A Direct AVR Parallel Access, or DAPA cable, is an incredibly simple and cheap programming method. You can build one very quickly for a few bucks worth of parts, but the convenience comes with a ...

As for the parallel port, well, I still have one around,but if it proves to be too slow (the AT29C needs a byte loaded every 250µs or so, which should be ok), I can still plug a microcontroller ...

So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc ...

I have recently learned a little bit of Visual Basic. I came up with an idea just a few minutes ago about a circuit that i could build that plugs into the parallel port that would control the ...

Today’s microcontrollers consume less current than their predecessors, so you can easily tap the serial port’s power for an Atmel AVR programmer . The programmer uses only two chips: IC 1 , a Maxim ...

Computers and other electronic equipment containing memory ICs can be tested, serviced, repaired, programmed or re-programmed with the Model 866 Universal Device Programmer. It ...
