Hello,

I am new to map lab i want to know how to start it...
please help me to start with PIC 16f676 with blinking LED like 555 chip...as table.


thanks

 

Take a look here under development tools
http://techtrain.microchip.com/webseminars/Quicklist.aspx
Edit this may not work. Use this
http://techtrain.microchip.com/webseminars/Archived.aspx
And select Category development tools
Sorry go here then look under development tools. This is not my fault the microchip web site is mess for the time

checkout the tutorials on googlium electronics website, they were brilliant when i started and includesorting out linker files etc in mplab. sometimes they dont open properly (not sure if its my end or there server but if the tutorials are down let me know and i might be able to scan a hard copy to email you

cheers harry

 

the first thing you do is create new project.
this will allow you to select the chip you using.
from there it will open up new windows and other such things i havent figured out myself.

I don't find there any MAP lab tutorial..
please help me to start.

after that what to do..?

Program to you drop
But before you do so take a look here

Hi,

I want to make a program which will glow LED on pressing external switch...please help.

 

C or Assembler

 

Only assembly...

 

Did you manage to write a program blinking a LED?

 

Bcf status,rp0 'bank zero
movlw 00h
movwf porta

bsf status,rp0 'bank 1
Movlw 00h
movwf trisa

bcf status,rp0 'bank 0
start:
movlw 00h
movwf porta
call delay
movlw 0ffh
movwf porta
call delay
goto start

delay:
Movlw 0ffh
movwf 021h
dcrfzs 021h,0h
return

 

How do you set the configuration bits. Do you set them in MPLAB or not at all. I am asking because this is very important. You should also for your sake set this in the code. And it is also very hard for other to help then this information is not in the code.

 

How do you set the configuration bits.

sorry??

Do you set them in MPLAB or not at all.

I am using OSHON simulator, can we do simulation in map lab if yes please tell how?

 

delay:
Movlw 0ffh
movwf 021h
dcrfzs 021h,0h
return

This should be:

delay
movlw ffh
movwf count   ;can't put this inside the loop
loop
decfsz count, F   ;using W or F instead of 0 or 1 is much clearer
goto loop
return

This will still be too fast for the eye to see if your oscillator is 4MHz

You can declare variable names at the start of the program, it's much clearer than just using numbers for the files:

cblock 0x20
count
foo
bar
....
endc

 

Is MAP lab MPLAB?

You can get several free compilers for the PIC processors, which run under MPLAB. I think it would be much better if you wrote your code in C rather than assembly.
