Probably many of AVR software developers that use AVRStudio4 environment would like to program chips directly from AVRStudio4 using AVRISP. Usually we use simplified version of AVRISP that work with PonyProg or AVRDUDE. But here is solution, that can solve this problem.
In sixca.com is populated simplified version of AVR ISP programmer that works with ATMEL [...]

This is simple development board for Atmel AT89 series of microcontrollers that uses ISP programmability I found in sixca.com. This is good start for learning with MCS-51 base projects.

This board supports Atmel microcontroller series like AT89S51, AT89S52, AT89S53, AT89S8252 with DIP40 pin packages. The board uses ISP programming method through parallel port adapter. It has [...]

One of frequently used signal characteristics are energy and power. In signal theory these therms require additional comments because they are a bit different from these what we are used to use in AC or DC systems.
What is power and energy? If wee connect R resistor to voltage U, then resistor will dissipate some power [...]

This programmer isn’t widely popular as usually is easier to use ISP programming method. But sometimes if you need to disable RESET pin and use it as regular pin instead or you want to disable or restore SPI fuses who control ISP programming method, then you will need High-Voltage parallel programmer of AVR microcontrollers.
One of [...]

Avrdude-gui is a simple graphical user interface(GUI) for avrdude which is a command line tool running on several OS to program the Atmel AVR Microcontrollers. AVRDUDE-GUI is included in WinAVR toollset and can be used separately to program AVR chips avoiding command line as it has to be done with plain AVRDUDE.

This program has [...]

The board is very neat and convenient to use. If you’re just starting to learn prototyping AVR microcontrollers this is just what you might need.

If you use DIP socket instead soldering AVR microcontroller directly, then you can interchange following AVR’s: ATMEGA16(L), ATMEGA163(L), ATMEGA32(L), ATMEGA332(L), AT90S8535(L) – well some of them are obsolete models. [...]

This is not new program, but I decided to add it here because I found it very handy in many cases while developing ASM programs.

This small program generates delay loops for ATMEL AVR controllers. It’s multilingual – forn now it supports English and German languages. [...]

Usually we are used to connect LCD displays to 5V systems. As LCD controllers usually require 5V power supply there must be some compliant circuitry used when interfacing to 3V systems like ARM LPC2000 microcontrollers and so on.
Here are few examples how this problem could be solved.
Solution number1:

Standard LCD microcontroller can work with lowered power [...]

Usually keyboard is connected by using matrix type of connection – rows and columns. For instance for 12 button keyboard wee need 3+4 digital inputs of microcontroller. There is a way to build keyboard and connect to microcontroller using only one wire. For this we will need only signal wire, power and ground and of [...]
