9s12xge128 with emulated eeprom

JohnnyP — Wed, 25 Oct 2017 01:19:44 GMT

My product is based on a 9s12c32. The user interface is old school, using pots and dip switches.

It's time for a redesign to make it pc compatible, so I need to add EEPROM.

I'm looking at the 9s12XGE128, which uses emulated EEPROM.

How hard is this to use? How many registers need to be set up to get it going?

Hi John

My colleague ever made demo code of XEG128 emulate eeprom.

See attached.
Hope this helps.

Have a great day,
Jennie Zhang

Jennie:

Thank you for the project files.

I use assembly language. The code is in one file.

I will try to figure out your main.c code and convert it to assembly.

Ok, thanks.

unfortunately I don't have same assembly code.

This need to be converted by user self.

Have a great day,

Ok. I don't have any of these on hand yet, but I'll post the code when I get it figured out.
