darn ok cool thanks!

I guess eeprom or editing the linker is the only way to gain ram(SPACE)

AtomSoft · 5th July 2009, 11:04 PM

Can someone help me create a 800 byte buffer lol its for a 18F2525

This is my usage so far:

DirtyLude · 5th July 2009, 11:07 PM

You can reflash pages within your program, same way you do with a boot loader or serial programmer, but that's really meant for permanent storing variables that you don't want lost in a power down.

If you want RAM, you can use SRAM rather than EEPROM, which is faster, but obviously you lose everything on power down.

DirtyLude · 5th July 2009, 11:09 PM

You just want a FIFO buffer? If you search 'ring buffer' and 'C library' and combinations, there's lots of example code for it out there.

AtomSoft · 5th July 2009, 11:10 PM

oh man i even forgot about the option for external ram lol thanks!

Any thoughts of internal (software) type fixes for now?

AtomSoft · 5th July 2009, 11:11 PM

I need it to store the entire screen. Like this dude did but on a ARM7. Its a pain in the butt for C18

3v0 · 5th July 2009, 11:22 PM

If you are getting the error
Error [1300] stack frame too large

A simple way to fix it is to make the variable global.
If you put it inside main or any other function it will allocate memory from the stack. If you make it global it does not.

Give it a try.

im getting this:

Code:

MPLINK 4.31, Linker
Copyright (c) 2009 Microchip Technology Inc.
Error - section '.udata_nokia7110.o' can not fit the section. Section '.udata_nokia7110.o' length=0x00000304
Errors    : 1

Im trying to create:

Code:

unsigned char ScreenBuff[770];

DirtyLude · 5th July 2009, 11:37 PM

You could make up a scheme to code everything. It's complex, but since there's mostly blank columns your buffer could be encoded sort of like RLE (run length encoding), but modified. I can envision what it would take, but it would be complicated to maintain. Your buffer would be dynamic and data would need to be moved around a lot. It would also mean that you couldn't have too much data on the screen or your buffer would have the potential to grow larger than a straight dedicated buffer.

AtomSoft · 5th July 2009, 11:40 PM

The only fix i know of is :

Code:

#pragma idata bigdata
    unsigned char ScreenBuff[770];
#pragma idata

Linker Modification :

Code:

DATABANK   NAME=gpr10      START=0xA00          END=0xDFF	//END=0xAFF
//DATABANK   NAME=gpr11      START=0xB00          END=0xBFF
//DATABANK   NAME=gpr12      START=0xC00          END=0xCFF
//DATABANK   NAME=gpr13      START=0xD00          END=0xDFF
....
.....

SECTION    NAME=bigdata    RAM=gpr10

Thanks guys here are some of the functions i have working.

Code:

void LCDCircle(char top, char left, char radius);
void SetPixel(unsigned char top, unsigned char left);
void LCDRect(char x0, char y0, char width, char height);
void LCDImage(rom unsigned char *image,char left, char top);
void LCDLine(char top0, char left0, char top1, char left1);
void LCDChar(unsigned char letter,unsigned char font,unsigned char style,unsigned char top, unsigned char left);
void LCDString(rom unsigned char *str,unsigned char font,unsigned char style,unsigned char top, unsigned char left);

All working 100% so far. Will release in a week or so
