Using the PSP for LCDsmartie

EVIL ERNIE · Post by **EVIL ERNIE** » September 22nd, 2008, 5:09 pm

I had a thought the other night while wiring up a new 2x16 serial LCD.

With all the Sony PSP programmers out there how hard would it be to write a homebrew program to take the info from LCDsmartie and display it on the PSP screen while hooked up through USB.

I am not a programmer so I have no idea.

I have also posted this on some PSP programming forums but received little or no answers.

Thanks

PSP -> PC is a mass stoge drive

If PSP is run in mass stoge mode, It can't running any program

The only way ,is you can wirte a program for cracked psp firmware use plugin mode...

This is not easy...

If the PSP can be used only as USB storage, but can have concurrent access to its memory alongside the PC then you can make a text exporting plugin for Smartie and save the file to the PSP shared location.

I strongly advise against it if the memory is flash (memory stick) as that wears out quickly. If you could share a "virtual drive" in the PSP RAM that would be great!

The most easy way is wireless, I think that the PSP has wifi onboard, so making a listening TCP service should be easily done for it and make a simple protocol to put on screen the received TCP packets!

If you get the PSP program done then I'll provide you with the Smartie plugin! Just write here when you are set so we can discuss the communication protocol.

Like I said before I am no programmer so I was just putting the idea out there to see if it was even remotely possible to make.

Why could it not be a homebrew app that monitored the usb for signals from the program then display on screen.

There is a PSP plugin that allows the video signal to be sent via usb to a computer. The drivers set the PSP up as PSP type B (USBHOST) and allow the signal from the PSP to be seen on the PC screen. I just figured there would be a way to do this in reverse.

Thanks for the answers

Interesting facts!
I don't know anything about coding for the PSP either.
You can try to find somebody that can code the PSP part for you.
Surely there must be others that will love to use the PSP to display system stats. They just don't know about LCD Smartie yet!

Well I am still posting the idea on every PSP forum I can think of to see if I can get someone interested in working on this project.

With all the PSP's out there it could be a pretty big thing.

Thanks for the reply's

PSP LCD is not a shandow in memory address

It have a display card

All of display data must be use psp graph port

To be honest I don't think using a PSP in place of a standard LCD would be all that difficult.
The hardest part would be getting the PC to communicate with the PSP... I haven't written a program for the PSP in a little while now but Im pretty sure the easiest way would be to use the PSP's serial port. That way, providing you only want the PSP to emulate an mXn LCD, the you wouldn't need to make any new drivers for LCDSmartie either

I'd up for trying to make this happen if there's people interested in it. I'll
have a look around to see if I can find any useful info & a cheap PSP remote to hack up
