emFile for use with SD card...
I am running the emFile_Example01 on PSoC3 Creator 2.2 while interfacing with the PIC18F24K22 MCU.
This application involves logging data to the SD card with the PIC18 being the main MCU while the PSoC3 is only used (for now) as an SD card data logger using the emFile_V322b data files.
I noticed that in order to write data correctly, the firmware for the PIC must be delayed least 100mS between write to the PSoC3 else data on the SD card can be faulty. I have read on the web that the average SD card delay-betwen-wrtie time is about 10mS. This is much more acceptable then 100mS.
Data between PIC18 and PSoC3 is via RS-232 at 9600 baud.
I believe that this is an issue with the emFile_V322b files. Please advise on how to make data logging faster.
p.s. if this matters at all which I don't thnik - my PSoC3 PN is: CY8C3866LTI-030. Again all is working fine but at 100mS delay between write.
