New Idea for Out function(out digital bits)

[Ngel]

Any one thought about a way to control something with the psp? Not wire less but with the usb port, Like to out a digital digit or any thing?
Well, i got a new Idea, There is a function that run mp3 file (LUA PLAYER) so i can connect to the headset connection a A2D (analog to digital) or a kind of amplifier that will translate the analog wave (sound) to 5\0v (binary) and because its a stereo headset there is two bit so i will connect a special shift register to build up an 8 bits digit :) , I know how to do it and i done it before but i will get my psp next mounth :\

So what do you think about my idea? cool?

Why not use the IrDA or serial ports ? The headset connector already have a serial port, which could be used for that.

I saw some guides for lua and i didnt saw any function to out just a binary code only files.
i can use the IrDA, but there are functions to use it? :\

I don't know the LUA scripting language. But you could take a look at the GPS interface for the PSP. It uses the serial port for reading data from the GPS. That might point you to something.

The SIO example in the Lua Player release sends and receives strings on the serial port.

I've added IrDA support to Lua Player, it will be available in the next release. Or you can use this example, if you like to use C:

i dont know c :\
But i will love to see the next release !
I am trying to build up an circuit to convert the srial port to parallel, I think it will be much easy than use the infrared :\
(i will start build it up when i will get my psp, very soon )
Hm... One question...
System.sioInit(2400)
what is the frequency that i will have to use for the shift register?
i saw http://francis.courtois.free.fr/jc1/ser ... ormat.html
and if i'm sending 1 byte (8 bits) and Baud rate of 2400 so the frequency (shift register clock input) will be 300Hz ?

If you dont know what i'm talking about so i will ask my teacher tomorrow.
