DIY - MSRC - Multi sensor telemetry for RC

This is a DIY project to send multiple sensors telemetry for a fraction of the weight and cost of the stock sensors using Arduino or Teensy boards. It adds support for several ESC protocols

Sensors:

• ESC
  - serial telemetry: Hobbywing V3/V4/V5, Kontronik, APD F/HV/UHV
  - PWM signal or phase sensor
  - Castle Link
• GPS serial (NMEA)
• Altitude/vario (BMP280)
• Analog sensors: voltage, temperature, current and air speed

Supported receiver protocols:

• Frsky Smartport : inverted serial, 57600 bps
• Frsky D : inverted serial, 9200 bps
• Spektrum SRXL V5: serial, 115200 bps
• Spektrum XBUS: I2C
• Flysky IBUS: serial, 115200 bps
• Futaba SBUS2: inverted serial, 100000 bps
• Multiplex Sensor Bus: serial, 38400 bps
• Jeti Ex Bus: serial 125000, 250000 bps
• Hitec: I2C

Supported boards:

• ATmega328P (Arduino Pro Mini)
• ATmega328PB (Pololu ATmega328PB)
• ATmega2560 (ATmega2560 Pro Mini)
• ATmega32U4 (Teensy 2)
• ARM CortexM0+ (Teensy LC)
• ARM CortexM4 (Teensy 3.2)
