I have redone the schematic.
I have checked for shorts, but nothing is obvious. I did run around with a knife to make sure, but that does not guarantee I got them all.
I am not real good with documenting my work etc.
I just plugged the regulator circuit into LTSpice, I think I am starting to see what the problem might be. Without the LED, I get an output of 5.2v at ~120mA. When I add the LED, voltage drops to 4.7v at ~80mA.
I have done the traditional Hello World with a blinking LED.
When it runs, it affects the power LED by dipping it.
I have the power LED after the 78L05 regulator with a 210ohm resistor.
Any ideas?
Appologies for the delay in responding.
I have been experimenting more, and found a couple of things out:
1) Do not slave the transmitter and receiver circuits to the same power supply
2) I have to send the command at least 3 times to ensure it is received.
As it is, it is working, but I am...
I have been searching the internet regarding some way of ensuring that the receiver gets the packets from the transmitter.
So far, it has been rather hit and miss. Sometimes it works, but generally it does not.
It has been suggested here and over at avrfreaks to use Manchester encoding...
