MCP2515 SPI DRIVER DOWNLOAD

For example, I use 2msec delay after resetting it before attempting to communicate with the chip. Thus, when interrupt-driven SPI transmission is used in Master mode, and there exists a possibility that SS is driven low, the interrupt should always check that the MSTR bit is still set. Noam New Member Total Posts: Excellent, providing the oscilloscope traces. I can see what looks like capacitive coupling of the clock and maybe the data onto that received data line.

After the command byte is sent, the controller will return 8 bits of data that contain the status data. While that is possible, it is not the best practice, because it will take you time, but it is done in many situations even by professionals.
