I was wondering if anyone has hacked the audio input to the Sayso Globord to download messages to it for display.
I want to download messages for display from a PIC to the Globord. I believe the Globord takes an audio signal in for programming. I will have to convert the digital out of the PIC to analog.
Hopefully I will have enough resolution. I can do the programming my self but the problem is if anybody knows what the audio signal looks like. Different frequencies for different letters, duration of frequencies etc. Is it just like a digital code with 1kHz bursts etc?
If anybody has any knowledge it would be appriciated.
