ATmega1284

The high-performance Microchip 8-bit AVR RISC-based microcontroller combines 128KB ISP flash memory with read-while-write capabilities, 4KB EEPROM, 16KB SRAM, 32 general purpose I/O lines, 32 general purpose working registers, a real time counter, three flexible timer/counters with compare modes and PWM, two USARTs, a byte oriented 2-wire serial interface, an 8-channel 10-bit A/D converter with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, SPI serial port, a JTAG (IEEE 1149.1 compliant) test interface for on-chip debugging and programming, and six software selectable power saving modes. The device operates between 1.8-5.5 volts. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.

Recreating classic games with a bare MCU

“Some time ago, I hatched a plan to introduce my kids to a handful of classic computer games. This wasn’t a matter of misplaced nostalgia: I’m not overly sentimental and I’d rather play Horizon Zero Dawn than …

1024 Samples FFT Spectrum Analyzer Using an Atmega1284

“This relatively easy tutorial (considering the complexity of this subject matter) will show you how you can make a very simple 1024 samples spectrum analyser using an Arduino type board (1284 Narrow) and the serial plotter. Any kind of Arduino …

The Amethyst Colour Video System

“The Amethyst is a retro-styled “home computer” built around an Atmel ATmega1284 microcontroller. It features composite (NTSC) video output with both high-color and high-resolution modes, mono audio output, and a full-travel mechanical keyboard. It includes a full-featured implementation of the …

ATMega1284 Bottle Boat

“This device is a bottle boat that is powered by an ATMega1284 microcontroller, two DC motors, bluetooth control, a water level sensor, and an L293D motor driver. Another microcontroller may be used and will have many code differences. The body …

Tiny Lisp Computer 2

“My aim in designing the first Tiny Lisp Computer was to create the smallest practical self-contained computer, with its own display and keyboard, that you could use to program in Lisp. This second version extends the original Tiny Lisp Computer …
