The Adafruit cable is in the latter camp.
The first camp uses FTDI chips for TTL to USB conversion, the second camp uses PL2303HX chips. There are a wide variety of offerings for these types of cable. In this video, we use an Adafruit USB to TTL Serial Cable – Debug / Console Cable for Raspberry Pi. One of the nice things about the Jetson TX2 is that it uses 2.54mm headers, which make interfacing easy with the Raspberry Pi and Arduino ecosystems.
#USING TEENSY HARDWARE SERIAL LIBRARY SOFTWARE#
Other platforms and software programs can be used including Windows and Macintosh boxen. There are a wide range and variety of software terminal emulators out there, for this particular case the program Minicom was chosen. Installationīecause the Jetson communicates over a basic serial cable, almost any computer with serial terminal software can communicate with the Jetson. There is a nearly identical version of this post for the TX1, basically because we could not afford any new jokes for this article. Note: Because the Jetson TX1 and the Jetson TX2 use the same carrier board, the procedure is the same for both devices. Quite a handy thing to have when the going gets hardcore. UART 1 is the serial console on the Jetson TX2 which allows direct access to the serial and debug console.
Serial communication in the computer industry is ubiquitous, in this case we are going to connect an Ubuntu PC up to the Jetson TX2 Development Kit through UART 1 on the TX2 J21 GPIO header.
Apparently it was later rediscovered in America where teletypewriters used serial communication technology over telegraph wires, the first patents around stop/start method of synchronization over wires being granted around 1916. I’ve heard stories that Ferdinand Magellan first discovered a serial cable on his journeys, but lost it to a tangle in the battle of Mactan in 1521. The story of serial data transfer over wires goes back almost a hundred years. Here’s a simple approach for adding a serial console. A Serial Console is a useful tool for embedded development, remote access, and those times when the development kit has issues that you need to observe.
