This sketch demonstrates how to easily transform a proportionnal RC channel into 5 digital commands with an ATtiny85.

COMMMAND OF 5 digital outputs from 5 push button replacing a potentiometer in the RC transmitter:
|
||||
================================================================================================
|
||||
Output pins: #1, #2, #3, #4, #5 of an ATtiny85 or a Digispark
|
||||
The receiver output channel is connected to pin#0 of an ATtiny85 or a Digispark
|
||||
A furtive pressure on the push button on the transmitter toggles the corresponding output on the ATtiny85 or a Digispark
|
||||
connected to the receiver output channel.
|
||||

Note:
|
||||
====
|
||||
- Decoupling capacitors are not drawn.
|
||||
- This sketch can easily be extended to 8 outputs by using an ATtiny84 which has more pins.
|
||||
- This sketch cannot work if you are using DigiUSB library as this one monopolizes the "pin change interrupt vector" (which is very time sensitive).
|
||||
- On the other side, its possible to communicate with exterior world by using <SoftSerial>, a library mainly derived from <SoftwareSerial>, but which
|
||||
allow to share the pin change interrupt vector through the <TinyPinChange> library.
