# ppm_decode
PPM decoding for no_std rust. 
This library decodes the commonly-used PPM format used in radio control 
and other embedded applications. 


## Example

Typically PPM pulse input might be received via an input pin interrupt.
The important thing is that you provide this parser with the time
of the start of a pulse. In PPM the only time difference that 
matters is the difference between consecutive pulses. 

See `PpmParser` documentation for example usage,
or refer to the 
[test_ppm_decode](https://github.com/tstellanova/test_ppm_decode)
project for an example using an stm32f4 microcontroller.
