PSoC_4_BLE_SDCARD

userc_39563 Dec 17, 2015 4:35 AM

Hello,

I'm working on PSoC 4BLE. I want to store the data in SD card. So i'm using SPI as a emFile. I'm getting the folder created in my SD Card & getting the name which i'm putting there but not getting data in SDCard. What i need to do for getting data?

Thanks,

Chopra I am sending you a program that was in the 100 projects in 100 days on Element 14. It compiles with out errors but has a few warning. Also as I researched this I discovered that the SD card must be formatted for use. Also this is for the PSOC 4 so you may have to modify it for the PSOC Ble.

Also one last question why are you not using the F-ram on the PSOC 4 Ble? It is 1 mb in size.

Thank You Bob,

I have SD formatter & I formatted the SD Card. Yes i can store the data in F-ram also but for our project purpose i need to use SD Card so when we need data according to time we can take from SD Card. I'll check your project also. Can you please mine.

Thans,

Arpita When I tried to compile your program it failed saying FS.h was missing. This file was also missing "MMC_X_HW.h"
I don't know what that file does but the FS.h is used for the SD card I am sure. I don't have an SD socket to try this program but the missing files could be an issue.

Hi Chopra,

I was wondering if you have solved the issue concerning PSoC 4 BLE and SD card. I am currently working with PSoC 4 BLE and understanding the communication with an SD card using SPI.

Hello Rey,

I'm working on PSoC 4BLE & communicating it with SD card. I'm able to store all the values in my SD card.I'm trying to change the folder name according to time stamping so that day by day folder will be created in SD card with date stamping. So that if we want data of 13 jan we can easily fetch from SD Card.

Thanks,

Arpita
