LAUNCHXL2-RM46 Overview
1. (Optional) Installing Code Composer Studio (CCS)
The virtual COM port drivers that are required to see the console output of the out of box demo are bundled with CCS. If
you wish to see this part of the demo, install CCS v6.0.1 or later before connecting the LaunchPad to the PC.
2. Connecting to a Computer and Powering the LaunchPad
The LaunchPad is configured by default to be USB powered (JP6 must be installed), which can be done by connecting the
LaunchPad to a computer using the included USB cable. If you skipped the optional step 1, ignore any error/warning
messages about missing drivers during this step.
3. (Optional) Opening a Terminal Program
If you completed step 1 and wish to see the console output of the demo, this is the time to configure the terminal program of
your choice:
> Select COM port identified as "XDS Class Application/User UART" from your computer's device manager.
> Configure Baud Rate: 19200, Data Bits: 8, Stop Bits: 2 and Parity: None.
4. Running the Out-of-box Demo
This LaunchPad comes pre-programmed with a demo set that highlights several of MCU's safety features. When powered
the LaunchPad will start blinking USER LEDs.
Demo 1: An on-board Ambient Light Sensor is connected to the MCU's Analog Input 1. The USER LED B blinks according
to the light intensity and a change in light intensity will cause it to blink faster or slower.
Demo 2: Shorting jumper JP1 will short the OSC to GND and cause an Oscillator Fault in the MCU. The on-chip monitor
will detect and trigger an error singal causing the ERR LED to light up. Note: JP1 should be open during normal operation.
Demo 3: The push-button USER SWITCH B will inject a core compare error (CPU mismatch). An on-chip monitor will
detect the fault and trigger an error signal causing the ERR LED to light up.
Demo 4: The push-button USER SWITCH A will inject a single bit error in the MCU's flash on every push. ECC logic
corrects single bit errors in flash and counts them. The USER LED A blinks faster with every error detected. When a pre-
programmed limit (6) is reached, the error signal is triggered and the ERR LED lights up.
