CAN Rx Line between STM32 and MCP2561
Ok, Thank's guys, i'm so sorry it was due to a bad solder on my MCP2561 Gnd Pin.
On the TX Side, i'm facing a problem due to the ACK, i always encountered a timeout issue when i want to send a Can Frame :


And the frame is received multiples times on the other CAN Equipment : 
When i send one frame, the MCU seems to send multiples frames until it reach the timeout.
