Digital data recorder altitude for radio controlled model aircraft

V tomto príspevku sa venujeme návrhu a vyhotoveniu digitálneho zaznamenávača výšky rádiom riadeného modelu lietadla. Zariadenie ukladá namerané dáta z modelu lietadla, každú jednu sekundu po dobu viac ako dvoch hodín. Zariadenie pracuje pomocou mikrokontroléra ATmega 168 PA. ATmega 168 je 8-bit AVR RISC-based mikrokontrolér. Ďalšími dôležitými časťami zariadenia sú tlakový barometrický senzor BMP085 a sériová pamäť EEPROM 24LC256. Zariadenie pracuje s citlivosťou 25cm. Analýza nameraných hodnôt je možná cez MS Excel pomocou prevodníka PLX-DAQ.This post is devoted to design and construct the digital data recorder of altitude for radio controlled model aircraft. The Device stores data of model aircraft, every one second for more than two hours. The device works by using microcontroller ATmega 168 PA. ATmega 168 is high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller. Microcontroller supports a throughput of 20 MIPS at 20 MHz and operates between 2.7-5.5 volts. Other important components are Barometric Pressure Sensor - BMP085 and 24LC256 Serial Electrically Erasable PROM. The device operates with sensitivity 25 cm. Analyzation of the measured data is possible via MS Excel, with using converter PLX-DAQ
