In fact, it is the following idea: ...

0 background The Jetson TX1, TX2, AGX Xavier and Nano development boards contain a 40 pin GPIO connector, similar to the 40 pin connector in Raspberry Pi. NV officially gives a GPIO library, which is a Python version, and   The RPi.GPIO Library of Raspberry Pi is the same. This paper introduces the content and usage of the library. 1 ins ...

preface Channels is a type safe message queue. It acts as a pipeline between two goroutines, through which any resources will be exchanged synchronously. chan's ability to control goroutines interaction creates a Go synchronization mechanism. When the created chan has no capacity, it is called an unbuffered channel. Conversely, a chan crea ...
