I would like to use a Picaxe to control a keypad on an IC-2200H radio. Basically
I want to add remote control to the radio thru the microphone Keypad. I ran across
all the specs here http://tinymicros.com/wiki/Icom_HM-98/HM-133_Internals
The microphone has 26 buttons that are arranged in a 9 X 4 matrix that control the
radio.
I am wondering if I can just use the picaxe and interface it directly to the keypad matrix
in the microphone to mimic the pressing of each button by useing 13 io pins of a picaxe.
The microphone dose send out a data stream from the cpu in it to the radio but it is not
a standard rs-232 asci format.
