anyone using SpeakJet ?

If you dont already have it, all the info you will need is in the data sheet:

http://www.magnevation.com/pdfs/speakjetusermanual.pdf

You can interface with the chip using serial communication from a PIC. SpeakJet's pin 10 (RCX) is a serial input (TTL). Connect your pic like this:

PIC I/O Pin --------+------- SpeakJet Pin 10
                    |
                   ---
                   | | 47k Resistor
                   | |
                   ---
                    |
                  Ground

You can use pbp's SEROUT routine to communicate with the chip.

The default baud rate for the SpeakJet chip is 9600, but can be changed. I dont see any need to deviate from the default tho.

I recommend your read the chips data sheet if you havnt already.

I have already read the data sheet many times and checked out some sample programs for other basic's. As I eluded to earlier, different people seem to hook it up differently.

Some ground all pins except the I/O, some try one of the methods of flow control. I am not getting good results with the few configurations that I have tried.

Have you actually used one? If so, how?

Mine sounds like it has turrets.

Just to make sure, I take it you have the following connections?

- pins 1-4, and pins 6-9 (E0-E7) connected to ground
- pin 5 (Gnd) connected to ground
- pin 10 (RCX) connected to the PIC I/O pin (and also grounded via 47k resistor)
- pin 11 (Rst) connected to +5v via a resistor
- pin 12 (M1) connected to +5v via a resistor
- pin 13 (M0) connected to ground
- pin 14 (V+) connected to +5v

*edit* if you have some code you are trying, post it and ill have a look

Yes, it works. I have tried this. See more at http://www.sapteka.net/pic16f877andspeakjet.htm
