At89c2051 Programming Software

The 8051 (also known as MCS-51) is an MCU design from the 80's that remains popular today. Modern 8051-compatible microcontrollers are available from multiple vendors, in all shapes and sizes, and with a wide range of peripherals. In this instructable we will be looking at the AT89C2051 MCU from Atmel.

If you want to have odd and even headers or footers–for example, if you want the page number on the outside corner of every page–double-click in the header or footer, and then click the Different Odd & Even Pages check box in the Options group. Programma dlya pechati knig iz word a song.

Fully Static Operation: 0 Hz to 24 MHz. • Two-Level Program Memory Lock. 128 x 8-Bit Internal RAM. Glober font torrent. • 15 Programmable VO Lines. • Two 16-Bit Timer/Counters.

AT89C2051 is a small (2Kbyte Flash, 128byte RAM), cheap (~$1.40 per chip) microcontroller. Features: • 2.7-6V operation • 15 I/O lines • 2 timers (16 bit) • Internal and external interrupts • UART • On-chip analog comparator • Up to 2MIPS with a 24MHz clock.

Motivation Being young and stupid I bought a microcontroller without checking for programmer and programming software availability. Fortunately, the programming protocol is simple, and I was able to make my own programmer based on an Arduino.

Features • Flashes IntelHex files • Verifies uploads • Erases flash • Dumps flash from chip to a file • Verifies chip ID • Works on Linux • Probably usable on Windows • Requires only a small software modification to allow for AT89C4051 programming Guide A more detailed guide to using this programmer can be found in.
