Hello,
First of all. My Arduino Pro Mini reads and writes data to an SD card via a passive reader (sniffer like spark). I use a divider bridge to reduce the voltage to 3.3v (except Miso). It works perfectly. I am now looking to connect my arduino via my sniffer to an SD card reader connected to a PC. Has anyone already done this please? I have MISO which is output so passes through a divider bridge. So, do I put MOSI live or leave my divider bridge? Thanks in advance for your help.
How is that SD card reader connected to the PC?
Via a USB Card reader.
So where want you to link in?
How are you writing if you are using a passive reader or sniffer?
I would imagine that the card reader SPI clock is pretty damn fast. Possibly faster than your Arduino can handle.
Hello,
I"m writing to test and only when the card reader isn't connected to the PC. It's the mode "Master" for the Arduino.
My goal is to intercept data when the PC writes on the card.
The best would be to recover the files recorded on the card but at least know if a new directory and/or a new file is created.
If you have an idea or another method, that would help me. Thank you.
