The Texas Instruments Robotics System Learning Kit (TI-RSLK) had an online embedded programming course based on it. As of November 2023, it appears that Texas Instruments is no longer supporting the programming course, and all references to it appear to have been deleted from the ti.com website.
An alternate development environment is available by using Arduino and Franklin Cooper's Energia-RSLK-Library which provides easy to use functions to access the various peripherals that are part of the robot chassis. Combined with the multitasking capabilities ("Energia-MT", based on TI-RTOS) and available on the MSP432 processor, a sophisticated robot control sketch can be created.
This repo contains various example and testing programs that I have created while experimenting with the TI-RSLK.
All sketches include code to display messages and status information to an external NewHaven 2x16 OLED. The MSP432 controller used by the robot has 256KB flash memory and 64KB RAM, which is more than adequate to support the OLED library and text string storage, whether or not an actual display is used.
This example has the TI RSLK driving forward until it hits an object (i.e. a bump switch is triggered), then it stops.
The TI-RSLK follows a line on the floor using a simple (non-PID) algorithm.
The RSLK main board has connections to attach an LCD or OLED display to the robot chassis. The pins directly support SparkFun 10168, Adafruit 338, or Adafruit 938 displays. I don't have any of those displays, so I connected a NewHaven 2x16 OLED. Since the pin placement does not match, I created an adapter board that made use of the AF938 connector (which I use because it has a 5V supply pin). The pins are numbered 8 to 1 (left to right) when looking at the chassis from the top:
