How to build

Open the project inside Visual Studio Code and select CMake: Build Target from the Command Palette (STRG + Shift + P). As alternative you can press Shift + F7.

How to run

Copy the program to the µMIC.200 controller by selecting Terminal -> Run Task... from the menu. Start the download by selecting Copy program. Open the terminal view in Visual Studio Code (CTRL + Shift + ´) and connect to the µMIC.200 controller.

ssh umic@umic.200
./digital-io

How to debug

Open the terminal view in Visual Studio Code (CTRL + Shift + ´) and connect to the µMIC.200 controller. Start the GDB server on the µMIC.200 controller.

ssh umic@umic.200
gdbserver :2345 ./digital-io

Select Debug -> Start Debugging from the menu or press F5. The debugger will start and set a breakpoint at the first code line of the program.
