gpio-transmitter does not work

gpio-transmitter does not work on the RPi1. It work neither with the gpiod nor with the rpi-gpio backends. I tried:

  • sudo gpio-transmitter -B gpiod -L 10 -C /dev/gpiochip0 -f examples/gpio-play-test.log
  • sudo gpio-transmitter -B rpi-gpio -n 10 -f examples/gpio-play-test.log

But the following works OK (using gpioset from libgpiod v2.1): gpioset -t 100,100 SPI_MOSI=1
