PIC24FV16KM202 CLASS D AMPLIFIER

Class D amplifiers have become a popular audio amplifier topology due to their high efficiency and subsequent low cost. The high current output stage is implemented using binary switches, resulting in minimal heat generation and power loss. This allows for the power supply, heat sink and overall physical size of the amplifier to be minimized.…

SPI MMC to PIC Microcontroller ‘C’ code

For applications where more storage is required I would definately reccomend MultiMediaCards (some times called SanDisk (SD) flash). The built in SPI interface only requires four data lines and they are available in sizes of up to 256MByte (at the moment). There are a few little quirks in making the cards work with a PIC…
