datalogger, KwikStik, SDHC_LDD with no RTOS

Hi,

 

I'm working on the simple datalogger using KwikStik board and CodeWarrior. I'd like to write some data from ADC on my microSD card (.txt or .dat format). Is there any simple way to implement this without using any RTOS (the simplest continous datalogging using SDLH_LDD) on KwikStik? I've tried to import Elm-Chan's FATFs to my barebord project and modify diskio.c by putting functions generated  from SDHC_LDD component in it to provide low-drive handling for higher file layer. I don't know if it's enough to run  SD card or if there is any simpler solution. It seems that I can't even mount the logical drive. I've tried Erich Styger's components but all of them require other components, such as FreeRTOS and it's difficult to configure the whole project. Any  sugestions would be very helpful for me.

 

Regards, 

 

Marcin
