I’m using RaspberryPI Zero W.
I’m trying to use spidev to control SPI with python.
I enabled SPI in config.txt, I installed spidev, I gave it permissions.
I believe SPI is properly enabled because
root@DietPi:/dev# lsmod | grep spi spidev 7220 118 spi_bcm2835 7456 0
root@DietPi:/dev# ls -la /dev/spi* crw-rw---- 1 root spi 153, 0 Apr 1 13:17 /dev/spidev0.0 crw-rw---- 1 root spi 153, 1 Apr 1 13:17 /dev/spidev0.1
When I try to run sample spidev script it does not report any problems.
Using scope I can only see CS line going down and then back up, MISO, MOSI and CSK lines show no activity.
Any ideas what am I missing?
