TMS320F2812: SD card Interface

Supratim Manna

Part Number: TMS320F2812

I am using a F2812 based experiment kit. And my goal is to store the data, obtained from the ADC, to a sd card in by making a .txt file. Now while doing the hardware interface of sd card with the F2812 processor what type of sd card i should use? Is there any specific sd card module for F2812? I have an arduino sd card module ( Photo is attached below). Is this compatible with F2812?

Hi,

As far as I remember, this board is not suitable for 3.3V C2000 controllers (My Intern had made this mistake). This board shifts MOSI & SIMO levels far below 3.3V as its supposed to shift 5V signals to 3.3V ones. You'll have to purchase the one which supports 3.3V signals directly.

Gautam

thanks for your reply.

Can you recommend any such micro sd card module which will be better compatible with TI processor?

I am using a 16gb class-10 micro sd-card for the interfacing and i am facing some problem while initializing. Is a 16gb class-10 micro sd card compatible or not ?? Is there any certain limit of the sd-card's memory size ?

I'd tested with 32GB Class 10 also, the only catch here being the sd card needs to be formatted as a FAT system.

No one mentions the maximum memory limit. So no official information as such.
