Cuando se habla de filtros tenemos dos grandes posibilidades, trabajar con filtros analógicos o con filtros digitales. En este reporte hablaremos del diseño de un filtro digital programable de orden 50 con efecto pasa bajas, pasa altas o pasa banda utilizando la metodología de diseño de ventaneo de respuesta al impulso para filtros FIR
This MPLAB® X IDE example demonstrates how to generate a 100Hz sine wave without CPU intervention by configuring the DAC and DMA Drivers within MCC Melody.
This digital piano, driven by a TM4C123 MCU, integrates a speaker, amplifier, and DAC. It features a music box with three melodies, controlled by two switches, and a digital piano using a 6-bit R/2R DAC with 4 push buttons as keys. The system is coded in C++ using OOP, with the Sound class as its core and Music & Piano classes defining modes.
Direct Digital Synthesis via an MCP4822 SPI DAC on a PIC32MX550F256L. Should also work on other PIC32MX chips with similar peripherals, e.g. PIC32MX250F256L.
