JPG PaulS Guest. Re: Problem for reading and writting I2C Eeprom 24c02 6. Read this before posting a programming question Don't use "copy for forum" in the IDE.

Just select the code, copy it, and paste it here, inside code tags. Please post technical questions on the forum, not by personal message.

Thanks for the advice. I modified it. Yes it looks much better. Best regards. I can't see anything obviously wrong. Hello Nick It gives : I2C scanner. Found address: 80 0x50 Done. Found 1 device s.

Found address: 80 0x50 Found address: 81 0x51 Done. Found 2 device s. But when I try to write and read, there is only in each Byte. In the readData function try this instead of endTransmission : Code: [Select]. Don't send me technical questions via Private Message. Unfortunately, no change El Supreremo!

Code: [Select]. The 24c02 only has bytes. It only uses one byte of addressing so you would have to address it like this: Code: [Select].

From the datasheet: Quote. PaulS; I'm just using a Sketch found somewhere on the web. And I'm not a programmer, so till now I've been mostly copying different pieces of code and modifying some part, then look what was happening. You are talking about 2 Bytes of address that should be replaced by a only 1Byte address because the 24C02 has only memory blocks. So I think, you might be talking about something that has to do with this.

Is that right? I hope I'm clear enough as I'm a beginner and English is not my first language. Many thanks for your help. Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Sorry, I'm guilty, I haven't properly done the modification.

I haven't neutralised the "Wire. Here is the code and now it works great!
