Post by thread:[PIC]:MPLAB 18F452 config bits syntax

I'm looking for some guidance on the proper syntax for setting 18F config bits in MPLAB. What I've done _looks_ like the examples I've found, but clearly I'm missing something. What I've tried: include "P18F452.INC" __config _config1H, _HS_OSC_1H __config _config2H, _WDTPS_128_2H & _WDT_OFF_2H __config _config2L, _BOR_OFF_2L & _PWRT_OFF_2L __config _config3H, _CCP2MX_OFF_3H __config _config4L, _STVR_ON_4L & _LVP_OFF_4L & _DEBUG_OFF_4L What I get: Error[113] C:\PROGRA~1\MPLAB57\PBCAV101.ASM 38 : Symbol not previously defined (_config1H) Error[126] C:\PROGRA~1\MPLAB57\PBCAV101.ASM 38 : Argument out of range (not a valid config register address) Error[113] C:\PROGRA~1\MPLAB57\PBCAV101.ASM 39 : Symbol not previously defined (_config2H) Error[126] C:\PROGRA~1\MPLAB57\PBCAV101.ASM 39 : Argument out of range (not a valid config register address) Error[113] C:\PROGRA~1\MPLAB57\PBCAV101.ASM 40 : Symbol not previously defined (_config2L) Error[126] C:\PROGRA~1\MPLAB57\PBCAV101.ASM 40 : Argument out of range (not a valid config register address) Error[113] C:\PROGRA~1\MPLAB57\PBCAV101.ASM 41 : Symbol not previously defined (_config3H) Error[126] C:\PROGRA~1\MPLAB57\PBCAV101.ASM 41 : Argument out of range (not a valid config register address) Error[113] C:\PROGRA~1\MPLAB57\PBCAV101.ASM 42 : Symbol not previously defined (_config4L) Error[126] C:\PROGRA~1\MPLAB57\PBCAV101.ASM 42 : Argument out of range (not a valid config register address) Any and all guidance would be appreciated, even if it's sprinkled with admonishments for things I've been able to unearth from the manual or by googling.

The current MPLAB does NOT support the old syntax of __CONFIG Look back a few weeks ago, this is well discussed and I included a working example. Or you could READ the P18F452.INC file to see for your self. Rob Robson wrote: {Quote hidden}>I'm looking for some guidance on the proper syntax for setting 18F config >bits in MPLAB.

Have you tried all caps? Like so: __CONFIG _CONFIG1H, _HS_OSC_1H That's the only difference I can see, but if you have case sensitivity on, it might make a difference. I do know that the __CONFIG directive has been "deprecated", in favor of a newer format, but aside from a little grumbling, MPASM still accepts it. Which is good, because it seems changing to the newer format breaks something in PICBASIC. Mike H. PS- If anyone can tell me how to exclude a certain warning level from showing up in the output window, I'm all ears!

It now uses CONFIG for 18C/18F PICs. __CONFIG is still supported for many PIC18C/18F PICs but the use of __CONFIG is deprecated. In fact, MPLAB does not support __CONFIG for some new PIC18J chips. Take note that gpasm does not support CONFIG yet. Regards, Xiaofan

I just installed 7.22 freshly downloaded about five days ago, and it assembles my "__CONFIG" with only minimal grumbling (warning 230)... > The "current MPLAB" *I* am using does... > > I *think* __CONFIG is unsupported for the 16-biters, thought... ...and I'm using that on a 16-bit 18F2320. The 230 warning DOES specifically state that __CONFIG has been deprecated for PIC18 devices, but it still works just the same- changing a setting in the __CONFIG directives causes it to change in the dialog box for the project.
