We use GPIO to talk to external devices on the NVIDIA Jetson Nano. Looky here: Introduction One of the nice things about the Jetson Nano is that there is an expansion header which is useful for General Purpose Input Output (GPIO). You may have thought about turning a light on Read more …
The NVIDIA Jetson AGX Xavier GPIO Header Pinout table has been updated with the Linux GPIO numbering and work sheets mapping the Tegra pins all the way to the GPIO Expansion Header. Note: The table is kept on a separate web page for easier maintenance. There’s a lot of info Read more …
It is straightforward to connect an I2C device to a Jetson AGX Xavier. Looky here: Background I2C is a straightforward serial protocol. There are usually two wires, one is for transferring data (SDA), the other is a clock which is used to mark the begin and end of data packed Read more …
It is straightforward to connect an I2C device to a Jetson TX2. Looky here: Background I2C is a straightforward serial protocol. There are usually two wires, one is for transferring data (SDA), the other is a clock which is used to mark the begin and end of data packed (SCL). Read more …
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 …
