Supporting a SD card



  • I want to support storing the data on cheapstat on a SD card, so the results from each iteration are stored on it in a csv format, which can be taken out of the device and the data can be read by a computer, any ideas on how that can be achieved?

    Unfortunately, I don't know of any easy way to do this. There is a little flash chip (IC4) which is there to provide external memory which isn't actually used at all. It uses an SPI interface - like and SD card. If you don't include this chip you might be able to hack in and SD card in its place. Connecting wires to the pads maybe - it would be a bit dicey though. You would also have to modify the firmware to read/write to the SD card.
