Teensy 3.1/3.2 CPU Change Clock Speed

FAQ
1

Greetings all!
I have been using PlatformIO for just about everything since I found out about it, and loving it! My question is around the teensy31 board. In the Arduino IDE add-on for the Teensy, there is the ability to adjust the CPU clock speed. I was wondering if there is a similar option in PlatformiO?

Hope so, and thanks again,
–Chris

You need board_f_cpu :slight_smile:

Thanks very much!! Now I just need to figure out all the settings as they relate to the Arduino IDE options. But that’s MY problem.

Thanks again,
–Chris

found it in the documentation.
seems to work if copied to the platformio.ini file :grinning:

https://docs.platformio.org/en/latest/boards/teensy/teensy30.html

board_build.f_cpu = 48000000L
