Hi All,
I put myself down as a newbie even though I played with Pic's over a year ago.
The problem I have stems from I had a severe brain injury and had to undergo surgery, and since then I have had problems remembering things.
I've had to start leaning about Pic's and PBP from scratch really.
To help myself I bought an easypic 6 but decided to stick with PBP instead of Mikrobasic (had a quick look and it seemed really hard compared to PBP)
I cant figure out what I'm doing wrong,
I'm trying to get the simle "hello world" lcd test working but it just wont
My code is as follows
I set it like that after studying the easypic manual and lcd that came with itCode:'**************************************************************** '* Name : Test.BAS * '* Author : Lewis * '* Notice : * '* : All Rights Reserved * '* Date : 07/12/2009 * '* Version : 1.0 * '* Notes : * '* : * '**************************************************************** @ DEVICE pic16F887,HS_OSC 'LCD DEFINATION DEFINE OSC 8 DEFINE LCD_DREG PORTB ' Set LCD Data port DEFINE LCD_DBIT 0 ' Set starting Data bit (0) DEFINE LCD_RSREG PORTB ' Set LCD Register Select port DEFINE LCD_RSBIT 4 ' Set LCD Register Select bit, Port B.4 DEFINE LCD_EREG PORTB ' Set LCD Enable port DEFINE LCD_EBIT 5 ' Set LCD Enable bit, PORTB.5 DEFINE LCD_BITS 4 ' Set LCD bus size 4 bits DEFINE LCD_LINES 2 ' Set number of lines on LCD to 4 Lines DEFINE LCD_COMMANDUS 2000 ' Set command delay time in us DEFINE LCD_DATAUS 50 ' Set data delay time in us '******************************************************************************* pause 500 ' Wait for LCD to startup loop: Lcdout $fe, 1 ' Clear LCD screen Lcdout "Hello" ' Display Hello Pause 500 ' Wait .5 second Lcdout $fe, 1 ' Clear LCD screen Lcdout "World" Pause 500 ' Wait .5 second Goto loop ' Do it forever
I use MicroCode Studio
The programmer is the picflash program that came with the easypic board, the xtal is 8Mhz
When I write the program in Microcode Studio I get a wierd effect when choosing a 16F887 PIC
the ICD Compile row of buttons goes greyed out, yet they dont when choosing a 16F877
Does this matter?
I get the following error when I compile I have no idea what it is.
Warning [207]C:P\pbp\tests\lcdtes~1.asm 108 : found label after colum 1. (DEVICE)
Error [122] c:\pbp\tests\cdtes~1.asm 108 : Illegal opcode (pic16f877)
IF I take the @ DEVICE pic16F877,HS_OSC out and put it as the first line of the program it does the same thing
If I take it out altogether it compiles ok but just won't do anything with the LCD.
I don't want anyone to write any code for me, I want and need to learn, however I'd really like someone to help please and explain what I'm doing wrong please.
I also tried changing the osc to xt but it makes no difference.
Has anyone any ideas? and sorry for asking for help for what must be to most of you a very simple problem, but I've spent 3 days trying to figure out what is wrong, as well as trying various combinations of code.
Oh Picflash v7.13
Microcode Studio ver 3.0.0.5
PBP ver I THINK it's 2.50C but not sure how to check.
