Hello,
We are setting up CAN communication between an MCU and the MPQ7225A LED driver:
At 500 kbps or lower: The LED driver responds normally with status and CRC.
At 1 Mbps or higher: There is no response at all.
What potential causes should I look into? Could PCB layout (artwork) be the main suspect, or should I re-evaluate physical layer factors like termination resistors and CAN signal integrity?
