Zener Regulator
If you were able to modify the circuit for 220V/50Hz operations, please let me know. If you can, please send the modified circuit to darkore(at)gmail(dot)com.
photodiode schematic
Hi all,
The short story: I'm looking for an infrared photodiode amplifier schematic that is to be used in a universal remote control project.
The long story: please note that I'm NOT looking for an integrated module (SFH5110 and such), as I don't want to have the signal...
interfacing keyboard with microcontroller
This is strange. Is the keyboard connected to a microcontroller which I/O pins force the data and/or clock lines to logical 1, by any chance?
keyboard interfacing with 8051
The keyboard should perform a RESET on startup, and this should be visible by looking at the LEDs, they should blink briefly. Check your electrical connections. Also be aware that the KB may need well above 100mA to function properly, so check if your power source...
Re: Program in C/C++
The reason is quite subtle and is has to do with the way the compiler works. In C, after compiling the source file that has "main" in it, you get an object. But any information about the type of 'main' is gone in this object. That is, the linker (that must be called in...
No matter what GUI you use, do the data acquisition in a separate thread with a priority larger than normal (REALTIME_PRIORITY_CLASS would probably be a good choice). Do NOT sample the data in the same thread, you won't stand a chance. Even so, the chances to sample the signal at 1MHz directly...
fet programmer
I'm afraid you can't find it anywhere. I made it myself and I never bothered to write down the schematic. Furthermore, I disassembled the prototype board and I have no reference to the schematic whatsoever :( I remember that it should be pretty easy to build though. Just look at...
uip ftp server
Yes,me. I tested the 0.6 version. I had to fix a bug in the IP code, but after this everything worked like a charm. I guess that bug is already fixed in 0.9, so I highly recommend it. I implemented an Ethernet bootloader and a toy app with a CS8900 on an old eZ80 board. However...
