Yes I was thinking about that but that is the most painful solution because
my application is already huge (about 48kbytes! in 18F2620). Unfortunately
this solution I think will be the only one......

I don't understand how you can write cyrillic with ascii characters?

Hello everyone!
Is it possible to find somewhere character LCD display (2*16) with cyrillic
alphabet?I need to realize russian language menu system! Or maybe LCD display with more than just 8...

That helps Bruce!
By careful comparision of every fuse programmed with and without bootloader I noticed some XINST=Extended Instruction Set Enable Bit which was dissabled in working version and...

Sory guys,
my mistake due to hurry, I use WinPic programmer and yes, I checked all fuses that I programmed. The LED blinking program works very well so I think
that the programmer is doing his job...

I'm very disappointed because I have a huge application which controls
solar machine and it works great and my customer is very satisfied.
Because of new features planing to add I have to migrate...

Sorry, I forgot to paste that part of code:


@ __CONFIG _CONFIG1L, _PLLDIV_5_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_1_1L
@ __CONFIG _CONFIG1H, _FOSC_HS_1H
@ __CONFIG _CONFIG2L,...

Dear friends, please help or I'll go crazy. This seek simple code doesn't work
on 18F2550. Of course, it works on good old '876.


@ __CONFIG _CONFIG1L, _PLLDIV_5_1L & _CPUDIV_OSC1_PLL2_1L &...

Have you tried put the line
ADCON0=0

I installed MPLAB 7.50 and it works now, but I have to rename file mpasmwin.exe to mpasm.exe because MCS obviously searches file
mpasm.exe not mpasmwin.exe. Is this usual method? I use PBP pro...

Yes! I'll try with different MPASM version, no other ideas.

Hello everyone!
My program is about 8000 14-bit words when compiled for 16F876.When I transfer the design to 18F2550 and compile it inside MPLAB IDE I can see in lst file that my program is about...

Thank you very mach Mister E!
It works now! i was in a hurry and didn't look at datasheet with enough
attention.
Thanks again.

Why then this piece of code doesn't work on Atmel 24C256 and works with
24LC32A from Microchip? I get five times 04 on LCD in case of Atmel chip.
The hardware configuration is the same: pin1,2,3,8...

Hello pic friends!
One simple question. Is it possible somehow to read and write
24C256 eeprom from Atmel with i2cread and i2cwrite commands?
the protocol is 2 wire, not i2C but it looks similar?

It works!
My boot sector starts at LBA=32 because my card has 32 hidden sectors!
Well, I have first step on thousand miles trip!
Ruben, Thanks again for help!

Thanks for reply Ruben
but I still don't understand something.
you are talking about partition table which starts at 446. On offset 8 from 446 which is
$01C6 that you mentioned it should be value...

Hello PIC friends!
I have Compact Flash modul from Mikroelektronika connected to PIC 16F877 with 20MHz xtal.
I use 64 Mb Lexar's CF card. I want to read four bytes from the begining of boot sector...

I also prefer books and have both Predko's book
and Pic in practice by David Smith.
Myke Predko is huge book more for people whose
all life is in somehow related to PIC :-)
You will find...

J Brittian:
Nice clean and seven times faster, but it doesn't matter.
We ddiscussed it already.

kamikaze 47:
well, of course it's better to use asm in my opinion
but this also work. I try it.

You always have to clear interrupt flag in software
before retfie instruction. If you don't clear the flag,
instruction retfie will set GIE bit and PIC will be
interrupted again. Logical AND...

first off all you forgot to clear int flag
in your int handler so your PIC will always
be in interrupt routine. you have to put line


bcf INTCON,1

before retfie instruction.
also I suggest...

I comment out this part of code but still have the same situation...

Hello dear pic friends and sorry for bad english!
Yesterday in my lab I have some strange int behaviour
So, when I wrote simple task like this:

define LOADER_USED 1
define OSC 16
TRISC.3=0...
