Hi Mark,

In your post to this thread on 9 September you talk of further developments for Graphics LCDs.

Will this library work with TFT devices such as Olimex LPC2478-STK board, I will be over the moon if it does?

Thanks, Roger...

Hi Mark,

Resolved with some embarrasement on my side :-)

SUPPORT_TFT was defined, but I had commented out the #define SUPPORT_GLCD at some point in my debugging.

Only slight issue remaining is the one shot only at presenting the TFT image on the webpage.

Many thanks for your assistance with this.

Cheers, Roger...

Hi Mark,

That did the trick! Now why didnt I think of doing that. I was also uploading the wrong set of pages which wouldn't have helped.

I now am able to browse all pages and change configuration except the upload image to TFT is not working. The image uplopaded does not appear on either the web page or the hardware. I will try to debug this further.

Thanks heaps for your assistance.

Cheers, Roger...

Hi Mark,

Not working for me on my Olimex LPC2478-STK or the simulator as per my other post.

On the hardware, it is mostly running except the webpage has the uTasker background and the forground text is garbage and hangs my browser.

FTP to the board produces the following:

C:\Documents and Settings\Administrator>ftp 10.10.10.100
Connected to 10.10.10.100.
220 Welcome LPC23XX FTP.
User (10.10.10.100:(none)):
331 Enter pass.

226 OK.
ftp: 96 bytes received in 0.17Seconds 0.56Kbytes/sec.
ftp>

If I upload via the DOS Copy_All batch file the upload appears to be happening, but a ftp>dir shows no change in content on the board.

I hope that we can solve this one as I am dead keen to get this running and findout all the good stuff that uTasker has to offer.

Cheers, Roger...

NXP^TM LPC2XXX and LPC17XX / Issue with uTasker on Olimex LPC2478-STK

Hi,

I am having problems getting uTasker to run on my Olimex LPC2478-STK board.

On running in the simulator following Marks directions in the NXP LPC2XXX Tutorial all appears to be going well until I get an exception thrown when I try to upload the Webpages via FTP using the DOS Copy_All batch file.

The following exception is thrown at the following code in LPC23XXSim.c when the *(unsigned char *)0 = 0; is executed as it is trying to write to location 0x0000000. "Unhandled exception at 0x00474fe3 in uTaskerV1-4.exe: 0xC0000005: Access violation writing location 0x00000000."

                if (iOldLineBlank == 0) {                                // check that we only write 1 to non-blank lines
                    iLineLength = 0;
                    while (iLineLength < FLASH_LINE_SIZE) {
                        if (ucNewLine[iLineLength++] != 0xff) {
                            *(unsigned char *)0 = 0;                     // writing non '1' to a non-blank line - signal so that this can be corrected
                        }
                    }
                }

Why is this code writing to memory location 0. The comment is suggesting that this is to signal an error so that it can be corrected later.

Any assistance here would be gratefully received.

Many thanks, RogerH
