Hi I am trying to use CC5x due to BoostC not supporting baseline micros. Unfortunately, CC5x is not altogether clear on how to define some of the #pragma settings. Its help refers you to the respective chip header file, but with the desired chip there is little you can see below I have tried various combos of config, and all of them error out. There seems to be no clock_freq pragma. Any pointers appreciated. Thanks, Alistair.

#pragma config _WDTE_OFF,_MCLRE_OFF
^------
Error C:\Projects\PIC\cc5x\mytest.C 3: Preprocessor error
(The source line starting with '#' contains invalid syntax or context
dependent syntax)


//#pragma config WDTE=off, PWRTE=off, MCLRE=off,CP=off
//#pragma config _PWRTE_OFF & _WDT_OFF //& _MCLRE_OFF _CP_OFF &
//#pragma config CP=OFF PWRTE=OFF,WDT=OFF,INTOSCIO
#pragma chip=PIC10f206
#pragma CLOCK_FREQ 125000 //Set known clock frequency to prescaler


// HEADER FILE
#pragma chip PIC10F206, core 12, code 511, ram 8 : 0x1F
// NOTE: last code location is omitted ^--

#pragma resetVector 0

#pragma config_def 0x0010
 

Actually I can now see where its going wrong. It does not seem to conform to Microchip specs in options available for chip.Compared to BoostC CC5x (for me anyway) is a horror to configure. EG there is no WDTEN bit as per app specs eg the following is illegal: #define wdt CONFIG.WDTE //Watchdog control bit

How to get access to the CONFIG register is obscure.
Thanks,
Al.
 

Hi it was a wee bit tricky but the key information is available here it is:
EXAMPLE ON HOW TO USE THE STANDARD MPASM CONFIGURATION IDENTIFIERS

1. First copy the identifiers from the right .INC file
(P10F206.INC) in the MPASM Suite directory into an
#asm .. #endasm region in a header/source file.

2. Then use the EQU identifiers together with the '&' operator

EG in my CC5x PIC10F206.H file in the CC5x directory I modified it with the MPASM data thusly:
Code: 
#asm
_MCLRE_ON                    EQU     H'0FFF'
_MCLRE_OFF                   EQU     H'0FEF'
_CP_ON                       EQU     H'0FF7'
_CP_OFF                      EQU     H'0FFF'
_WDT_ON                      EQU     H'0FFF'
_WDT_OFF                     EQU     H'0FFB'
_IntRC_OSC                   EQU     H'0FFF';IntRC_OSC is the only option.
                                            ;It is here for backwards compatibility
                                            ;only.
#endasm

Then within the C code you can define these (missing) Options thusly:
#pragma config = _WDT_OFF & _MCLRE_OFF & _CP_OFF

Hope this helps someone!

Al.
