just got my board, not working right

Archiver

My BS2p40 Professional Starter kit just arrived. I also purchased
the Audio Amplifier Appmod kit for it.

After trying the "hello world" program listed in the manual, and then
a couple other simple programs, I plugged in the Audio Amp board and
loaded the StampSounds.bsp program.

It runs, but it doesn't sound right at all; I only hear a bunch of
clicking. The DTMF sounds, the phone ringing and busy sounds, the
astro droid: all of them are just clicking noises. The roulette
wheel sounds right, because I guess it's just supposed to be clicking
anyway. The Howler and Space Transporter actually make a slight
squealing sound, but they still don't sound like they should.

Is there some trick to getting this thing to work right? I also
connected a separate audio amp/speaker to the external speaker jack
on the audio board and I get the same results.

Hi Andy,

The BS2P operates at a different frequency than the BS2 so the DTMF
and FREQOUT commands require different values.

Add this to the top of your program (below the stamp identifier):

{$PBASIC 2.5}

#SELECT $STAMP
#CASE BS2, BS2E
PER CON $0100
FREQ CON $0100
#CASE BS2SX
PER CON $0266
FREQ CON $0066
#CASE BS2P
PER CON $0343
FREQ CON $0043
#ENDSELECT

and then change every FREQOUT command so that they use the following
syntax:

FREQOUT Pin, Duration */ PER, Freq1 */ FREQ {, Freq2 */ FREQ}

Example:

From:

Dial_Tone:
DEBUG "Dial tone", CR
FREQOUT Speaker, 35, 35
PAUSE 100
FREQOUT Speaker, 2000, 350, 440

To:

Dial_Tone:
DEBUG "Dial tone", CR
FREQOUT Speaker, 35 */ PER, 35 */ FREQ
PAUSE 100
FREQOUT Speaker, 2000 */ PER, 350 */ FREQ, 440 */ FREQ

Just go through the code and add the "*/ PER" and "*/ FREQ" to the
Duration and Frequency parameters of each of the FREQOUT commands.

The DTMF commands also need to be changed, but I don't have the
modifiers handy at the moment.

HTH,

Kenny
