pic16c54

Hi,
I found a code in Microchip's site with extention "asm".
But I dont know how to convert it to hex file so can be put in pic16c54.

What program do I need for converting?

inside the file is like:

; This program is intended to run on a 32 Khz watch crystal and connects
; to four multiplexed seven segment displays. It displays the current
; time, alarm time and egg count down timers. There are switches that
; allow the user to set the alarm, timer and clock functions.

As far as i'm aware of, there's no program to translate from ASM to PBP. The only thing you can do is to learn Microchip's asm and do your own conversion.

There's some user here that know ASM but i feel that they won't do the whole translation... or not for free.

For what i read in the program header, you can do it easily. If you want to have my easy 1/2 hour code writing... Use a 12FXXX PIC serie(or whatever else), a DS1307 RTC and a 7 segment driver IC like MAX6958... not the cheapest solution but...

It is strange that Microchip gives people the code which is useless then.

Use MPLAB to compile it, it's also free from Microchip.

It's not useless... this is Assembler... download the FREE MPLAB software from the Microchip website... it contains the Assembler needed to convert the .asm into .hex which you can then use to program your PIC.

I finally succeed making hexfile using mplab but only after deleting four lines from the asm code.Now I am not sure if it will work.
I will try..

hello
the clk8.asm files is readily downloadable from microchip as part of AN615b and the same has been used by me ( of course i have locally compiled) and the same is working FINE.
Here one thing is to be noted . the common cathode wires coming from RA 0-RA-1 ,RA-2 and RA-3 may require rescheduling. Otherwise the display gets jumbled.

However PIC16C54a is an OTP device. Perhaps it is better if you can try a newer version PIC16F54 instead as this s flash programmable, by managing a suitable programmer

Thus, Necati may very well use it. ALL the best

I only wonder whether some has tried to modify this software to work on PIC16f84 and i request for help in this direction.

Hi, Sarma

Seems migrating from C54' to F84' is not so easy ...

first, have a look to Appendix C from 16F84 Datasheet : main explanations are here.

BUT ... if the programmer has used its own tricks ... that can be a bit harder !!!

I experience it on another clock program ( DCF Berliner Clock ) ... "basic" clock works well, but I still can't get the LED multiplexing work properly ...

it relates to Writing to the PC ... but where ???

good luck

Alain

hi, necati

hope you might have adopted the clk8.asm by converting the same to hex code

if so desired perhaps i could send clk8.hex copy

Hi all and Necati in particular,

I am now able to modified the an615 (clk8.asm to be able to work on 16F84A and i have two versions-- 1. with display OFF after 8 sec and 2. One to contiuously display-

i could send the .HEX file if someone wants.

Enquiries are welcome.
