unable to set config bits

[JFinlayson]

Hi I have write config on download flag set in Project options dialog, configure. But unable to change internal oscillator speed or no matter what oscillator I set pic 8 keeps running at 1Mhz. So looks like I am unable to set configuration bits.
I am using latest version of Flowcode 7 and latest version of Microchip XC8 V1.4 compiler. Is there any other way to send configuration to chip?

Hi
Are you setting the OSCON Register with the flowcode Oscillator Helper or you have to do it with a C code component
if you can post a minimum project then we could help you

I set the oscillator speed in project options, general options as in program attached

The setting in project options just tells Flowcode what speed the oscillator is set to. It does not set the value on chip. To actually configure the oscillator on the chip you need to use a C code icon and set the PIC registers to the correct values.

The code to use the internal oscillator at 8 MHz for your device should be:

Code: Select all

OSCCON = 0b01110011;

Ok Thanks is it just the oscillator speed setting that is not sent?
I presume the other config bits are programmed?

Oscillator speed is not part of the configuration bits, it is a separate register. The configuration bits are programmed.
