Need help with new SpeakJet
SN96
Posts: 318
I have attached a pdf of the circuit I am working with at the bottom.
I recently bought the SpeakJet and I am able to get it to work in demo· mode setting the jumpers M0 to V+ and M1 to V+ but when I set M0 to V- and M1 to V+ (Normal mode) the speak jets ready LED is on but when I try to run the example code, it does not do anything. I'm trying to figure out if my custom board design is at fault, or if I am doing something wrong with the serial interface. I have Pin 15 of the stamp going to the SPeakJet's RCX pin and Pin 14 of the stamp going to D2 of the SPeakJet.
Do I need to set the baud rate? Are my serial connections wrong? I am not using the DB9 connector, I want to use the stamp pins of the Homework Board.

I also used just the RCX line and removed the Rdy wire. Not sure why this worked but it did.

straight 9600 TTL by default. RS-232 has inverted logic levels but this isn't RS-232.
Using RS-232 on the SJ without some sort of level conversion chip (DS275 comes to mind)
will probaby kill your SJ RCX pin!!! If that happens you'll really be in bad shape.
Please note that the spec sheet for the SJ declares a NEED for a resistor attached to
the RST (Reset) pin for proper operation. The same thing applies to M0 & M1. I know
the diagrams for minimal connections in the spec sheet for demo'ing the SJ do not show
any resistors but that's intended for testing. PLEASE HEED THE DIRECTIONS IN THE TEXT.
SpeakJet schematics I've seen use resistors with a value of about 4.7K-ohms (YELLOW-VIOLET-RED).

I did not know that you needed a resistor for the reset pin as well as M0 & M1. I am going to revise my schematic to add resistors to these nets. Even though the SJ seems to work fine without them, I figure it's cheap insurance to add the resistors.

You betchya!!! Besides the spec' calls for 'em. Alas, they never say what value... :-|
If you've dealt with PIC processors before then keep in mind that the SpeakJet is really
just a preprogrammed PIC -- not some hotshot new piece of silicon. Pullups on the
event inputs would be considered a good thing too -- it keeps 'em from "floating".
Oh, it's been recommended that for Pin 4, place a small (~100-Ohms) resistor in series
with the pin to any input. Not necessary for operation but, since Pin 4 is the MCLR pin
(read "Master Clear") which is used when reprogramming PIC you probably don't want
some negative going spike to clear yer SpeakJet.
Have phun!

EEPROM of the SpeakJet. After that's been done use the MSA command to say GOTO PHRASE 'n'.
This boils down to sending two characters, a ASCII-29 followed by ASCII-n, where 0<= 'n' < 16.
So two characters to the SJ will get a phrase played. This phrase can 'call' or 'gosub' to another
phrase in EEPROM and come back to the previous phrase; upto 3-levels deep so you can chain
these critters.
It's easiest to use the 'PhraseALator' program to get your phrases setup. Otherwise, see
page 11 of the 7/2004 version** of the manual about writing phrases to EEPROM on the SJ.
Alas, I don't have any code but you might check the Files section of the SpeakJet group on
Yahoo -- there may be some code there.
Any questions, just gimme a holler.
** Sorry, I'm at work right now but I thought there was a newer manual around but I can't
find it. I could be wrong.

I will re-read the manual and see if I can get this going. I'll get with you if I can't get it to work.
