Návrh modulárního zařízení pro bezdrátový přenos řídicích signálů.

Abstract

This diploma thesis deals with proposal two modular expandable devices for wireless transmission of control signals. The first device serving as a "transmitter" collects digital data at its inputs and sends them wirelessly to another device serving as a "receiver" that these data as the input image is transferred to its output. For wireless transmission are very high TinyOne modules for working on the unlicensed 868 MHz band. The data processing and communication provide two microcomputers PIC 16F874 from Microchip. These microcomputers are equipped on the receiver module and the transmitter module. To increase the number of inputs and outputs on each side is the expansion modules equipped 16-bit expanders PCF8575 from Philips. Communication between the main and expansion modules are solved by I2C bus.
