Hello we have to realize a project under MBED.
For this purpose, we have a NUCLEO-F446RE card.
We have already managed to communicate in SPI connection and read on the PC but currently we are blocking on the CAN connection.
We have a system that sends frames and has been validated as well as a module to transform CAN LOW and CAN HIGH into TX and RX using an MCP2551 module. This system has been tested and we are sure it works since we can display the output frames on an oscilloscope. However, we want to display on the PC using our NUCLEO and a program under MBED but our display does not work. We use the example program suggested by MBED in its CAN function via the mbed library.
We also looked at the oscilloscope at the output of our board and noticed that the TX influences the RX. Is that normal? Because this seems unlikely to us.
Are there any basic things to know that are not explicit and that block our program?
We have tried to do some tests but we are currently blocking.
Also, we are French so please forgive our approximate English.
Thanks for your answer.
