The great god, you directly in the dac output voice, external speakers will go off first, and then play the voice

Before the problem is that the DAC output state is high or low level, in DAC work, have a level of jump has the problem, can try every other dc,

Hissing sound, first.mute increases slowly

CodePudding user response:

Everyone a great god, and I now hardware circuit can't change, can eliminate the voice through the software, is there anyone solution

CodePudding user response:

You can keep an intermediate DAC output value, such as your DAC is eight, can output 128 at ordinary times, quite and ac signal 0 level,

CodePudding user response:

Try to take off before enabling the DAC output voltage, given a recent pick up before you can make the voltage

CodePudding user response:

SPK_CS=0;
DAC_SetChannel1Data (DAC_aLIGN_12b_R, 0);
SPK_CS=1;

Before the play set dac output 0, can avoid even the appearance of the horn hissing sound
