Eeprom reading and flashing. I’m not very happy with that code.

Where did you find it? Which Arduino board are you using?

M datasheet & applicatoin notes – Datasheet Archive

The Arduino Uno with that code should be okay. I don’t know how to help. So it is hard to tell. Is there a status register that you can read? I took a look at the website of ‘ST’, but didn’t find example code how to use it. When direct register writing is used for faster data transfer it is harder to check what is wrong.



Once that is working, you can add everything else. You started with this I think: The M is not normal. Did you read the datasheet a few times?

It has special startup conditions, or it won’t even work. When I look at the datasheet at this page: Can you determine which you have? I can find a few different versions.

Eeprom reading and flashing

I assume the brand of your chip is ‘ST’? I want to be sure which chip it is, to be sure to get the right datasheet.

Looking at picture, this might be an older version, without the extra things. I’m sorry, but I think we are not even half-way there. How can you tell datasheett you are reading the chip? Perhaps you are reading nothing and that results into 0xFF.

Ok, got some new things and got it working with a software named ponyprog, but i would like to ask if i can manage to do a “my own program” that uses arduino to read from the eeprom because with this it doesnt uses arduino only some resistors and a serial port or maybe configure the arduino to work with this software but i dont think that it’s possible any ideas?
