Tungsten C???

[rpgxerofl]

My friend is planning on getting a Tungsten C and I want to know If LJP will run on it. I read a prior post about button lag and I am curious if this has been fixed, Please let me know.

[metaview]

Nope, the keyboard (except some keys) on a TC can't be used for LJP, the screen isn't hires+: I would rather recommend a TX (if WiFi is important) or a Treo 700p/680 if you want to have a full keyboard. OTOH you could use a IR keyboard or a BT gamepad in LJP on TC soon or even a PC gameport to Palm adapter.

The keypress slowdown is very annoying, but it's still much faster than a T|E at 180 MHz. That I'm thankful enough for.

I also found out that the use of an IR keyboard can bypass the slowdown. I'm thinking of modding one into a gamepad just for this purpose...(now, MetaView, when are you going to add IR keyboard support into LJP since you got the source working? I know you're busy on Shadow3D and all, but LJP is probably THE program I want to have IR keyboard support most!)

It's a shame that no one seems to be able to find how to improve the code, for instance by hacking in the Treo thumbboard API-particularly since I prefer the T|C's thumbboard by far over the Treo 700 models.

Oh, and about BT gamepads on a T|C, I just don't see that happening considering that I know of absolutely no way to get BT on one. SDIO cards certainly don't work(lack of Palm OS drivers). Maybe it can be implemented through the Universal Connector, though...then again, nobody really cares about the T|C now. What a shame...

Well my friend was getting a great deal n the thing for $45 and wanted to know if you can use the physical buttons, Nav,calendar,etc. for emulation. Also I heard that using lightspeed solves the problem, can someone please tell me how gameboy colour games and NES games will react to the buttons? Thanks

[namelessplayer]

Only 45 US$? I had to pay 126.25 for mine! Why do I never have this kind of luck?

NES games work great with the app buttons, and there's no slowdown if you overclock to 531 MHz-even if you enable sound and smoothing!

I don't play GB games, just NES, Mega Drive/Genesis, and SNES. (Or I would if it weren't for the slowdown...where's my IR keyboard support?)

The main problem with the thumbboard, if you're wondering, is that LJP cannot differentiate between the keys. Simply put, all 35 keys act as ONE button. Not very efficient...

[rpgxerofl]

He doesn't plan on using the keyboard for the games, are the keyboard keys responsible for the lag or are the actual App keys to blame, If it is the actual keyboard are there any patchs for it or a way to disable it to play LJP. Also will overclocking to 531 cause any damage to the Tungsten? Thanks for all of your input.

Hello there,
I haven't had too much experience with overclocking, but overclocking causes your processor to become faster and as far as I know, you should be really careful, otherwise, you could ruin your palm. In my case, I haven't had too much luck overclocking my palm tungsten E2, so, overclocking also depends on your palm model. Some models overclock a lot better than others and even the same models have differnet overclocking potentials.

Hope that helps

Concerning overclocking, if you go too far with the T|C, you'll be greeted with a white-with-color-streaks screen that can only be escaped from by either letting the battery drain or opening the unit and un-plugging the battery. (No, a stab in the back won't work.)

Here are the settings I use with warpSpeed:

MEM: 118
BUS: 3
CPU: 3

I could boost MEM speed to 133 and still run fine(resulting in 598 MHz), but there is no apparent benefit according to Speedy, LJP, and the FPS ports. The biggest amplifier of speed appears to be the CPU-memory bus, though if you lower the CPU clock too much, even that won't really help.

As far as correcting that bloody slowdown goes, I think it's a software implementation issue within the Palm OS. The CLIÉs and Treos don't have the problem from what I've heard, and I've found that enabling IR keyboard support in ZDoomZ and ZQuake actually doesn't have any slowdown upon pressing any of the keyboard's keys! Furthermore, when running T|C Linux, I didn't see any excessive CPU load upon pressing any of the keys. (I'll have to test that a bit more, though, as I don't know how to set up any Linux console emulators for ARM platforms. Maybe I ought to look through some Zaurus sites...)

