Related Config File Sections:

In your log you will probably find a line such as:

OSError: Error in WriteData: wrote 0 of 8 bytes

This error occurs when pinproc (the library MPF uses to talk to the P/P3-Roc) reports an error while talking to the P/P3-Roc via USB. This is most likely a bad cable or a power supply issue. See Troubleshooting P-Roc/P3-Roc for potential causes and solutions.
