KwikStik working with SD card

Hi,

 

For those who want to use a SD card with kwikStik we are pleased to announce our very first emulated SPI driver for SD card. We emulate the SPI pins trough IOs.

 

Now it is possible to access the SD card of the KwikStik kit. It is not so fast, but works.

 

Source code can be download here. We only tested it written into the FLASH (not in RAM).

Regards,

Gustavo

Hi,

 

Kwikstik has test pads for SD card connector pins.

And unconnected SDHC0_D0~D3 are all connected to TWRPI or PCI connectors.

So I think we can enable SD card mode access by solder the test pads to that connector pins and set wrongly connected D4~D6 as input...

 

Regards
