Expand description

@brief Set DAC output voltage. DAC output is 8-bit. Maximum (255) corresponds to VDD3P3_RTC.

@note Need to configure DAC pad before calling this function. DAC channel 0 is attached to GPIO25, DAC channel 1 is attached to GPIO26 @param channel DAC channel @param dac_value DAC output value

@return - ESP_OK success
