RC_TX_nRF24L01_Telemetry_LED

It is a simple 5 channel RC transmitter for direct control of the nRF24L01 transceiver on the Arduino with ATmega328P for RC models. It contains the telemetry of the monitored RX voltage by means of a flashing LED indication.

Thanks to "Phil_G" http://www.singlechannel.co.uk for the calibration and reverse routine I used in the code.

This RC transmitter works with RC receiver from my repository RC_RX_nRF24L01_Telemetry_Motor_Driver_Servo

Function:

Calibration:

• Hold calibration button, switch transmitter TX on, still holding calibration button move all controls to extremes including auxilliary pots.
• Center all controls and aux pots.
• Release calibration button (saved to eeprom).

Servo reversing:

• To reverse the desired channel, hold the joystick in the end position and turn on the TX transmitter (saved to eeprom).

Arduino pins:

• A0 - pot 1
• A1 - pot 2
• A2 - pot 3
• A3 - pot 4
• A4 - pot 5

• D2 - LED
• D4 - calibration button
• A7 - input TX battery

nRF24L01:

• D9 - CE
• D10 - CSN
• D11 - MOSI
• D12 - MISO
• D13 - SCK
