Hello. I'm not using Arduino directly for what I'm trying to do. In this case I'm using Arudino just as a programmer to the ESP01 module I'm using. So, my goal is to be able to write a string to an eeprom chip (Microchip 24LC16B) and then, be able to read that same string an print it out to the se…

What you mean the eeprom? The eeprom is not getting any code to execute. There is no microcontroller there. :expressionless:

The Arduino Uno is only here to serve as a TTL-to-USB converter. Forget I have an Arduino here! The goal is to program the ESP01 so that it controls the eeprom chip!

Perhaps some of this goose-chasing could be curtailed with a simple pen-and-paper connection sketch?

[image] PsySc0rpi0n: The goal is to program the ESP01 so that it controls the eeprom chip! Don't you have that with simple writes within a page. I thought you were having difficulty with large block writes across page boundaries and managing the addresses for that.

Do you have any flexibilty on the choice of the EEPROM. The 24C16 is a bit of an oddball with its addressing scheme. I had trouble finding a library for it. And its an obsolete part now I think. The 24C32 is a more normal EEPROM, It only responds to one I2C address, and then the word address fo…

It is required that the communication protocol of the said EEPROM is fully understood before objective evaluation of the EEPROM results being delivered by ESP01.

Probably yes, but it won't happen today, because I'm not feeling very good today. But I'll do that later. [image] cattledog: Don't you have that with simple writes within a page. I thought you were having difficulty with large block writes across page boundaries and managing the addresses for t…

Sure, sorry for the huge delay [image] I'm trying to fix some bugs, because I think the reading function is still not complete and it is not reading from the correct place, in the first place!

Well, I have something that is not working but I'm not sure if it's the bugs or if some random data that is in the eeprom that is being read instead so I want to erase the eeprom. Is there any specific procedure to erase the eeprom or simply writting zeros to it is the way to go?
