Serout/serout2

[mister_e]

As far as i'm aware of, Stamp and PBP is not as this different... can you post the Stamp code?

Mr. E, I feel like the guy at the piano. Here's the BS2 code
FM CON 14
HIGH FM
Start_Up:
SEROUT FM,396,[$55,$00] '00 is the stop command
PAUSE 5000
SEROUT FM,396,[$55,$03,$40] 'first speed command
PAUSE 5000
SEROUT FM,396,[$55,$03,$80] 'second speed command

This repeats through several speed steps and loops back with GOTO Start_Up: The $55 is the sync, $03 is the set DC speed and the last part of the string is the 00 to FF speed levels. Details of this are from the Solutions Cubed group.
I tried using SEROUT and SEROUT2 with different mode numbers, string precedes, INCLUDES, DEFINES. Since the pinouts are different between the BS2 and 16F628 I could have had the pin path wrong. I tried to work this out with no change. Thanks for any help with this. JS

mm are you saying that even if you change our code to...

FM VAR PORTB.4
HIGH FM
Start_Up:
    SEROUT2 FM,396,[$55,$00] '00 is the stop command
    PAUSE 5000
    SEROUT2 FM,396,[$55,$03,$40] 'first speed command
    PAUSE 5000
    SEROUT2 FM,396,[$55,$03,$80] 'second speed command

It doesn't work???

you must use SEROUT2 to be BS2 compatible with the baudrate definition. 396 should be 2400,8,N,1. If you want to use SEROUT you'll write it like..

FM VAR PORTB.4
HIGH FM
Start_Up:
    SEROUT FM,0,[$55,$00] '00 is the stop command
    PAUSE 5000
    SEROUT FM,0,[$55,$03,$40] 'first speed command
    PAUSE 5000
    SEROUT FM,0,[$55,$03,$80] 'second speed command

I tried both versions with the same result. I added DEFINE CHAR_PACING with different values, no go. I wrote a blink routine for PORTB outputs and they all checked good. The MCS is a little tricky to work with so I have been double checking the parameters before programming. I am using the internal osc. and have DEFINED it so in some programs, again no change. My scope is down with a bad cap and the part won't be in for awhile so there isn't a good way to look at the output. Digital voltmeter and connection checks show nothing unusual. Not a very good day at the keyboard. I seem to have hit the brick wall. Later JS

If you use MPASM as assembler try...

    @ __CONFIG _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_ON & _MCLRE_OFF & _LVP_OFF & _BODEN_ON 
         ' Internal Oscillator
         ' Enable watch dog timer
         ' Enable power up timer
         ' Disable MCLR pin
         ' Disable low voltage programming
         ' Enable brown out detect

if you use PM as assembler, look and try all the suggestion in the FAQ section. There's a full thread wich discuss of HOW TO.

here it is => http://www.picbasic.co.uk/forum/showthread.php?t=543

If the MCS config. options list is correct regarding the device setup, why should it be necessary to add the redundant assembly code? Which has last say, the actual program code or the IDE controlling the up load. Never the less when I try adding the device config lines as they are presented from the site all I get is:
ERROR 16F628~5 ASM 45:[235] opcode expected instead of 'PIC16f628'

If I take the 16f628 out of the line, the error code changes to:
ERROR 16F628~ 5 ASM 45: [235] opcode expected instead of intc_osc_noclkout

The basic questions are:
What am I doing wrong regarding the code? If the program is OK,
Is it a hardware or sofware problem? Other options woulld be to: try another chip or install PBP into the MPLAB. I'm not ready for the latter. I guess my frustration is showing. JS

O.K. Let's try something first. A very simple test program test to send a text string to your PC via COM port. You'll use the MCS serial communicator (F4 then F9 to connect to the PORT)

if you use PM as assembler, use the following config fuses OR set them manually.

    '
    '    Hardware configuration
    '    ======================
    asm     
        DEVICE PIC16F628, INTRC_OSC_NOCLKOUT ; Internal Oscillator
        DEVICE PIC16F628, WDT_OFF            ; Disable watch dog timer
        DEVICE PIC16F628, PWRT_ON            ; Enable power up timer
        DEVICE PIC16F628, MCLR_OFF           ; Disable MCLR pin
        DEVICE PIC16F628, BOD_ON             ; Enable brown out detect    
        DEVICE PIC16F628, LVP_OFF            ; Disable low voltage programming
        ENDASM

is the above work?
