MSP Mojo

Using QF1D512 to add precision digital filtering capability to your MSP-430 designs.

 Product Brief

 Software

Audio Mojo

The Audio-Mojo is a development board for the QF1D512 SavFIReTM digital filter chip.It features analog audio inputs and outputs, an audio codec, two QF1D512s and a microcontroller to provide non-volatile storage of settings and automatic load and run at power up. This board allows the QF1D512 to be evaluated for numerous audio applications including equalizer and digital speaker crossovers. Two complete sttings are pre-programmed into the board to illustrate stereo equalizer and digital crossover functionality.
