Well, an audio in connection usually expects a variable voltage ranging from -1v to +1v, while a microphone one expects resistence or capacitance variation. Since (for Ohm's law) V=RI, it is usually safe to connect a line-out to a mic-in through the use of a serie resistor. However, if you want thin...

My chatpad's replacement firmware totally screws things on xbox side, i.e. you won't be able to use chatpad the common way again. So, open keyboard has nothing to do with HID; despite of this, it is trivial to make it work on a PC because it uses true asynchronous serial protocol (e.g. rs232): the o...

Well, maybe because its not a completely valid argument :-P It is. This month it is 21 years since my first listing (written on an Olivetti PC128s - a BBC Acorn italian replica). Since then i read many books, but the most i've learned, it's taken from experience. Today, children want all and immedi...

Not enough to make a difference at serial speeds. Exactly, in paricular when you use the usart. To return up to pic power voltage, i must admit that Microchip's products are different from stock to stock and there's some exemplar that i wasn't able to program with my simple programmer, probably due...

The PIC's UART will anyway not function with the PSP's 2.5v port. The IO ports need 5v to trigger (When UART is activated on the 16f87x IO ports C6 and C7 become Tx and Rx). You'll need to pull up the voltage anyway. If it doesn't work with the UART pins for some reason, there are plenty of softwar...

Well...a lot of time passed since the last time i flashed my keyboard, but i do remember that the chatpad used to flash lights at the connection and during programming...i'm sure you're on the right way. Just a little advice: try to flash the keyboard (without verify), then read back content and com...

User mode functions don't use syscalls.... Although he could just patch the functions to syscall into his kernel module, instead of hooking it with another user module. Honestly: i never thought this way, that's interesting.... but there could be severe problems in the common case where one has to ...

Syscalls are a way to call kernel stuff from user world. So -if i understood it well- there is no syscall table regarding user functions and hence you cannot patch a user function via syscall table because you won't find an entry for your user function. You must find the function address and substit...

I cannot remember how man times i repeated this (specifically on THAT italian site's board)... No one needs to use a max level shifter to enstabilish communication between the PSP and a microcontroller. New Microchip's microampere technology allow us to power chip directly from SIO (the fact that my...

There's only a word to describe your attitude: laziness. If you bothered to search, not only you would have found that SIO equals to Serial Input Output, but you would have found dozens of projects involving SIO for debug or to attach keyboards, to connect with external devices such as barcode reade...
