Part Number: MSP430FR2355
Hello,
customer needs a compact solution for signalling tones, speech and sounds on a small loudspeaker and also measuring enviroments noise with a microphone. I thought to use MSP430FR2355 for this tasks. I thought of following way:
Measuring sound:
Microphone -> OA -> 12bit-ADC -> CPU
Generating sound:
Flash -> CPU/DMA -> 12bit DAC -> OA -> loudspeaker
Can this work? Is there any reference design?
