ok, now I have put fw 4.01. on my psp 1000, I tried the sio test app, set baud to 4800 and everything work, in the xmb or psp browser the chatpad don't work...before with fw 5.0 m33-6 in xmb / browser chatpad mismatch keys...now don't work at all... I tried to reflash the chatpad firmware with baud ...

but if i can change the baud in sio test app, and make it work, so I think the problem is in the firmware of psp...i think... I have fw 5.00 m33-6 without 1.50 subset, I have noticed that pikey and this project is made to work with fw 3.XX, so if I change fw to 3.XX maybe the chatpad work, maybe fro...

tnx for reply, and how to change baudrate? in sio test application if I play with d pad minimum baud is 9600, in xmb I don't know how to change baud if you can explain me how to, you make me very happy :) OK OK ok, I change baud rate in sio test application and work very very well ok and in the xmb ...

hi tnx for the reply, I have check and re-check plugin, firmware of the chatpad and physical connection, I also tried to push as you say people +a and people + s, and make test, but in both type the write mismatched with buttons I pushed...you said to check also the baud rate of serial connection, b...

Hi finally I bought a rs232 programmer so I flashed the firmware on the little chatpad, then I've tested with the sio tester app and when I push a button there is output on display. I've installed the pikey plugin and reboot the psp, insert the chatpad and go to browser, i tired to type something, b...

thanks for reply, i'm not using usb converter directly connected on LPT or COM port, today if i have enought time i'll go to buy items for this schematic...i'll connect on db9 http://pikdev.free.fr/IMAGES/jdm84-serial-prog.png regard on this scheme, the "C1" is 100nF, but where is the posi...

hi, I made a programmer with your schematic post before but pgmpic doesn't recognize the programmer and the pic.. so I've changed the scheme..it's a programmer for 16f84, post earlier, now the pc see the programmer, but when i insert the chatpad pgmpic doesn't see no programmer no pic, if i disconne...

thanks for fast reply, I saw that link, but to avoid errors in connection between chatpad --> programmer --> rs232 I look for a simpler scheme, without the socket, direct cable...as I see from datasheet of 16f883 the pins of chip have this numbers: 1 v+ 20(vdd) 2 mlcr 1 3 cspclk 27 4 cspdat 28 5 pgm...

hi all, i'm new to the forum, i'm very interested in this project, I bought the chatpad, and now is disassembled on my desk... right now to continue the mod i should flash the chip of the chatpad, but I haven't found any clear scheme of programmer for 16f883... in the archive that jean shares, there...
