In a post on the NVIDIA Jetson TX1 forum, Wilkins White (Atrer) from Nova Dynamics (ww@novadynamics.com) wrote up a quite wonderful explanation of how to enable SPI on the Jetson TX1. The SPI interface is used in the discussion to interface with a MCP2515 CAN Bus Module (CAN Bus is Read more …
In the previous article on the LIDAR on a Chip, some folks asked if it is possible to run the chip outdoors. Looky here: This is just a short article on how the test was done. The LIDAR on a Chip in this article is a VL53L0X from ST Microelectronics. Read more …
ST Microelectronics recently introduced an inexpensive single chip time of flight sensor. The VL53L0X can be interfaced to a Jetson Development Kit (either TX1 or TK1) over I2C. Looky here: Background The last couple of years have seen a major push towards solid state LIDAR. As autonomous vehicles, robotics and Read more …
In some earlier articles, we installed the Bosch BNO055 on both the NVIDIA Jetson TK1 and Jetson TX1 development kits. However, the explanation for installation on the Jetson TK1 was a little too round about, even by the low bar we set around here. Therefore, here’s a more direct installation Read more …
Another couple of devices that will be needed for upcoming projects on the Jetson TX1 Development Kit are an IMU and a PWM driver for servo control. These devices can be interfaced over I2C. Looky here: Background We have covered using the Bosch IMU BNO055 under ROS and the PWM/Servo Read more …
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 …
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 …
LIDAR-Lite is a laser ranging module from Pulsed Light, Inc. which is a lightweight and cost effective measurement device. LIDAR-Lite can be accessed over I2C or PWM. The JetsonHacks Github repository contains a small library for accessing the LIDAR-Lite v2 over I2C. Looky here: The LIDAR-Lite v2 in the demo Read more …
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 …
Installing a 4 Character, 7 Segment LED that communicates with the NVIDIA Jetson TK1 over I2C is useful for adding a little visual flair to numeric display projects such clocks, up/down counters and numeric displays. Looky here: Background On a thread over on the NVIDIA Jetson TK1 Forum a forum Read more …
