Troubleshooting Penny K Pinball PKONE Hardware

If you got problems with your hardware platform we first recommend to read our troubleshooting guide. Here are some hardware platform specific steps:

Run Hardware Scan

Using mpf hardware scan you can find out if your PKONE boards are talking properly to MPF using USB:

$ mpf hardware scan

## Penny K Pinball Hardware

- Connected Controllers:
  -> PKONE EX2 USB connection - Port: com3 at 115200 baud (firmware v3.0, hardware rev 20)

- EX2 boards:
  -> Address ID: 0 (firmware v3.0, hardware rev 20)

- Switch boards:
  -> Address ID: 1 (firmware v3.0, hardware rev 20)

- Lightshow boards:
  -> Address ID: 2 (MIX firmware v3.0, hardware rev 20)

See mpf hardware (command-line utility) for details.

Enable Debugging

If you got problems with your platform try to enable debug first. As described in the general debugging section of our troubleshooting guide this is done by adding debug: true to your pkone config section:

pkone:
  debug: true

This will add a lot more debugging and might slow down MPF a bit. We recommend to disable/remove it after finishing debugging.

Startup and watchdog errors

MPF places a deadline on controller reset, board discovery, mixed LED configuration and initial switch snapshots. Check the first reported failure rather than repeatedly reconnecting:

  • A timeout usually means the wrong serial port, a missing board reply, a bad CAN cable or incorrect termination.
  • An address mismatch usually means duplicate DIP-switch addresses.
  • A malformed switch snapshot indicates incompatible firmware or corrupted serial/CAN traffic.
  • A hardware-watchdog timeout stops MPF because the boards have disabled their outputs. Correct the connection and restart MPF before testing again.
