i2c frequency orange pi zero


im trying to change the i2c frequency on the orange pi zero, how does one do this.
ive found the i2c_arm options in the config.txt haven’t tried them yet because im not sure what they do.
so what do they do.

Thanks in advance


config.txt only effects RPi boards. We leave this in for all images, simplifies coding, as we don’t require if checks on file locations each time we want to modify a shared item across multiple devices.

As for i2c frequency and changing this, no idea, sorry.

Would be good to find out as it is stuck at 100k - no reason not to go to 400k if we knew how
