Arduino-RC-6CH-Radio-control

FS-CT6B		HK-T6A

Arduino project to upgrade cheap Hobbyking HK-T6A or Flysky FS-CT6B transmitters or any other old RC TX

This code is based on ardutx v1.3 sketch (2014) from Patricio Reinoso www.patolin.com

The code has been modified to work with SH1106 SPI 1.3" or SSD1306 SPI 0.96" OLED LCD through U8g2 library

Have been used all possible pins of ATmega328P (Arduino Nano, Pro Mini)

Every text strings has been stored in flash memory to mantain a lot of free RAM memory

Added features to original Patolin code:

• 3 digital buttons input for menu (Enter/Select) (Down/Next) (Up/Previous) [previously analogs]

• Switches checking status with sound alert at power ON and display which is not in default position

• Throttle warning with display status of switches and sound alert

• Hidden data default restoring by pressing and hold Down/Next button on power on

• Hidden calibration procedure by pressing and hold Menu/Select button on power on

• Low battery control in real time whith buzzer sound(buzzer with stand alone sound generator)

• N°2 supplementary switch, they can be configured instead of VRA or VRB pots (SWA, SWB)(Servo Direction Menu)

• Basic two channel mixer with switch activation V-Mix (Ch1/ch2)

• Basic four channels Sub Trim setting (ch1, ch2, ch3, ch4)

Recommended Arduino Arduino IDE 1.8.2 or above
(Seems to be optimized and stable compiler. Less Flash and RAM used)
