i use the digital to analog converter.
When i write the maximum value for the dac in the analogWriteResolution = 4095, my output is only 2.88 Volt.
When i write the min. value 0, i get 680mV.
So why i didnt get in the max. 3.3 Volt ? And why i didtn get in the min 0 Volt ?
So, what would be the voltage, when i use the half value 4095/2 ? I have the voltage measured 1,76 Volt, why not 1.44 Volt ?
Could someone explaine it please ?
How can i solve this problem or in other words:
What are the exact values for the proper voltages ?
