TSM_PicoW_Blinky

Project using the Pico-W board with VS Code, implementing a simply blinky program. Note that this project requires the Pico SDK 1.5.1.

McuLib

The project uses the McuLib. The location of the library is specified with the variable 'MCULIB_DIR' in the top-level CMakeLists.txt. The McuLib can be shared with multiple projects.

Environment

In order for this project to work, the Rasperry Pi Pico SDK needs to be installed and shall have set two environment variables as below (example below for Windows):

PICO_SDK_PATH=C:\Raspy\pico\pico-sdk
PICO_TOOLCHAIN_PATH=C:\Raspy\arm-none-eabi-gcc-13.2.1-1.1\bin

Additionally, the launch config uses a variable pointing to the SEGGER installation, example below for Windows:

SEGGER_PATH=C:/Program Files/SEGGER/JLink

The variables can be set on user level.

If using OpenOCD, have a variable pointing to OpenOCD executable too, for example

OPENOCD_PATH=C:/OpenOCD/xpack-openocd-0.12.0-1-win32-x64/xpack-openocd-0.12.0-1/bin

Coverage with gcov

Install gcovr with

pip install gcovr

On Windows, it is possible that gets installed in a local environment, e.g. C:\Users<user name>\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.12_qbz5n2kfra8p0\LocalCache\local-packages\Python312\Scripts and gcovr.exe won't be found. Either use the path or copy gcovr.exe into a path which can be found.

For coverage, enable PL_CONFIG_USE_GCOV in platform.h.

To generate a text report:

gcovr .

To generate a HTML report (directory gcovr must exist):

gcovr --html-details -o ./gcovr/main.html

or use Terminal -> Run Task... -> gcovr

Unit Tests

Enable 'PL_CONFIG_USE_UNIT_TESTS' in platform.h

Run JRun manually:

"c:\Program Files\SEGGER\JLink\JRun.exe" --device RP2040_M0_0 -if SWD build/debug-test/TSM_PicoW_Blinky.elf
"c:\Program Files\SEGGER\JLink\JRun.exe" --device RP2040_M0_0 -if SWD --jlinkscriptfile test.JLinkScript build/debug-test/TSM_PicoW_Sensor.elf
"c:\Program Files\SEGGER\JLink\JRun.exe" --device RP2040_M0_0 -if SWD --rtt --jlinkscriptfile src\tests\test_1.JLinkScript build/debug-test/TSM_PicoW_Blinky.elf

Manual test run:

ctest -v --test-dir build/debug-test --timeout 15 --output-on-failure
