Reason for not supporting 10-bit i2c addressing

[AntonOellerer]

Hey,
Just out of interest, what is the reason for not supporting 10-bit addressing in i2c communication?
I looked around for a bit, but did not discover anything specific.
Best regards

Hey Anton. When RPPAL's I2C module was initially developed, 10-bit addressing wasn't supported by the underlying Linux drivers on any of the Raspberry Pi models available at the time. I haven't checked if this has changed recently, but you should be able to call set_addr_10bit, and it'll check if the underlying driver supports this feature.
