hello there

why i get 13 errors when i use from MPASM to convert this ASM file into HEX file?

heres the ASM file

but i get 13 errors???!

this hex is for a 3 led flasher circuit based on 16F84

Post the actual MPASM output with the assembler errors

here's the error i get:

here's the error i get:
Error[105] C:\DOCUME~1\MOHAMMAD\DESKTOP\ST001.ASM 24 : Cannot open file (Include File "p16F84.inc" not found)
Warning[224] C:\DOCUME~1\MOHAMMAD\DESKTOP\ST001.ASM 72 : Use of this instruction is not recommended.

These are the only real errors. The other errors are caused by the first one.

The main problem is the assembler cannot find the include file (p16F84.inc) and so doesn't know where all the special function registers are. The reason for this is probably that your MPLAB is not installed correctly. Try reinstalling MPLAB. The file it is looking for is in C:\Program Files\MPLAB IDE\MCHIP_Tools

The second error (really just a warning) is because you used the TRISS instruction. Microchip want to phase this out and so recommend that you write to the TRISS register instead.

HTH

hi

i reinstalled my MPLAB and even downloaded the only SPASM but i have the problem yet...

here's the MPLAB adress C:\Program Files\mcc18 and it seems there is no MCHIP_Tools file there?!
i can only see the 18xxx files there????!

 

[Pommie]

If you have installed MPLAB IDE V7.2 from **broken link removed** then you should have a folder called C:\Program Files\Microchip\MPASM Suite that contains the include files.

HTH

Mike.
P.S. just in case you don't want to download the (31 Meg :shock: ) MPLAB then I've attached the 16F84 include file. You should be able to put it with the 18xxx.inc files and get it working if you are using MPASM.

hi Mike

wow, i put your attach into my MPASM file and it worked for 16F84A just fine thanks for it.

i dont know why this file was not into it originally?!

i downloaded MPLAB (version 3.90 i think)but i could use from its MPASM only,and now i see it had a problem

i dont like to download 31Meg so...
do you know which kind of compiler is the best for C lang?

thanks very much
