Achieving high write speeds with emfilecomponent

srihari.s Apr 30, 2013 11:04 AM

In get samples in real time and would like to transfer to SD card at 32KBps. When I go to resources and performance it shows when I buffer data of 1KB then there is a possibility that I will achieve this. I want to transfer only 256 bytes of data. Seems like it isnot at all possible with emfile componenet.

How do I achieve this speed? An example project if any one has will be very helpful or an explaination of how to build this project will be helpful.

Thanks

Here is a solution with much higher writing speeds -

The project does not contain any files, or I did something wrong?

Looks like author, whoever that was, took it off site.

Unfortunately the author does not respond to my requests.
Dana, you no longer have a copy of this project?

I thought I had saved it, but searching I cannot find it.

Sadly, not many examples with emwin and emfile.
I hope someone have a copy.

I downloaded the emFile zip file from the Segger, and tried if I could interface the SD card with PSoC 5. But the entire libraryu is C++. If any one has already ported let me know or let the forum know.

But the emfile library is already available from Cypress. Or do you mean you want to use the original one from Segger and check whether it is faster?

I wanted to see whether the Segger library if included in the PSoC Creator willl work fast or not. As previously said there are no additional example projects that will demonstrate the ttotal functionality of emfile component.

And also since the PSoC 4 is out and kit built is arduino compatible, many of the shields have SD card support. But the projects for AVR in Arduino forum has C++ files which cannot be directly ported to PSoC Creator.
