It's necessary to place the GPIO in Device Tree to configure the GPIO to work in a mode of software SPI, I2C, for GPIO to be used as the source of the interrupt, etc. | |||
For example on a pin 10 @ UEXT1 (CS) and pins 5 @ UEXT2 (SCL), 6 @ UEXT2 (SDA), 10 @ UEXT2 (CS) | For example on a pin 10 @ UEXT1 (CS) and pins 5 @ UEXT2 (SCL), 6 @ UEXT2 (SDA), 10 @ UEXT2 (CS) GPIO processor lines are derived. They can be configured to use such as a chip-select for SPI or as I2C. |
