SPI to SDHC flash cards

[pnielsen]

I am using Cypress PSoC 3 and 5 MCU'S. Can anyone tell me of a good resource to understand how to read and write correctly. I would like to store data on the card and later retrieve this data possibly using a flash to USB converter.

You can refer to SD card product specifications, e.g. from Sandisk https://www.edaboard.com/threads/159764/

You did not mention which MCUs you use. What are they and do you have a preference?

The basic interface and driver code are not difficult, however using a FATFS can be challenging depending on the version.

Here's a few tutorials:

If you have a preference as to which MCU you wish to first implement the SD interface and FATFS, let me know I have other examples.

Hope the info helps,

The original post refers to Cypress PSoC3 and 5, using 8051 and ARM Cortex M3 core respectively.

Thank you very much for the excelent link. I am going to use the mikroelectronic flash card holders for development.

Thank You,

I stand corrected, I misread the original post as meaning PSOC3 and 5 other MCUs.

Here is tutorial covering the interfacing of SD cards with 8051 for your PSOC3:



The tutorial uses the "FatFs Generic FAT File System Module" available from the link above.
