Set up RTC for RGB LED Matrix Panel Drive Board For Raspberry Pi #1565

Open shinych opened 1 year ago

shinych commented 1 year ago

Hello (and sorry if I am asking in the wrong forum)

Is there any documentation or hints on how to set up RTC for that RGB LED Matrix Panel Drive Board from Electrodragon? Just putting the switch into RTC position does not work. Is there any driver or so?

You should probably ask the Electrodragon folks who sold it to you.

Thanks Henner for the prompt reply. And all your work.

The Electrodragon folks explicitly refer to "Please ask for support via github", refering to this project. https://w.electrodragon.com/w/RPI_RMP_Guide

Unfortunately I can find no more information on that.

There are a lot of tutorials if you search for "DS1307 RTC Raspberry Pi", e.g. https://www.instructables.com/Set-up-Real-Time-Clock-RTC-on-Raspberry-Pi/

The only thing I had to do additionally was to send a valid value to the RTC because the reading for seconds resulted in 0x80 which is not valid. Just type with installed i2c-tools: sudo i2cset -y 0 0x68 0x00
