How to safe to external memory

Other Hardware Storage
1

Hello,

I first would like to introduce myself, since I am new to this forum. I'm Niels, 22 years old and currently third year student of Industrial Design at the University of Technology in Eindhoven (The Netherlands).

To get to my project, I have a very short question, is it possible to implement an IC to my circuit to log data, I already have a circuit in which I'm able to log data to a micro sd card, though I would like to have a flash memory implemented in my circuit. I guess this will be possible and probably quite easy but what kind of IC is recommended?

Thanks in advance

Regards,
Niels

Hello and welcome.

I did a post about adding 512 Kb of EEPROM here:

Thank you,

Thus I could use these kind of chips to log data on, from e.g. a accelerometer or other type of sensor? Is it also possible to read safed data then?

Regards,
Niels

Niels, there are new technologies available - FRAM and MRAM memories, SPI serial, parallel, nonvolatile, fast, infinite endurance. You can write and read full speed. You may try:

Hi Niels,

I would advise an SD card to store data. Then you can read it on you PC/Mac very easily.

Those look quite interesting. But, since I only have experience with SD cards, are these easy to access in order to read saved data (*.txt file)?

Hi Rob,

Thanks but I already made a first prototype with a micro-sd but noticed it took to much physical spacing on my board.

Maybe this lib is useful - Arduino Playground - LibraryForI2CEEPROM -

Thanks for your help! Though, I think I should go with the good micro sd for now, but I will certainly use the information provided in this topic for further development of my circuit.
