GPIO Interfacing – NVIDIA Jetson TX1

December 29, 2015 9

Interfacing with the Jetson TX1 GPIO (General Purpose Input/Output) subsystem can be accomplished with a small “C” programming language library and knowledge of the J21 expansion header. Looky here: Background In a previous JetsonHacks article GPIO Interfacing – NVIDIA Jetson TK1, we covered how to interface with the Jetson TK1 Read more …

GPIO/I2C on Jetson TX1 – LIDAR-Lite v2 Installation

December 8, 2015 7

Interfacing with GPIO/I2C on the NVIDIA Jetson TX1 Development Kit is slightly different than it’s little brother, the Jetson TK1. This is mainly because the GPIO header is physically different on the Jetson TX1, which uses a 2.54mm IDC type of connector, similar to the physical connectors on Arduinos and Read more …

Ultrasonic Distance Sensor – HC-SR04 – NVIDIA Jetson TK1

October 29, 2015 9

Ultrasonic Distance Sensors, like the HC-SR04, are an inexpensive way to measure distance from the Jetson TK1. Looky here: Background Echo location is used by echolocating animals, such as bats and dolphins, for navigation and object detection. Echolocating animals emit calls out to the environment and listen to the echoes Read more …
