Can VPython be used with this?
http://www.vpython.org/

I think what a want it's not an Oscilloscope but a logic analyzer.

I'm only interested on binary voltage levels.

Is there a way to know if a pin on USB or Serial Port is high or low?

what other method of input could be used?

My next question will be a bit off topic but I hope it's not a big problem.

I found an old sound card and I wonder if I could avoid the DC measuring problem by removing and bypassing the capacitors right next to the line in and mic plug.

Any opinions?

I found this page that could be useful.

It explains the problems of using a sound card to measure DC signals. I haven't finished reading it but it looks like a valuable resource.

Thanks for the reply. Sorry, but i'm not very experienced with hardware. You will run into a problem trying to measure DC voltages, though, because there is usually a capacitor in the input before the ADC. As I said before, the main use i want to give this is to measure signals from microlcontrolers...

What circuit do I need to build to connect 5v TTL signals to the audio input of my PSP and not ruin it?

I'm not sure about USB, hardwarewise it gets much more complicated. My aim is to analyze the signals sent by a keyboard, pulses sent to a servo motor to control it or maybe signals sent on serial communication. This signals operate at frequencies lower than 44kz so I don't think this would be a prob...

I would like to use my PSP as an oscilloscope by connecting the input voltage to the analog audio input. The main use of this would be to make measurements on micro controller circuits with TTL voltage levels (6V-0V). Does somebody know what is the range of voltages supported by the audio input? Has...

The structure of your program is not right. You shouldn't define functions inside the main function. Also there's another thing. int sceUmdCheckMedium(void) { if (0) { //Trying to say 'if it returns 0' printf("No UMD inserted\n"&...

How can I read buffer in chunk?

When I try to do it, the string sent by the server is split as I explained on my first post.

What alternatives do I have other than using 'read' ?

I'm trying to create a client program that connects to a server on my computer. When I try to receive on the PSP a string sent by the server I only receive one character at first and then the rest of the string. This is the code I use: while(1) { bzero(&buffer, s...
