PlatformIO projects developed with LibreTiny can be flashed just like any other PIO project.
!!! abstract
All binary files generated by PlatformIO will be in .pio/build/<my_board>/. The methods described below may require you to get a file from that directory.
This path will be referred to as **build directory**.
LibreTiny has a built-in firmware uploader, based on ltchiptool. Pressing Upload in PlatformIO IDE does all the work for you.
If you have more than one COM port, configure your PIO project first:
[env:my_board]
monitor_port = COM96
upload_port = COM96{% include-markdown "../inc/uart-info.md" %}
{% include-markdown "../inc/uart-ltchiptool.md" %}
