hi, i was wondering how to connect an adc and a dac to a 8025 (DS89C420). do i have to use the two UARTs or it's better to use the "raw" i/o pins? what i'm trying to do is a sort of audio filter: the signal is converted in digital, read by the 8052 (where the fx are applied), and sent to the dac. moreover i'm using BB's PCM1802 as the ADC and PCM1744 as the DAC. the problem is these are all stereo adcs and dacs. do anyone knows about audio-oriented mono adcs and dacs? thank you for your help, CAFxX.
