PokittoLib

Library for programming Pokitto hardware

How to Use

  1. Import this library to online compiler (see button "import" on the right hand side
  2. DO NOT import mbed-src anymore, a better version is now included inside PokittoLib
  3. Change My_settings.h according to your project
  4. Start coding!
