i want to interface PIC 16F877 with PWM coprocessor PAK-5. can i directly connect the USARt tx pin of pic with Rx pin of pwm cop?" |Delete 'P-' before: '' but after: 'mgore@cv.cl shares this code:
HI

I used the hardware configuration shown in
http://www.parallax.com/dl/docs/cols/nv/vol1/col/7.pdf
connected to a PIC16F877A,but  had problems of instability.    
I configure bad the CM8880PI?

The source code here:

#DEFINE        RW              PORTE,0         ; RE0 Read/Write
#DEFINE        RS              PORTE,1         ; RE1 Register Select
#DEFINE        CS              PORTE,2         ; RE2 Chip Select


       movlw  b'00000111'
       movwf   PORTE                   ; RW,RS,CS = 1
       
       call    DELAY250                ; 250 mS Delay

       bcf     CS                      ; CS = 0               

       movlw   b'00001001'             ; to A register 
       movwf   PORTD           

       
       movlw   b'00000000'             ; to B register
       movwf   PORTD
      
       bsf     CS                      ; CS = 1

       bcf     RW                      ; Write mode
       bcf     RS                      ; Output register 

       movlw   (The code to send)
       movwf   PORTD
       bcf     CS
       nop
       bsf     CS

                
Note: 
The PORTD is used to data bus from CM8880.
The phi2 input is connected to Vcc by 3.3Kohm resistor.
 

Somebody knows the correct form of configuring and operate the CM8880?


Thank you in advance
