DAC's extremely possible
A few persons are interested with my use of a DAC so here's a quick explanation.
I could have used an inbuilt timer, PWM and filter network but I decided to experiment with a DAC and some additional buffer 2Mbit (256k * 8) FRAM memory.
Although out of scope of the Road Test guidelines, I am experimenting with WiFi audio communications using the CC3000 and Fraunchpad.
Without resorting to any CODEC, compression algorithms or additional ASICs I wanted to give my project a voice.
This will be accomplished by uploading raw PCM data via WiFi to the 256Kbyte buffer and replaying under MSP430 control.
The PCB should be completed shortly with testing commencing immediately after.
I could be making a talking scale that says "One at a time please!" or may be making something completely different.
