You can use 208 or you can convert to hex(0xd0)
Good Luck
208 doesn’t work. I tried 201-208, 208-210 last night.
I tried everything. If I had another BAP, I could swap them out and see if that would solve the problem but all I have is this one.
It’s something to do with the serial data, but I am not sure if it is a timing issue or not.
What version of the IDE are you using? I tested the baud rates upto 230400bps on 8.0.1.3.
Also remember BAP inverted is the same as Stamp non-inverted(eg we are reveresed from them). Also the baudmode value has no resemblence to the Stamp number. We use different bits all together to indicate the bitrate and the othere states(inverted,parity,open or driven etc…). Thats why we have the constants(i9600 for inverted 8n1 and n9600 for non-inverted 8n1). The “i” modes are for use with things like PCs with max232 circuits. The “n” modes are for direct connections to other devices/chips without an inverter circuit.
I am using 8.0.1.3.
How about a small program that shows the problem and a datasheet(link) for the device you are trying to talk to?
Scroll down to the bottom for the link to the SpeakJet manual
Here’s the code I’m using. It has been converted to work with the BAP: (This code has been tested on the Basic Stamp II)

Here is the link to the full data sheet:
Ok so decsribe what happens. Does the beep sound? If so do any of the other commands run? Have you tried changing the code to not use flow control(eg send a couple commands you know won’t over flow the buffer) to see if you can get it working at all first. From the manual I do beleive n9600 is the correct baudmode but it is a little confusing. If you can connect the speakjet to a PC serial port through a max232 then you should be using i9600. Also note that the BAP has almost no delay between bytes being sent compared to a BS2. I see nothing in the datasheet saying the speakjet needs any delay between characters(there is no electrical characteristics in the datasheet) but it may so you should try adding a delay between each byte sent(eg see the pace argument for serout).
I have tried sending shorter data to the SJ to see if it would work without overflowing the buffer and it did not work. I also tried sending preset commands to cause the SJ to sound stored sounds, for example a beep.
When the BAP sends data to the SJ, in this case the number 262, it should generate a beep, instead it generates a distorted sound.
In an older version, I was able to get the BAP to send commands and it generated speech and sounds without any problems except flow controll. For the flow control problem, I used the delay feature that forced the BAP to pause X amount of time before moving to the next serout command. This worked fine but now it does not seem to work at all any more.
It might be possible there is something wrong with the BAP however, it moves a servo fine.
EDIT
I just rehooked everything to the BS2 and it works without any problems. I have no idea wht it works with one and not the other?
Hi Mike,
Not sure if I could add anything here, but have you tried different pins? Also I am assuming that the speakerjet gets its power from the connections from the BAP. So I am assuming you have the jumpers set properly and the TX line is on P2 and the RDY line is on P0…
Have you tried pausing before you do the output? I know when I try to use an LCD’s, I need to give them some time to initialize before I output to them.
It would be interesting to see the serial output of the simple beep on an oscilloscope for both the BAP and the BS2 to see the differences. If I get a chance, I might try hooking up my very limited Parallax USB scope and see what I see. Recently I was not able to make my LCD work reliably at 9600 baud on my BRAT, but that was with HSERVO enabled as well as some other interrupt code running. If I have some more time, I might dig through my box of stuff and pull out the BS2 and try to scope the same and compare the two. But right now I should get back to working on the revisions to our house plans…
I have tried all pins available on the bot board with no luck. I thought about checking the outputs on an 'O Scope also, but I don’t have one.
There is one thing I need to try: If I remember correctly, When I had it working before without the flow control fix, I used a seperate power supply for the speak jet board. The Bot board used 9v and the SJ used a seperate 9v supply and it worked. Perhaps using a shared power supply is my problem. I will post my results later today.
EDIT
I tried using a seperate power supply and it did not help any. I’m all out of ideas.
Hi Mike,
I had a few minutes and so I dug out my old parallax BOE board with a bs2 on it and tried converting the code…
I don’t have the speakerjet, so I can only look at the generated wave forms.
Something like:
[code]TX CON 2
RDY CON 0
LOW 0
main:
HIGH 0
SEROUT TX ,$0054,[262] ';Sound BEEP
LOW 0
PAUSE 100
GOTO main[/code]
I have an output on my Parallax USB Oscilloscope, I put a high and a low on a different pin so I could frame in where the signal is. I would post a picture but I don’t feel like finding a place to post it. My first question is are you really wanting to send two bytes here for the beep?
The [262] is actually two bytes. In hex: 01, 06
Let me know if that is correct before I try doing the same on BAP.
Kurt
It looks good but I dont think you need the LOW 0 command. I have not used it and it works well with the stamp.
The [262] is correct, it works with the stamp.
Hi Mike,
The Low and the high commands are not needed for the serout, but I used them as another pin to show on the oscilloscope. The red trace shows this on the bitmaps while the blue trace shows the output of the serout command. I sent email to you and Nathan. Notice the differences in the traces and timing between the BAP and BS2…
Kurt
Thanks Kurt for the time and effort. The two images look close, could this time difference be enough to cause this problem?
You are welcome. I just sent you and Nathan an image that used photoshop to overlay the i9600 wave of the BAP with the output of $54 on the BS2. The waves look identical.
So if the sending on the 262 does not work the same on the BAP as the BS2 when you use i9600(BAP) or $54(BS2) then I am not sure what is happening.
Have you tried using the seperate power supply you mentioned earlier?
Kurt
Yes, the seperate power supply did not work. After the results you posted, I am thinking the BAP is possibly dammaged.
There was a time when the BAP worked well with the SJ board but this was before flow control was fixed in the latest IDE release. I must have dammaged the BAP somewhere before the last two IDE releases. The next option is to try another BAP to rule out a faulty BAP.
Perhaps I can send it to you to ckeck it out?
Hi Mike,
The next thing I would do is to re-install the 8.0.1.0 release and see if by chance you can get it to work. Nathan saw something in my traces I sent to both of you that he wants me to check out. My scope set up is rather limited as the trace buffer is so small. But it has helped me to localize and issolate a few issues.
We will see if it makes sense for you to ship it out to me or not. Hopefully we can find out the problem before it comes to that.
Good Luck.
**Edit -**Looking over your previous posts I see you got it to work earlier with N9600. So if I get time later today or tomorrow, I will try to see the differences (if any) between the output of the one character on the current beta 8.0.1.3 and the earlier version…
What I saw in the trace(and confirmed by a second trace) was that the non-inverted serial mode is not outpuing ANY pulses. It remains high the whole time. I’m going to fix it this weekend.
fantastic, I look forward to the fix.
Here is my test code:
main
serout p0,i9600,[0xa5]
serout p1,n9600,[0xa5]
pause 10
goto main
I checked this on a scope. The n9600 was an exact mirror of the i9600 signal. Kurt I think there may be a problem with your osilloscope. Maybe it’s not triggering correctly on the non-inverted data. Can you try the above test code and get back to me?
