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 ...

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 ...

External EPROM burners are pretty handy gadgets to have around. They obviously can read and write EPROMS, but often times they will also handle a pile of PIC’s, some AVR’s, and other pr… ...

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 ...

At the heart of the Arduino platform is an AVR microcontroller, in usual way you need a special hardware programmer and suitable hex files to program the Atmel AVR chip. Fortunately, Arduino is a ...

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 ...
