Hi Mark

What a lovely day. :D
Have just tried your code modification and what a differences.
Instead of 6Kbyte in download I now get 160K byte.
It was defiantly the kind of improvement I was going for, so thank you for the help. :D
Keep up the good work.

Best regards
Steen

Hi Mark

Thanks for your reply ;D

I have read the short explanation of the problem and think that it can be compared to the HTTP server case you mention.

The reason that I mention ask this problem was that I was expecting the same performance for up/down load and was interest in knowing if I was doing something wrong now that I was modifying the code to support SD card.

is the speed an issue or just an observation?

Well yes it is an issue, my basic idea with the FTP connection, was to use a standard way to transfer files between the system and a PC, and in many cases will the settings saved to the system will have to be read out from the system again later.
I don’t fully understand the window buffering, but do you have any ideas on how difficult it is to make the changes that increase the speed without using to much memory?

Hi,

I have tested the FTP server in the uTasker and found that when i upload to the unit i get a transfer rate of 130 K byte/s.
But when i try to download the same file i only get a transfer rate of 5 -6 K byte/s.

The data are stored on a SD card, but even when ii try not reading data from the SD card and only send a "empty" buffer I get this low connection speed.

Have I any of you see this on yours system ???

Hi Mark

Thanks for you quick reply.

I have had the chance to test it today and it works perfect when using PIT1. :D

Ones again thanks for the help.

Hi

I have been trying to get a FAT system up running on SD card with good luck.

Now i try to get this into the uTasker, but have got a basic problem....
The SPI driver needs a 10 ms timer to get the timing/timeout right to the SD card.
My problem is now that the RealTimeInterrupt interrupt are only running when the system is idle, and I what the timer to count when in a thread as well.

Can this be done?

Regards
Steen
