The small code was just to test the timing and give the correct delayus that you need to have the module work. The program repeat the numbers from 0 to 20, testing the busy PIN. The important part is the diagram of the time to have it works. On the web we have many different version of the timing to...

Finaly WORKS!!!!, see the data timing diagram. The correct PIC basic is the following, count from 2 to 20 (0002.AD4 to 0020.AD4). Main: For J=2 To 20 xxx1: If BusyPin=1 Then GoTo xxx1 ' Verifico il PIN Busy, se alto attendo DelayMS 10 VoiceNumber=J GoSub PlayVoiceNumber Toggle Led DelayMS 35 Next J ...

Thanks for the information, I am still develop right now by PicBasic PRO. No C unfortunately. I am still develop a project for telemetry (hardware and software) of RC flight model, like Vario, Air speed, GPS, etc. I need to have a module speaking about altitude without have a LCD display or watch it...

Ciao, I have some difficult to have the module WTV020-SD16P works. It work manually (play next, previus, etc). When I try with a pic18F2620 I have no sound from the module. I thinks is a problem of timing, I have seen that you have made different versions of the timing on CLK, DATA e Reset PIN. I ha...
