PPM_to_USB_Joystick_STM32

An adapter to convert PPM RC signal to a Joystick - so it can be recognised by simulators (FMS, RCPhoenix etc.) A median filter shall reduce effect of potential jitter/outlier values for RC channels. 5-point median filtering is used.

Based on the following:

• Maple Mini CPU module (https://stm32duinoforum.com/forum/wiki_subdomain/index_title_Maple_Mini.html)
• Arduino for STM32 (https://github.com/rogerclarkmelbourne/Arduino_STM32)
• PPM Reader library for STM32 from FlyByWire (https://github.com/i998/FlyByWire)
• USB Composite library (https://github.com/arpruss/USBComposite_stm32f1)

Connection:

Connect a PPM signal to pin 2 (PB2).

Note - input signal is 5v max. Or use a resistor and a diode as a signal converter to 3.3v as described in the documentation.
