# RC-PWM-SPI

RC Receiver PWM to SPI for ATtiny / Digispark

Example SPI slave implementation

This code implements a simple SPI slave receiver interface

combined with multi-channel pulse-width modulation (PWM)

measurement. Each channel's pulse width is measured in

microseconds and returned in a channelized register interface.

This code can be useful for using a remote-control transmitter

to control an Arduino / ATtiny microcontroller.

- A watchdog timeout is used to detect the loss of the transmitter.

- Optimized IO commands are used in the ISRs to keep the

  critical sections as fast as possible.

- This example demonstrates 6 channel monitoring, but this can

  be increased/decreased if needed.
