IrDA driver and SD card file system on MM/JE Flexis families

This application note discusses a physical layer driver used to establish IrDA communication on Freescale devices in the MM/JE Flexis families, using the Carrier Modulator Timer (CMT) as transmitter and a Timer/Pulse-Width Modulator (TPM) as receptor.

It also explains a driver to handle a Secure Digital (SD) card through a serial peripheral interface (SPI) module, plus a file system allowing the microcontroller to open, edit, save and close files stored in the SD card. Both drivers are available for download in a zip file associated with this application note.
