Re: Programming Arduino proc in Hilltopper-20

Hi Ted,
 
John is incorrect, the processor is an ATMEGA328 like you say, programmed via the Arduino environment.
 
The sketches are available via the Hilltopper groups.io reflector.
The easiest way to change the code in the chip would be to take the chip out of the radio and use an Arduino Uno with chip socket - some Unos use SMD processors, but a lot of the clones use DIP chips in a socket.
 
The Hilltopper chip will already have the bootloader on it, so once you've put it into an Uno, you can just upload the sketch via the Arduino IDE.
 
You could program the processor via J5, but you'd have to connect up the wires to an external programmer (or even an Arduino Uno).
 
If you join the Hilltopper group, you'll find more information.

Oh, I had a quick search and found this....
