  • Prerequisite. You will need to have PlatformIO installed.
    • If you do not have PlatformIO installed
      • Download and install official Free Microsoft Visual Studio Code
      • PlatformIO IDE is built on top of VSCode

VSCode with PlatformIO

  • Initial Quick Check
    • Connect a Micro USB cable to Computer and IPEM Board
    • The IPEM board has bring-up code already on it - so you can just test.
    • Open a Serial Monitor
      • A quick option is ArduinoIDE, or load a project in PlatformIO and use this.
      • Baud rate defaults to 115200
      • Change Serial monitor Baud rate, if different.
    • Press board Reset
      • This should display various hardware information and default readings.
    • The board is now ready for quick voltage and current testing, if you wished to do it now
      • Press and hold USER button on board for ~ 1 second, to update Serial monitor readings
    • If you have an OLED Display connected, this will update too.
