①Receive CAN data<br />
②Display received data on the display<br />
③View data in real time<br />
I created the above program on Friday.After confirming that the program ran normally, I turned off the M5Stack.<br />
However, when I tried to check the operation of M5Stack again on Saturday morning, I could not receive CAN data.<br />
I decided that the newly rewritten program was bad, so I reverted to the program that was working properly before, but I still can't receive CAN data. Rewriting the previous program to another M5Stack worked fine. However, when I checked the operation again after an hour, both CAN data stopped being received.<br />
I'm having trouble finding the cause right now. The terminating resistor is 120Ω connected in parallel with the 120Ω of the commu module, and the combined resistance is 60Ω.<br />
If anyone knows the cause, please let me know.</p>
