Connect your Board & Run a Test Program

  • Run SimpleIDE.
  • Allow SimpleIDE to create a workspace (if prompted).
  • Connect your Propeller Activity Board or other Propeller board to your computer's USB port with a USB A to Mini-B cable or USB A to Micro-B cable.
  • Wait for your computer to detect and display a COM port for your board (upper right corner of SimpleIDE window).
  • If your Propeller board is not USB-powered, connect a power supply now. If your Propeller board has a power switch, turn it on.

3-position Switch
If your board has a 3-position switch, you can set it to 1 or 2. 1 will power the microcontroller and the sockets alongside the white breadboard. 2 will also power the 3-pin headers above the breadboard.

  • Click the Run with Terminal button, and verify that the "Hello!" message appears.
  • You should update your Learn folder to ensure you're using the most up-to-date libraries and code. Please go to Update Your Learn Folder for instructions on how to update.
