Hi!
I have a boiler system that uses a FAT16 formatted SD card for logging runtime parameters. I'd like to monitor the system online. Data is written to the card every 5th second. I have three different aproaches:
- Use a SD Card, a SD Card reader, a latch and a timer. The timer switches the SD card from the boiler SD card slot to a USB card reader for 20 seconds every 5 minutes.
- Is there a USB cable with a SD Card PCB in the other end that could be used to interface the SD card slot on the boiler? The computer could then "emulate" a SD card.
- Is there any data logging tool that could log the SPI traffic to the card?
If you have any input please let me know!
Regards, Torgil
