Im using an LPC 43s67 for data logger application.

I have to collect data at 1000hz frequency and i am able to do it.

I write the data to sd card sector wise, without file system and it takes about 4ms for 512 bytes using .PFA my code snippet

 

Since the sd write takes 4 ms I will be missing 4 sensor read cycles.

So i wanted to open the sd card once in infinite write mode and then just pass data to the fifo, thereby consuming least time.
