No access to GPIO on Raspberry Pi 4 #38

Open IgnatiousPei opened 3 years ago

IgnatiousPei commented 3 years ago

I'm using the latest free version of FreeLSS as of writing: Version 1.22. I recently also updated the WiringPi library.

On my Raspberry Pi 4 the lasers don't toggle and the motor doesn't do anything and by using a multimeter I found that by toggling the lasers in software there is no change in the GPIO voltage, hence my conclusion.

If anyone has any suggestions please send them my way as I am absolutely stumped right now.

Same here, any answer?

Hello, I still can't get the motor to work as of writing this update, but the lasers decided to work after I updated the GPIO software. How to know if your GPIO is out of date? Type gpio readall on console and then if you don't get a table of readouts of all the pin values or it says "unknown board" or something like that then its definitely a GPIO problem. I recommend updating everything and rebooting.

Thankyou for the reply. I will keep trying, does it work on the PI3? Larry
