Interfacing Directly with the GPIO Peripheral on TX1 and TX2


On the RaspberryPi’s there is a few libraries like pigpio and WiringPI hat interface directly with the GPIO peripherals by writing directly to the register addresses.

This is particularly useful for hardware based I2C and PWM, where the clock cycle is directly managed by the chip crystals and not by the OS itself.

Is there any library like this for TX1 and/or TX2?

Short of a library, does anyone know where I can find the datasheet for the ARM chip on TX1 or TX2? I have been looking around online, but I have not find anything that has registry addresses.

For the RaspberryPi it is not terribly difficult to find the Broadcom chip’s datasheet.

there’s GitHub - NVIDIA/jetson-gpio: A Python library that enables the use of Jetson's GPIOs for your reference.
