pigpiod startup problem #274

Closed gratefulfrog closed 1 year ago

gratefulfrog commented 1 year ago

Hello,

I've been using this library for sever weeks on an RPI4B+ with no issues whatsoever. It is really a great tool!

I am now trying to run it on an RPI3B+.

When I setup the pigpiod to startup automatically with sudo systemctl enable pigpiod it does startup but starts continually blinking certain gpio pins. In particular, the ones I need for my project... GPIO 17, 22, 23, 24, 27

If I run sudo systemctl stop pigpiod then restart, it works fine, the gpios stay at 0.

I am looking for at least a workaround, if possible, to be able to continue my project which requires fully automatic startup.

I am fully available to help debug this issue.

Thanks for any suggestion. Cheers, Bob

Hi Pi4J doesn't need pigpiod, so it should not be started at all... It uses pigpio which is included in the library itself.

Hello, Thank you for your reply! I am not sure that I understand. I have an RPI4 4Gbyte ram. Are yous aying I should not start the pigpiod at all?

I do not know what you mean by 'RPI4J' ? Does J refer to java? I only use the python interface.

But my problem today is getting it to work on the RPI3B+. Would you have any thoughts about that?

Ah, if you are you using Python and not a Java project with Pi4J, you are not using the correct GitHub project for your question... Better to try via https://abyz.me.uk/rpi/pigpio/
