Sampling Rf433 data

Projects Programming

Hi, Thank you for reading.

I'm trying code a RF data transmitting library (Not to re-invent the wheel, but to get hands on experience about Rf data transmission).

I'm using Attiny13s and RF 433Mhz transmitter and receivers.

My plan is to use at13s timer to sample the data, whenever the timer ticks, read analog data from the receiver. then i need to do some garbage filtering.

I have an issue timing receiver and transmitter. how to make sure timers on both AVRs tick at the same time.

Thank you.

You can't. They don't need to. They need to tick at the same rate, not the same time.

Within some tolerance / accuracy.
