Hi,
Below is a sample code that's supposed to flash 8 LEDs on port b at 5 Hz. I
have modified the .h file to correspond to the one included in the latest
SDCC snapshot. However, I'm not sure how to change the "#pragma config..."
line to correspond to the same command in SDCC. That particular line
or 2: Initializer element is not constant

Hi Raphael,
PIC18fregs.h is indeed in /usr/share/sdcc/include/pic16. I think the problem
is that SDCC does not look into pic16 directory on its own. Only my source
files are in folders with names that have white space. I did indeed install
SDCC into a blank-free path, which is in /usr/share/sdcc/.
.c:4: Initializer element is not constant
main.c:5: Undefined identifier '_BODEN_OFF_2L'
main.c:5: Initializer element is not constant
main.c:7: Undefined identifier '_MCLRE_MCLR_disabled_RA5_input_en_3H'
main.c:7: Initializer element is not constant
Thanks,

Once again, thanks to Jan and Raphael for their help for getting me started
with a template for the C codes on SDCC fusebit syntax. My newest version of
the LED blinking code is posted on
http://www.dutchforce.com/~eforum/index.php?showtopic=14788.
However, I am having a problem of my PIC18F2620 n
When I checked with the oscilloscope on the power supply regarding its
stability, the supply voltage is very consistently regulated at 5V and the
raw power supply voltage consistently at ~15V.
Jan, I'm currently building the project using Piklab after I have the newest
version successfully install
dc source at the same time,

clean:
rm -f *.o *.rel *.lst *.cod *.hex *.map *.asm# change this to your

Does anyone have any idea on how to get around that? I have a feeling that
it has something to do with 18f2620.lkr file.
Thanks,

wrong with the linker options, however I have trouble deducing from the
Makefile what's wrong with the options.

Really sorry for the spam. Hopefully I can get into a situation to reduce
the amount of help emails needed.
Thanks for the help,

I'm not sure if my last message went through b/c of the file limits, so I
guess I'll repeat the message except link the files to a file hosting site.
I'll start with replying to soliton's questions first. Here are the
printouts for where sdcc, gpasm and gplink are installed.

external power is applied. I'm thinking of trying the same code (except for
some fusebits/hardware tweaks on a PIC16F877A, PIC16F688, PIC16F690, or
PIC16F628. Any suggestions if this thought is a feasible alternative to
sideline the development?

Hi Jan,
I'm using a PICKIT 2 from Microchip. Using Jeff's pk2 command line program
to flash my code into the program memory. Already contacted pickit-pro
development mailing list and himself.

Sorry for the late reply. Haven't been working on it lately since I have had
trouble installing the latest edition of ubuntu on my computer that had me
having to reinstall all the necessary packages. I tried to verify the config
files between the mcu and the pk2.cfg. I'm getting the following:

Looks like Jan is right after I took his suggestion to increase the delay
rate. The LED blinking program is working now. Finally thanks for all your
help.

modified correctly. How would I disable adc_int in adcval function? Do I
turn off all the ADIE bit when I read the a/d conversion value, and then
turn it back on?

Any insights? Are there still holes with the adc patches?
