I'm a fresh faced newbie to Arduino but so far enjoying every moment of my involvement. I thought I would make my first post some good news, which is unusual for support forums
I would just like to share my very first experience with the LC Studio SD module, noting quite a few issues and complaints from others trying to get it working.
Using a Nano, and wiring up as per the Cardinfo sketch (using 5V to the module only), to my surprise, the module worked first time. Using a 4Gb Sandisk card (formatted FAT32), the sketch read the card and displayed all directories correctly. 8)
I will now test a few other cards to see what the results are.
I have LC Studion SD modul, also 4GB SanDisk card and Arduino Uno controller.
However, I can not write files on the SD card. The files are created, but the content is corrupted.
Have you done something to make this work? or it just worked...?
Some SD cards work. You are using the SD card out of spec and sometimes the input protection circuit will tolerate the extra current. It is random and with two cards of the same model one may work and one may fail.
You can never depend that the over stressed card will continue to work. A small change in supply voltage may cause a failure.
So what would be the solution? To change the module?? I have an urgent project until end of September, i could not wait for the new module more than a month.. That's why i'm trying to make this module work.
