    touchscreen worked for a few minutes

    Not understanding what the middle clip of the top is? Is this near where it meets the base, or somewhere around the edge of the display itself? Nothing seems to be popped open or out of place.

    touchscreen worked for a few minutes

    I wasnt doing anything at the time, I tried it right out of the box, tried to get wifi up, then decided I should plug it in and let it charge for a while. Came back found that the round things in the middle could be used for the mouse too played with those for a bit and at some point wanted to...

    touchscreen worked for a few minutes

    cannot calibrate because it does not recognize anything touch related anywhere on the screen (how do you exit the calibration without completing it btw?) I rebooted, repowered, reflashed, all of that no change. yes the nubs work for moving the mouse around and selecting things. Left it at...

    touchscreen worked for a few minutes

    The touch screen worked for a few minutes and that was it. Nothing now, is there some manual switch or software driven touch screen enable or is this unit broken? If broken what are my options?

    Leapfrog Didj Homebrew

    Just received my Didj today, hoping there is a way to develop for it. $45 US on amazon. Anyone gotten anywhere with the source or filesystem or serial port?

    GP2X Fixed Vs. Float

    This is a C version of add from an older gcc, looks like the newer gcc's use hand coded assembler for each platform. Looks like you can get a little improvement by removing rounding. overflow and underflow would still require an if then else (not sure if I see overflow and underflow in the C...

    GP2X Fixed Vs. Float

    So I did misunderstand, sorry. I think in bits and hex not decimal (makes it very hard to balance my checkbook and my timecard). One of the TI DSP documents talked about the float format they use, and even had detailed instructions on how the add and multiply worked. shift this operand or...

    GP2X Fixed Vs. Float

    Single precision has around 23 bits of precision with a sticky bit or two for rounding. double and extended of course have more (and use an assumed 1.0 bit which gives you one more bit of precision, single for some reason wastes that bit). You can certainly do a hybrid where you use say a full...

    GP2X Gp2x Boot Procedure

    I use the modified uboot that allows loading from the sd card, my non-linux, non-os binary is loaded into ram via uboot and executes. Is this what you are talking about or are you looking to replace uboot itself? Uboot is way too bulky for my tastes, but it works and not a project I wanted...

    GP2X Porting Applcations In General (makefiles)

    I seem to remember that borlands make was more "accurate" or unix like than microsofts nmake. but borlands doesnt work all that well anymore under the NT derivative command lines (NT, WIN2K, XP). Nmake works just fine. I also live by that keep it simple approach and you can easily move from...

    Is It Possible To Have Standard C Libraries On The 940?

    Download this: http://www.gigasize.com/get.php/43308/arm-20060802a.zip And there are examples in there (As well as a compiler to build them), I am pretty sure I have a malloc example in there (or perhaps every one of them does a malloc and then prints hello world first). Near the top of...

    Is It Possible To Have Standard C Libraries On The 940?

    Sure I use memset, memcpy and malloc on the 940 no problem. I use newlib and take control of _sbrk (and all the other platform specific functions, file i/o, etc). Just like any other embedded situation you have to manage your memory space, decide where the heap and stack are, etc. Recently...

    GP2X 940 Unstable

    Sorry was picking up bits and pieces and not the whole picture. Saw the infinite loop on the 920 assumed you were done using it... I have not had any problems running the 940. But I intentionally hose linux and the 920. Before I started doing that I was still not having problems, the 920...

    Are you disabling 920 interrupts after starting up/switching over to the 940?
