Trouble Configuring Fuses for PIC18F4525 in Proton

[laserline]

Hello everyone,

I've been trying to use the PIC18F4525 in my project but I'm facing difficulties with correctly setting up its configuration bits. I've attempted the following approaches among other variations, but none seem to work:

Config1H  OSC_INTIO67_1, FCMEN_OFF_1, IESO_OFF_1
Config2L  PWRT_OFF_2, BOREN_OFF_2, BORV_2_2
Config2H  WDT_OFF_2, WDTPS_256_2
... through to the end.


Config1H = OSC_INTIO67_1, FCMEN_OFF_1, IESO_OFF_1
Config2L = PWRT_OFF_2, BOREN_OFF_2, BORV_2_2
Config2H = WDT_OFF_2, WDTPS_256_2
... and the rest down the line.


Config_Start
    Config1H = OSC_INTIO67_1, FCMEN_OFF_1, IESO_OFF_1
    Config2L = PWRT_OFF_2, BOREN_OFF_2, BORV_2_2
    Config2H = WDT_OFF_2, WDTPS_256_2
... through to the end.
Config_End


I'm at a loss for what to try next. Does anyone have any tips or suggestions on how to properly set the fuses for this microcontroller using Proton? Any help would be greatly appreciated.

Thank you in advance!

Hi,
Have you tried the really good Fuse configurator, it is built in to Positron studio or should be available as a stand alone for the existing IDE.

Not really, but it's good advice.

Yes... Pepe's suggestion solved my problem!

Thanks a lot!!

Pepe's suggestion is using the Fuse Configurator!
