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 ...

The data are latched using the strobe signal of the parallel port. The lines with the host software are controlled by the Init signal of the parallel port. The HC273 device is used to control the CS ...

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 ...

HVPP: High-Voltage Parallel Programmer HVSP: High-Voltage Serial Programmer ISP: In-System Programmer (SPI) Based on AVR-Doper firmware running on ATMEGA32 in DIP-40 socket. AVRDUDE compatible, USB ...

The circuit is extremely simple. IC1 provides buffering for the signals that travel from the parallel port to the microcontroller and vice versa. This is essentially everything that can be said about ...

Programmer for AVR and PIC MC. Is based on AVR-Doper programmer. supports serial low-voltage, serial and parallel high-voltage modes for AVR, and high-voltage serial for PIC. Аlso has a serial port ...

In the old days it was very simple to use the parallel port of a standard PC and program just about any type of AVR microcontroller with it. When you want to do that now, you're first obliged ...

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 ...

Needhams Electronics' EMP-21 universal device programmer supports over 6600 devices and employs both USB and parallel ports for ... Family Module socket, parallel and USB port, and power connector.
