PIC 16LF722 + PIC KIT 2 //configuration problem

[pomerol]

I need some help!
I'm not able to do a simpe led blinking with this new microprocessor.

I'd like to use the internal 16Mhz clock

Thanks

I may be wrong...but I do not think Pic Basic supports that chip?

Latest Release: 2.50
DOWNLOAD PATCH to 2.50b:
Adds support for PIC16F722, 723, 724, 726, 727, PIC16LF722, 723, 724, 726, 727, PIC18F6393, 6493, 6628, 66J11, 66J16, 6723, 67J11, 8393, 8493, 8628, 86J11, 86J16, 8723 and 87J11.

F, LF, it's all the same but different.

Guess I need a patch :o

This is what you need in the config line then


_INTRC_OSC_NOCLKOUT

Then look in the data sheet under the OSC section at the OSCON register.

Yes, LF is different from F and I'm using a different programmer (pickit2) running at 3.3 volts.

Using AN589 and ICprog I made a lot of project in the last 3 years.

I'm using the 2.50 version and I can see the PIC in the processo list.

My question is regardin the configuration bits, using PICKIT 2.

How I can select any bits of configuration word 1 (CONFIG1) using PBP 2.50, like @CONFIG or OSCCON %01001110 or __CONF or ... like described on pade 89 of PICF72X/PIC16LF72X manuals.

I want, for the moment, to see just a led blinking.

Thanks

I'm using:
- Melabs default (PM) assembler.
- PBP 2.50b
- PICKIT 2
- PIC 16LF722
- one led connected to portb.0

How I can set the micro for the internal 16Mhz oscillator?
How can I select the single parameters in the configuration word 1 (CONFIG1) like described on page 89 of PICF72X/PIC16LF72X manuals?
How can I write the PBP commends?

Thanks
Bye

I got patched up :)
This is a cool chip, I need to get some.
The code below should blink an LED, on for 1/2 second and off for 1/2 second.

I do not use PM, so the config line for PM may not be correct.
The code as is works with MPASM. I will suggest you start using MPASM as you will need it for other chips and/or projects.

Also, if you are new to all of this a different chip might be better to learn on. 16F676,16F88 ??

Hope this works for you.


'16F722
'SETS UP THE INTERNAL OSC FOR 16 MHZ

I usually modify the PIC16FXXX.INC file, the one that PBP includes (I program with MPLAB), did not know it can be done like that :eek:.


I saw this chip too and, like you, need to get some, and if you're stunned, look at this:
