The ATmega 1284P microcontroller outputs a composite video signal and handles inputs from a PS/2 keyboard. ... BASIC has amused several generations of emergent geeks. It still does… ...

A 4MHz Z80 that can run BASIC with 64K of RAM, all built on a breadboard with 4 ICs. ... The ATMega serves as a clock and reset generator. It also is the computer’s EPROM.

Next, write-compile-build and burn the associated code to ATmega 8 as before. If everything is OK, the LED at pin 28 starts blinking for 6 times when you push the pushbutton switch (S2) for a while.

It's the same basic design found in the Arduino prototyping platform: a microcontroller, designed to use its 32 pins to interface with external hardware like sensors, motors and LEDs.

ATmega has some advantages over ATtiny, but mainly in capacity, not so much in features. Conversely, they're likely much easier to switch between than PIC16F and PIC18F<BR>7.

As promised, in the upcoming part, I will try to explain all about the basic bitwise operators and thereafter disclose how to combine them to perform certain common useful operations. → Part 8: Basic ...
