Data on 24 bitad, some people say that online can achieve high 19 - even when they do, and I was only 12 bit, board don't know what reason did not reasonable design, please give directions!

CodePudding user response:

Used C8051F350, but generally see said is how much a chip data accuracy, and then estimates is how much it is set to a configuration register, how many is how many chips can achieve a precision,

CodePudding user response:

I wonder if this brand in the domestic and technical support?

refer to the original poster McUatmel response:

The original poster to set up register ADC0CN? If not, ADC0CN on electric reset after a value of 0 b00010000, ADC is bipolar mode, distinguished - Vref ~ + Vref voltage range, 24 bit resolution; But for voltage range 0 to Vref is 12 bit, set ADC0CN 0 b00000000 setting the ADC model of single polarity can achieve the requirements of the building Lord,

Upstairs, I am a positive and negative to completely, bipolar work mode, I don't know where to write the precision of the 12 bit is used?
