What about the status of this project ?

[jube]

hlide..........

will be posting the example driver code i used and general data format in next couple of days, will then assemble some "dev" units and distribute them to interested software developers, will take another week, then still on target to offer consumer units in about 2.7 months. At the moment sourcing EXACTLY the right size touchscreens is proving a problem, but will sort it ! So suppose its going well with all the usual unexpected delays !!

[jean]

i was thinking that i could be of help providing a library of mine performing character recognition via a small ANN: it's small in size, has a small memory footprint, fast, robust....think about it

[jube]

jean....... wow that sounds cool!!!, you still running a phat? , the dev units for phats are well delayed, initially was'nt going to support phats at all but public presseure forced re-think !!!

[Wraggster]

hey jube do you have a blog/website where you can post updates on this project, would be good to hear the progress on this.

yeah...i was thinking to pass to a slim before ta88v2 hell arrives here in europe, but 60 euros of difference for 32Mb of ram and a tv-out are an exageration (i mean...selling my phat and re-buying a slim will cost me approx 60 euros)
What do you exactly mean by "dev-units"?

[moonlight]

[jube]

jean............ im making and distributing ( free to interested commited developers ) about 10 dev units, these will be functionally identical to the final production units except very "rough" in terms of the hardware ( stick on screen, trailling wires etc ). Its going to cost me, but im hoping that by the time of the launch there will be a number of hombrew apps and games supporting the screen. Im going to be taking PM,s from interested developers today or tomorrow sometime and hopefully shipping the dev units to people by end of week, thats why asked if you were running slim, cos phat dev units not ready !

No blog im affraid, have zero idea how to go about one !!, who hosts that kind of thing ?

Nice, bu tnow I can only see the thumbnail.

Good progress :) Phat units not yet ready?

jube, youre going to make it a commercial product though it will only work on Homebrew/CFW? I mean, is it legally all right?

[hlide]

[jube]

no not worried about the legality as hlide pointed out its damn sight less contraversial than something like pandora. Yes V1 works only through the sio hence is only a cfw product that is going to limit the customer base big time but since the main motivation is not to make money, but to get the screen out there supported by devs, as long as i break even not to worrid :)

[jube]

hi guys, her is another 2 vids showing app have done, will post the code in a bit, BUT DONT FLAME ME !!!!!, am just starting on psp code and the code is shit!!!!! not exactly text-book c!!! ( coming from a microcontroller background where even function calls are a no-no when they eat up your stack!! )

[jube]

thats the source to the osk that video'ed, posting it to let developers know how the serial data stream looks like, its all very simple, and a little derivative but hey just starting!
this bit uses jeans sio prx but its just as good using the sdk call ( at 14400 obviously ! )

[hlide]

Please, Jube, always use tag code "[code/]" to put a code source.

example :

[jube]

hlide.......... edited it, thanks, looks much better :)

[jean]

why OSLib??? no big deal having a whole graph library if you only have to do a pair of blits per cycle...moreover, the last time i checked OSLib, it was closed-source.
Some (very)small guidelines/advices:
in byte2word, no need for an in-memoy temp variable, let the compiler hold midvalues as registers that's way faster if you use it frequently.
so:

[hlide]

[Phantom8]

jube, great job! This looks very promising. You have added 1 of the most important features that Sony missed out. I think many of us will like to know how will the final product fit into the PSP Slim. Does the mod fit insides our PSP, or stick out like the one you've in the youtube video? If it fits inside the PSP, does your product come with a replacement faceplate?

[jube]

jean........ hlide...thank you VERY much for your kind words and advice, its good stuff!!! will maker those changes when i get out of the hardware world!

phantom...unit will come in 2 flavours, a clip-on add-on, and an internal modification, the internal mod will include a custom molded top casing which accomidates the extra 1.7 to 0.9 mm touch screen. The clip-on should come in at a reasonable $60-80 ( break-even price ), but the internal mod will be horrably expensive!!

You cant see much cos of the camera, but the second videos are of the internal mod ( dev unit ) BTW. video is with my dev screen which by now is knackered! so response not that good!!

[kralyk]

great work jube!

(just to say, in future releasing some sort of lib for the touchscreen ad-on for others to integrate it into their homebrew would be nice, just saying, you probably plan to do it anyway dont you...)

btw. how much the you estimate the touch ad-on to cost?

[Phantom8]

jube, it's good to hear there will be 2 versions. I'm more interested in the internal mod, but this of course will depend on the final pricing. I understand making custom mold would be extremely expensive. You may even lose money if you don't sell a lot of units. To me, determine the pricing would be difficult. If the price is too high, you may not be able to sell many. If it's too low, you will need to sell a lot to even break even. Have you considered to sell you design or partner with other companies, such as neoflash or divineo? This could lower your risk.

To set up a Sparkfun 4wire resistive touchscreen controller transmitting via SIO RS232 to PSP:

3 chip circuit
<<3—3 chips are all you need for this circuit. The ADS7845 handles the analog functions and the
PIC performs the sequencing, scaling, and messaging formatting. The MAX232 handles the RS-232 level
shifting.>>
http://www.circuitcellar.com/library/print/0100/dahlin-114/f3.htm

Pic circuit
<<6—Four of the PIC’s
digital lines are used to provide x
and y voltage gradients. A single
analog input is used to determine
the contact point by measuring
the pick-off voltage in both the x
and the y planes.>>

http://www.circuitcellar.com/library/print/0100/dahlin-114/f4.htm

or

3 Volt one chip controller
<<The processor as interface is the Tritec
TR88L811, a dedicated 4-wire touchscreen interface device. It handles
all of the touchscreen scanning, touch detection, and message
formatting chores. The 3-VOLT device was originally developed for
the PDA industry.>>

as explained in
http://www.circuitcellar.com/library/print/0100/dahlin-114/dahlin114.pdf


or something ready to work with 5 Volt like
<<4-Wire Resistive TouchScreen RS232 Controller (SLT-TP05-RS232).>>
with software for all OS and PCs, included Linux and DOS.

Any comment about setting up a Touchscreen controller for special applications for PSP?

[jube]

yep all of the above sound good, for a phat that is :)

[jean]

[jube]

jean has about summed it all up, have very little to add, except the sparkfun screen is too big, by 1.2 mm, catches the dpads on both sides :)

[jean]

uhm...sorry if you already told me and i don't remember, but.... what touch-film are you using? can you provide a link?
