Since this forum is for PicBasic, here's a simple test routine to check out the EMIC module.

DEFINE OSC 20

' -----[ I/O Definitions ]---------------------------

Tx    VAR PORTC.0   ' wire to EMIC sin pin
Busy  VAR PORTC.2   ' wire to EMIC busy pin
Rst   VAR PORTC.1   ' wire to EMIC reset pin

' -----[ Constants ]---------------------------------

BAUD            CON     0  ' T2400
Yes             CON     1

' -----[ Initialization ]----------------------------
  TRISC = %000010100
  
Setup:
  GOSUB Hard_Reset                 ' restore defaults
  PAUSE 1000
  SEROUT TX, Baud, ["volume=7;"]   ' max volume
  GOSUB Check_Busy
  SEROUT TX, Baud, ["pitch=1;"]    ' adjust voice pitch
  GOSUB Check_Busy
  SEROUT TX, Baud, ["speed=1;"]    ' set speech speed
  GOSUB Check_Busy
  
Talk:
  SEROUT TX,Baud,["say= I should be using pick basic pro;"] 
  GOSUB Check_Busy    ' wait for busy to release
  PAUSE 10000         ' long pause between message
  GOTO Talk

' -----[ Subroutines ]---------------------------------
' -- wait until Busy line released by Emic

Check_Busy:
  PAUSE 5                      ' allow busy time to activate
  WHILE Busy = Yes : WEND      ' wait until not busy
  RETURN
    
' Hard reset
' -- good when comm link is lost

Hard_Reset:                      ' reset to default values
  LOW Rst                        ' pull reset line low
  PAUSEUS 200                    ' 200uS pause
  INPUT Rst                      ' let reset float

  RETURN

I've included the .hex file here for you. Wire your 16F876A to the EMIC as shown in the I/O
Definitions section, and program it with the .hex file attached.

If it doesn't work, then you may have a damaged EMIC module, bad speaker, or something
isn't wired properly. If it does work, let me know.
