.
The 'S' pin on the XL1050 should be grounded for normal operation.

Hi,

we don´t have good informations.
consider to post
* your code (both sides)
* a schemtic and/or wiring diagram
* a desription of the test setup
* what you expect to happen
* and what you see instead
