The MAX7302 SCL line operates only as an input. A 4.7kΩ (typ) pullup resistor is required on SCL if there are multiple masters on the 2-wire inter- face, or if the master in a single-master system has an open-drain SCL output. Each transmission consists of a START condition (see...
E. g.: "gpioget $(gpiofind con1-11)" always finds the correct line to request the state of pin 11 of the connector. Of course only GPIO supported pins can be used, e. g. my device has way less pins capable of GPIO than the rock-pi. Therefore, con1-03 may be for rock-pi,...
