hi all i have a asm file and need it converting to a hex file for a 12f629 chip
could any one do this for me
thanks again

marko

 

When you write the assembler instructions in the editor, the file that they get stored in is the .asm. After you tell the editor to process the instructions, the hex file is produced.

 

i got this asm code of a web site and i have no idea about codeing yet i'm learning so if some one could change it to a hex file it would be much appreciated untill i learn how to do this my self

 

I guess another way to put the answer is how are you going to program the chip, once you have the hex file? There should be an assembler available for your programmer.

John

 

Hey Mark, all u need is a good assembler like Keil..... u can find Keil at www.esnips.com and search for Keil...... version 8 is better


if u need any help just PM me....

i'm using winpic 800 and a jdm programmer

 

i have had a go at making the hex file from this asm file unfortunatly no
succsess
so acn some one do the trick for me i have attached the asm file
thanks

I copied what you posted, made a new project in MPLab 8.0, and pasted the material. There appeared to be some errors, and the asm code would not compile.

Some superficial observations: The file is made for the 12C508 and 12F675 You need to change the file for the processor you are going to use, or are you using the 12F675? I am not adept at assembly to debug the file quickly. So, you might want to download your assembler (like MPLab) and get the file debugged and working before trying to program a chip.

well i'm not as clever as you so if you could debug it for me i would be eternerly thankfull i got the sorce from and it is for a 12f629 acording to the site
http://homepages.paradise.net.nz/bhabbott/navlights.html
hope this helps you
thanks once again
ps i found errors with keil but i dunno what to do or how to make it into a hex file

 

as long as there are errors in the code the compiler wont make the hex file..... anyway below is the way of making a hex file using Keil (can be found on www.esnips.com and search for Keil. version 8 is better)......

in the file menu goto project> new project> then choose the ic> then make a new text file> then save it with the name and extension .asm> then copy paste the code u have>

after u've saved the file with the name and extension .asm then u need to expand the folder whose name is Target1 (its located on the extreme left corner of the monitor) then u expand it by clicking on the plus sign.... then u right click the source group1 folder and choose add files to group..... and then select ur file, the asm file.... click the add button and then close button

then open the wand button next to the place where its written Target1.... this button says options for target if u keep the mouse on it for a while..... open that button and in the ouput tab check create hex file.... then complie the program and u'll find the hex file present in the folder where u saved the project.....
