Voice Playback CHIP SD20

[robert.quaas]

Recently purchased a voice chip called SD20; Here is my code for PIC16F88, can not seem to get it to work.

If you look at page 12,13; and page 20 for info.

Attached is part of the datasheet document pages 1-13, I will post others up due to size limits.

appreciate some help on this ......


@ DEVICE XT_OSC,MCLR_OFF,LVP_OFF,WDT_OFF,PROTECT_OFF

DEFINE LOADER_USED 1

Include "Modedefs.Bas"

' ** Setup the Resonator Frequency, in Mhz **
Define OSC 4

' DEFINE SHIFT_PAUSEUS 100

ANSEL = 0 'Configure all pins to digital operation since not using ADC
'(Analog to Digital Converter)


Baud con 84 ' 9600 baud rate

' ** Port configurations **

TX VAR PORTB.5
RX VAR PORTB.2

CLK VAR PORTA.4
DI Var PORTA.0

PIEZO VAR PORTB.7

DAT VAR word


Init:

TRISA=%11111111 ' Set PortA TRIS register
TRISB=%00000000 ' Set PortB TRIS register

begin:

low piezo
high CLK
high DI

dat = $FFF7
serout2 tx,baud,["1st Data = ",bin16 dat,13,10]
Shiftout DI, CLK, 1,[dat/16]

dat = $3
serout2 tx,baud,["2nd Data = ",bin16 dat,13,10]
Shiftout DI, CLK, 1,[dat/16]

dat = $fffe
serout2 tx,baud,["3rd Data = ",bin16 dat,13,10]
Shiftout DI, CLK, 1,[dat/16]
