hi any one have AM radio emeter (simple) project or shematic and ducumentation for LPC ,processor thinks
Hi,
sorry my question is not fully understood, i write about AM EMETER , that is a radio transmitter or some kind of meter to measure am waves?
Regards
"my question is not fully understood"
A question can never be fully understood if you don't provide sufficient detail!
How do you propose that a transmitter will measure "AM waves" - don't you need a receiver for that?!
Or do you mean that it will "measure AM waves" and then transmit its results by radio?
Or what?
And what, precisely, will it measure? And over what range? etc, etc...
On a similar note, my 8052 has 100mA, Has anyone found or created a 2mW FM transmitter for 88-108 Mhz?
I'm looking to broadcast around the farm, would make it easier all around for me.
Hope this doesnt count as a hijack..

That may well be illegal without an appropriate licence - Check your local laws...
"Hope this doesnt count as a hijack"
It's all pretty off-topic - being nothing to do with Keil software tools...
Yes, a lot of people have managed to find low-power FM transmitters suitable for transmitting MP3 music to a car radio or similar.
FM transmitters powerful enough to span a farm would most probably be illegal all around the industrialized world, since such a transmitter would interfere with official broadcasts.
I have to assume your post to be a bit of a joke, since any 100mA power consumption or total port drive current or whatever is completely irrelevant to the power of an FM transmitter. A uC doesn't have the speed to modulate data at the normal FM radio frequencies...
