How to transfer pic codes to other pics ?

[XXL]

I'm trying to setup the saa1057 PLL on my pcb design, iv got the hex code for the pic from zozo's board which is only for pic16f84, but I have a shitload of pic16f88's that id rather use up than buy new pics. How would I go about it ??

[Albert H]

Unfortunately, it's not trivial. The memory map for the '88 is very different from the '84 (and the opcodes differ too, as I remember). There are a few conversion programmes, but usually for '84 to '628. I'll have a look and see if I've got something for the '88

Yeh even 628a iv got a few of here but thought 16f88 would be the most compatible.

Zozo used the freely available code for Saa1057 that's published on pira.cz web. There is also the source code.
I'd take that source code, paste it in a new project in MPlab (Microchip's PIC development IDE) and compile it for your target microcontroller.
You will need to configure additional "fuses" in your newer device.

Yeh I’m trying to learn how to code it but starting from a complete novice with C, I’m totally lost. I understand things like R & N registers for the saa1057, but I don’t get how to tell the microcontroller that.

If you rebuild the pira.cz code you'll need to get hold of a copy of the old mplab. The new mplabx has totally different assembler syntax so the old code won't build

Can you try this hex file, i compiled the source code for the pic 16f88

Anyone got the hex for the smile board. For the PIC16F628A

[RF-Head]

No it's custom made and not public
I made the design years ago and sold it to someone here on the board

Could you do one for the 628? Albert mentions there is a conversion for 64 to 628, but rf-head says the hex for 628 was custom and sold on this board, if u could u will be loved

[whitenoise]

I second that , although I will only goes as far as a man hug

Can you place a picture of the smile board ?, if it's the same as the ZoZo then you can try this code, i compiled the source code for the 16f628a,

Why do you need the hex for that ? You get it with the kit when you buy on eBay. Only reason you would need that is if you have tried to copy the design. There’s literally no need to reprogram it because you can change the frequency with the buttons on that board.

[LeeCavanagh]

Probably fried the chip , it’s easier than you may think.
I would quite like to try my own design using this pic, and would also have just up and down button ,maybe another for save but that’s optional
I’m willing to try learn the assembly lang, but even if someone can’t provide an example of one (AI not have kinda started me off , miraculous those things) then if someone can just provide a working hex for 628 , that chip and two buttons are not owned but anyone and this forum is all about sharing learning.

Oh @pukje62 is here , how are you freind

[yellowbeard]

Freddo the Dutch fella had a design for that PIC and PLL back in the day, bad news is it has FOUR buttons, but there is a hex file...

It's on the PIC16F628 page.

[LeeCavanagh]

Thanks will look into that
Do you know if there was ever an asm file ? Then I could edit it and recompile for pins functions

[thatpirateguy]

hex the planet get the the file out
