Only the chipselect needed to be modified for the SD library to work. Pear Merci Thank You Notecards Stationery. I am using an esp8266 and already have the SD card running and working correctly. This should be possible but I do not have the programming skills to get it running. Only reading the values is enough, I am not looking to modify the CID. If you're interested, you can check out the SD Card Association's specification (the 'Physical Layer') here for more info on how the CID information is gathered.Hello I would like to be able to read the serial numbers of SD cards using the SD.h library. If you're deadset on getting the CID info and don't mind using additional hardware (~ $10), you could buy an SD card breakout board and connect it to an Arduino or whatever, then you'll have access to the pins and you can write your own code to read the CID data.Ĭredits to this answer, which is what my answer is based off: send a custom command to it over USB), but AFAIK this kind of thing doesn't exist.
