SD Card Lock\Unlock via SPI


Curious to know if it is at all possible to use an Arduino to read and write SD card CSD registers, specifically the TMP_WRITE_PROTECT and PERM_WRITE_PROTECT registers.

Recently a project was completed using an ATmega328p to modify these registers, the project page is here:

What would be nice is with an Arduino incorporate a number of buttons or switches to modify the SD card CSD registers to lock and unlock the device.

Any thoughts or guidance?


Anyone care to take a swing at this one? I would be willing to fund an individual to assist with this implementation; feel free to PM me if interested.


The Gigs and Collaborations section might be a better place to ask, if you're looking for somebody to work with/for you. (You're right - most people would expect to be paid for doing work for you.)
