can it maybe used for debricking a psp ? if so we need to start a new topic in psp history i meen 2.0 -> 1.5 Fireware downgrader exits and now a 2.1 2.5 2.6 2.7 -> 1.5 downgrader exits also (by Dark Alex)( Check http://www.sonyxteam.com if u dont trust me :) ) so its now time for finding a way to debrick a psp :) Greets Ep0xZ

I would like to do that with a PIC!

My friend code it and I made the hardware but had some trouble with the serial communication. I am looking for a chip that conver 0v to 2,5V and 5V to 0V. I did it using diode and resitor but I am not 100% sure if it is software or hardware!

I think the best part that everyone missed is:

Of course there’s a serial interface: Universal -serial- bus.

#1: there is, it’s called psplink… it also works over usb and wifi, and is the one tool you really need for developing homebrew on psp.

#7: marcus is good at getting credit for other people’s work too….

#8: This has been around for quite a while, and now we are to a point where USB is far more useful for development than this serial port is.

I think #4 is joking – since Sony claim to have invented everything.

lemon (#4): ya, having serial ports makes the PSP wide open to all kinds of hardware interfacing projects. robotics, serial terminal, remote controlling, internet, gps, datalogging, etc etc. if they just weren’t so expensive :P

uhh, mom/dad person, **you** need to get out and actually read something. i said “old” as in apple dropping serial ports on their machines because they’re “old” — it’s called ‘sarcasm’. oh, and al gore invented the internet, too. serial is perhaps the most common, and longest-running, digital communications protocol in history, and was definitely not invented by sony 2 years ago. get out and open your eyes.

yay its up! hopefully people can start looking that this and start developing.

That’s neat… I’ve been wanting to check this out, but I was afraid I couldn’t reassemble my remote.

Marcus (the guy who decoded the protocol: http://mc.pp.se/psp/phones.xhtml ) is a great hacker. We worked together on the Sega VMU ( http://www.maushammer.com/vmu.html ) & he also did most of the reverse engineering of the dreamcast console:

What I want to know is what happens when you send one of the missing command codes – 0002 or 0040.

The ipod’s remote is very similar – it uses a serial line, too, with a similar protocol, but doesn’t have the fancy chip-on-board IC. http://www.maushammer.com/systems/ipod-remote/ipod-remote.html

wow, post #4 has so many errors I just won’t bother.

I thought this was just going to be another IR port hack, I wasn’t expecting there to be a serial port either. Are there any programs out there for the PSP that let you drive the pins on the serial port? I might have to add it to my list of consumer electronics turned into robot controllers.

#1 Sony did not invent the serial interface

#2 serial ports have been in computing since the 80′s (probably before you were born)

#3 loldude learn your stuff
