# Reconfigure Powerblock pin usage - update



  • PowerBlock

    Re: Reconfigure [PowerBlock] pin usage?

    "No, it is not possible. Pins 11 and 12 are hard wired, sorry."

    Is this still the case?...

    ...Documentation regarding /etc/powerblockconfig.cfg states that the default(s) are pin 11 (GPIO 17) and pin 12 (GPIO 18) suggesting they can be changed.

    From Documentation:
    Configuration
    The configuration file of powerblock is located at /etc/powerblockconfig.cfg. It uses simple .ini file syntax = for setting the the values of its configuration parameters.
    The parameters are explained in detail in the following:
    • activated: Can be set to
    o 1: Activates the handling of the power switch signals of the PowerBlock.
    o 0: Deactivates the handling of the power switch signals of the PowerBlock.
    • statuspin: Raspberry BCM pin used for status signaling (default: 17) connects to S2 on PowerBlock
    • shutdownpin: Raspberry BCM pin used for shutdown signaling (default: 18) connects to S1 on Powerblock
    • logging: Enables or disables logging via syslog to /var/log/syslog. The logging is enabled if set to 1.

    My Setup:
    PROJECT SETUP

    Pi Model or other hardware: Raspberry Pi 3 Model B

    Power Supply used: ModMyPi AC Adapter Model GDJ-051025 5.1v 2.5a with On/Off Switch
    NOTE: Project will use RPI UPS Powerpack.

    RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): N/A
    Built From: N/A

    USB / Devices connected: Kuman I2S PiFi Digi DAC+ HiFi Digital Audio Sound Card, PIR and small Speakers

    Controller used: N/A

    Error messages received: Sound Card stops working - (I believe there is a conflict on pin12 = GPIO18)

    Log found in /dev/shm/runcommand.log (if relevant): N/A

    Guide used: (Mention if you followed a guide): N/A

    File: (File with issue - with FULL path): /etc/powerblockconfig.cfg

    Emulator: (Name of emulator - if applicable): N/A

    Attachment of config files: (PLEASE USE PASTEBIN.COM FOR LARGE LOGS): N/A

    How to replicate the problem: Attach PowerBlock and install service, then no sound.

    You could try and not connect the PowerBlock via the 2x6 pin header but connect the PowerBlock with jumper wires. You could then change the status and shutdown pins in the configuration accordingly.
