Creating a New Target in BetaFlight
In this tutorial we will modify the BetaFlight source code to create a new hardware flight controller target. We want to add the Arduino Portenta H7 to the list of valid hardware targets. The Portenta uses the STM32H747XI dual Cortex®-M7+M4 32bit low power ARM MCU. This is quite a mouthful!
Despite their being two cores on the Portenta chip, at this stage we will only be looking at using one, the M7.
