Basically, you can write a code for the host MCU that will receive index numbers in interrupt to generate appropriate DAC value using the given index.
Are you saying I have to read data from speakUP UART/USB out using a PIC18F UART ISR (say) and depending upon the voice index received I have to set the value of DAC through PIC18F?
If yes, that is not what I need.
It should be something like this...
In next version of speakUP it should have onboard memory to store voice commands (lot of commands) + a SD card circuit and a DAC output for matched voice command, i.e., the speakUP onboard STM MCU itself should have DAC and it should be assigned value like 1, 2, 3, 4....1023 based on voice command(s). Then this speakUP's DAC o/p will be interfaced to user projects MCU like PIC or AVRs ADC and depending upon the adc value devices are controlled.
if voice command matches with stored cmd 1 then STM's DAC is assigned 1 (10 bit DAC) then DAC and hence ADC value read by PIC/AVR is 0.0048875855327468V. Using if condition in PIC/AVR like...
if adcval >= 0.00487 && < 0.0097751710654936 then do A
if adcval >= 0.0097751710654936 && < 0.0146627565982404 then do B
....
This is just to increase the no. of commands handled. I read that speakUP supports only 200 commands. I know 200 commands are more than enough for a project but just an additional feature will be more useful.
