DAC1/2

[gilad]

trying to use DAC1/2 by following simple code:
can't see any changes on output nor on esp32(25/26)
dac_output_enable(DAC_CHANNEL_1);
dac_output_enable(DAC_CHANNEL_2);
dac_output_voltage(DAC_CHANNEL_1,0);
dac_output_voltage(DAC_CHANNEL_2,0);

i see no changes no matter the values, how come ?

what is the meaning for Strapping is it needed any human interact to activate it?
