Project configuration

After base mbed project creation and configuration perform the following configuration to setup board:

1. Go to project root directory.
2. Run mbed add https://github.com/vznncv/TARGET_WEACT_H743VI.git to add this library to your project.
3. Copy custom_target.json from library folder to your project folder.
4. Run mbed target WEACT_H743VI command to set default board.
5. Run mbed toolchain GCC_ARM to set default toolchain.
6. Run mbed export ... command if you use IDE, as new files have been added to you project.

To program/debug you project, connect hardware debugger and optionally usb to serial adapter to pins PA_3, PA_2.

note: a serial adapter is requires only for printf/scanf functionality and tools that use it (like greentea tests).

Examples

Base examples can be found in the examples folder.
