hey, i am trying to make 2 8051 communicate using 2 rf rx, tx modules . The task is simple: i have to stop a motor when i receive a signal from the transmitter on the other 8051. Each 8051 has an rf rx and tx please help
fair enough, i know the theory of the micro controller but i have little knowledge of an rf module. if you could suggest some material on the rf module it would be helpful. im using a 434mhz transmitter receiver pair
And do you know the practice of how to apply it?
And the practice of designing & writing programs?
Again, have you managed to do this "locally" on a single microcontroller, using a switch as the signal to control the motor? There's no point getting bogged-down in RF before you have that done & understood.
"if you could suggest some material on the rf module"
When using any component, your first point of reference should always be the manufacturer's datasheet.

If the manufacturer can't (or won't) provide adequate documentation, then choose another manufacturer! (the price may be a little higher - but what's the point of a part that's cheap but unusable?!)
Also be sure to search the manufacturer's website for supporting materials - Application Notes, Examples, Development kits/boards, Tutorials, etc, etc,... Distributors may also have (additional) support materials...
Again, particularly as a beginner, the level of support should be a key consideration in selecting a product to use...
Then Google for examples of others using the same (or similar) modules...
(other internet search engines are available)
this was helpful. Thank you. Il post with more as it goes.
