rf communication between two microcontrollers
hi all
i'm doing a project on controlling vehicle movement(simple car module) using touch screen
i'm sending states like whether the vehicle is moving forward, backward, left or right...depending upon the touch screen movement
it has got two parts... transmitter and receiver i'm using atmega32 controller both sides
transmitting and receiving parts are working fine when connected by wire
when i use rf module (standard 433MHz transmitter datasheet can be downloaded from www.sunrom.com) for transmitting data(state) serially i could not receive the states(1byte) properly may be because of noise.
i tried diff baud rate (4800,2400,1200,300 according to datasheet) but wen i see the output i'm getting junk values+transmitted states
rf module works fine(recieved data with almost 0 error) when the code contains only sending some data nothing else...in all the above mentioned baud rates
can some one help me how could i get the proper bytes using rf transmission so that it can be recieved with much less noise
it will be helpful if you post the diagrams,schematics...