Hey namelessplayer,
Just wondering, for warpspeed, what should you increase first from MEM, BUS and CPU to be safe? I have a palm tungsten E2 which is an NVFS device, so, I don't wanna brick it, but what's the best starting point in warpspeed to overclock?
One more thing, sometimes(this happened only a couple of times), when I open a program, the palm screen fades by itself . It's done this several times over the last ~7 month, so, what could this be ?

Thanks

[namelessplayer]

I only have experience with the Tungsten C and E, so I don't know all that much about NVFS or FrankenGarnet devices. (I do know somebody with a LifeDrive, but I doubt he'll let me mess with it-these are PERSONAL devices, after all!)

All I can suggest is to increase the settings gradually-and that goes for ANYTHING you overclock, whether it be your Palm or your PC.

T|E2 has a PXA270 at 200 MHz, right? It should be able to OC right up to 624 MHz since Palm underclocks devices to save battery life, but as with ANYTHING you overclock, I would suggest to bump things up gradually. Try bumping the bus clock up a notch first, and then working the memory and CPU clocks.

And as for the fading screen problem, I have no idea since as I've said, I haven't touched an E2. All I can suggest is to:

-Backup your programs and data
-Hard reset the thing
-Install a file manger like FileZ and delete any leftover databases and whatnot(going by Brighthand T|C advocate internetpilot's experiences with the T|X, a hard reset doesn't quite delete everything)
-Hard reset it again
-Restore just your PIM data, and then your apps one by one to ensure you're not putting the cause of the problem back on again

ok, thanks a lot
I actually never knew a palm tungsten E2 can be overclocked to 624mhz. It has a 200 MHz Intel PXA260/PXA255 processor, so, I don't know how high that go. How much difference is there between 260 and 270?

Thanks again for the info ;D

[namelessplayer]

I'm guessing on the 624 MHz part since that's the highest official clock for the Intel XScale PXA270 that most modern Palms, T|E2 included, use...wait, it's not a PXA270, but a PXA260 or PXA255? I could have sworn that it used a PXA270...

If it's the PXA255, the highest official clock is 400 MHz. My T|C with the same CPU can run at 531 MHz fine, though bumping up memory clock does nothing beyond that point and increasing the CPU clock will hang the unit, requiring a stab in the back.

Between the PXA255 and PXA270(don't know anything about the 260, but it might be a PXA255 plus Intel StrataFlash), the 270 has the additions of WMMX, Wireless SpeedStep(don't ask me why they have to insert the "wireless" bit), a hardware button matrix controller(PXA255 handles buttons in software, which is probably why the T|C gets slowdown upon button presses in Palm OS), and other myriad architecture improvements that should increase performance per clock while decreasing power requirements.

[needhelp]

ok, thanks. I checked the processor in TCPMP and it says "ARM Intel PXA25x/26x ~206Mhz", so, I have no clue which one it is(The PXA255 or PXA260). Just wondering, how can you tell when you successfully overclocked your T|C?

Thanks

[namelessplayer]

I can tell that the OC works because:

-Speedy shows a performance increase
-LJP and MetaView's FPS ports run noticeably better

However, I just noticed that in this other thread, Lightspeed apparently hasn't worked out for you. Tried warpSpeed(my app of choice)or PXA Clocker yet?

[needhelp]

well, I tried pxa clocker and no luck. I tried warpspeed sometime back and I noticed no change either, but that was way way back, so, I could have easily put it to 400 or so and it wouldn't do it. I might try warpspeed again.
For speedy, do u run it? Then overclock a program and run that program? Then after running the program, check speedy again?

Thanks a lot for the advice

[_Em]

An easy way to check if the clockers are working: set the clock speed to ~60MHz, and see if things slow down. Remember that the apps have to be stored in memory, and set to load on soft reset. Also, if you've ever installed WarpSpeed, you might find that your trial has expired now. PXA Clocker should do just fine for you however.

[needhelp]

ok. However, how should I work pxa clocker? I mean what should I change first and by how much?

Thanks
