16f883

Hi folks,

I got a bunch of 16f883 chips last week, and am having some ah, issue, with the clock progrmamming in PBPro.
Using the string:
'INITIALIZE
@ DEVICE INTRC_OSC_NOCLKOUT, MCLR_OFF, WDT_OFF, BOD_OFF, PWRT_ON

I get an illegal operation warning when it compiles. It's complaining about the clock statement. Ok, so continuing blindly along, I set the Oscillator to either INTOSC IO or INTOSC Clockout in the Config window, and press Program, returns an error and a whole bunch of mismatch in the compare. The Config dropdown reverts to XT for the clock and all is not overly happy.
What the heck.
I've changed the INTRC to every flavour that I can find in the datasheet and it's simply does not want to go.

Anybody have any insight?

Cheers
Gary

Gary, I was just reading "THE FUSES SETTING SAGA" few days ago, I think you should read it to have the insight you are searching.

Thanks Al,

Having just read enough of that nonesense to really give me a headache, I'll just go back to using the trusty 12f675 chips. This stuff clearly does not need to be this complicated, with soooooo many niggly differences based on what Microchip was thinking on that particular day. For some of us (me particularly) I have 4 different telephony manufacturers worth of niggly data plugging my cells, and can't rmember 1/2 of that stuff I -need- every day!

Pics should be fun, not another reason to spend hours digging through freakin datasheets for that one bit of data that puts you back on track, or necessitating reams of posts to get supposedly "simple" stuff working.....

(Maybe it's time for a holiday)

What version of PBP are you using?

[Meriachee]

Dave,

PBP 250c
Microcode Studio 3.0.0.5
MPASM/MPLAB/win 8.36
Using the MELabs U2 programmer with MEup46 Firmware.

The funnny thing is, I've never been able to get the "@ device, blah blah" stings to work, and I've been through almost all the possible iterations every time I try, even cutting and pasting directly from posts, from people who seem to know what they are talking about...... I'm sure that it's some stupid user thing, but eventually something should work.........

All I want to do is use the 16F833 with the internal oscillator. Can't be that difficult. (My code, however.. heh..heh..)

Hi Gary,
You need to open the 16F833.inc file located in the PBP Root directory and add a semicolon ahead of the default configs. Then the @ DEVICE . . . will work without the error message. There are configs for both PM and MPASM assemblers there. You will have to redo this when you "UPGRADE" PBP to a newer version as the upgrades overwrite those files. You must do this for each part number PIC you are using to use anything other than the default config, or modify the default config to your particular liking.
