Gpiod- crl
WebJul 18, 2024 · Workaround: The workaround is to reboot the RPi4, perform the /dev/i2c-1 operations, then perform the gpiod operations, and to refrain from using /dev/i2c-1 until after the next reboot. A better workaround to somehow reset libgpiod would be great. Solutions: Use gpiod only and create a bit-bang I2C implementation on top of gpiod. Web\$\begingroup\$ I think the question is a bit different. The question is why can't you run at 72MHz when connected to the USB. USB usually runs from a PLL that is clocked from …
