Troubleshooting / Frequently Asked Questions

This page addresses bugs and issues that are commonly encountered when completing the lab exercises.

Left and right channels

If the operation of your program is not matching the expected behavior on the signal generator/oscilloscope, try swapping the left and right channels of the cables.

Managing multiple projects in the STM IDE

When importing the starter code for each lab, a new project is created with a new lab.c. By closing all inactive projects (right click -> close project), you can ensure that the correct source files will be used.

Desynchronized breakpoints

On rare occasions, the STM IDE will desynchronize certain breakpoints in debug mode. This can cause your code to stop at a particular line even after the breakpoint is removed. If this occurs, the safest way to resynchronize the debugger is by creating a new project.
