The ongoing development on 2.3.x is done in this branch.
Refer to the OpenTX wiki for information about setting up the tool chains for building OpenTX and OpenTX Companion as well as other development related issues.

Enable HAL (Haerdware Abstraction Layer for the STM32F407VET6 chip on the popular STM32F4VE development board. Where this is motivated for the following reasons:
- To have a cheap development platform to test on.
- To have a cheap alaternative to DIY radio platform. (Endless possibilities of design)
- To be able to add periferals as needed to test different connectivity - (Like 4in1, New radio protocol, sticks, ect... )
With in this brach, I hope to provide support for the following cheap LCD screens to see the OpenTX display.
