The frequency of the crystal.connected to your MCP2515.
If I set
And using these commands, the CAN frame can be received, and the bitrate is half of the rate being set to MCP2515, why is that?
Also, if I use this script, the device can’t be detected
I changed the setup_slcan to set the slcan0 bitrate to 125000, now The node can be detected, but I still have no clue why the bitrate is half of the speed being set in MCP2515
What is the frequency of the clock supplied to your MCP2515?
It is being set to 16MHZ
No, I am asking about the hardware configuration. The symptoms suggest that the clock is not actually 16 MHz. Can you measure it directly?
I can’t really measure the frequency, but I can give you the configuration being set to the registers.
These are the registers being set to CNF1 - CNF3
Try 250kBPS_8MHz, that should fix the frequency problem.
Thank you! Now it works.
I sure love looking at screenshots of code written by myself
