Hi,
First, sorry for bad english, i'm french
I started my hyperion project some month ago and it didn't work. Forgot it, and now i'm retrying to make it work.
I followed this basic tutorial with a small led stripe (54 leds) : https://hyperion-project.org/t…mbilight-no-soldering.77/
Some leds light up when i plug the AC adaptor, with or without raspeberry..
I tested the SPI (loopback), tried another raspberry (tried with pi 3b and pi 0W)
I tested a HCT125 level shifter..
So i decided to go back to the basic and installed a fresh rasbian, this library https://github.com/tinue/apa102-pi and same results: some led light up, but no control.
With a friend we decided to measure tension in the led stripe and i don't know if this is normal:
Without wiring CI and DI to the PI (only power) we measured approx 4.2V on the CI band, one every two. and 0V on the other one. Does anyone know if it is this the normal way the led stripe work?
Do you have another idea i can test?
Thank you
