Processor PIC18F46K22 Applied as DTMF Generator
Original language description
The article describes an application of microcontroller PIC18F46K22 for generating DTMF(Dual Tone Multi-Frequemcy) signal. Used microcontroller is optimal for this application - it has timers with compare facilities, sufficient number of PWMs, powerfullinstruction set(extended - in comparison to classic PIC16xxx microcontrollers), etc. Problematics of article relates to more branches - electronics, filters, signal generators, microcontrollers, telecommunications, programming. An important purpose was to create an experimental platform based on powerfull microcontroller enabling implementation additional functions. There are together three different solutions of DTMF generating are described in article, they are compared as to the demands on external hardware and machine time of microcontroller. The first solution is based on sinus table, truncated onto 32 values. This solution uses 8-bit PORTD for value intended to external D/A converter. The second one solution exploits compare facil
