Hello!
How do we choose the domain of the image enhancement?
Also, if someone provides two "identical" images, can we confirm that the domain it applies?
Hi,
For a differential sensor, the external reference capacitor is 50pF. One is a variable capacitor 50 + (0-5)pF.
What is the difference if I just use 1 variable capacitor?
I find that Arduino only needs first high 7 bits. I think it does not need to write last bit.
But I still do not know how to enter command mode and retrieve the value of register.

Anyone help?
Now I add 1 more.
Wire.beginTransmission(0x50);
But all are 255. I see that the IC will send something called slave ACK which is 1 bit.
Do I wait for that ACK before sending requestFrom?
Is my address of the device wrong?
I see that it is set 0101000 as default.
Then is it 0x50?
Hello!
I want to retrieve the value of C_Config.
My code:
Wire.begin();
Wire.beginTransmission(0x50);
Wire.write(0xA0); // Enter the command mode
Wire.endTransmission();
Wire.requestFrom(0x06, 3); // Retrieve the value of C_Config
byte a = Wire.read();
byte...
24-Bit Capacitance-to-Digital Converter
with Temperature Sensor
What is the meaning of with Temperature Sensor?
It is a 16-pin one.
How should I look the datasheet?
For this converters, do I need to program it?
I think there are many things I do not understand.
Resolution down to 4 aF (that is...
Yes!
The result should be in range of 0m - 10000m with 10cm resolution.
If the range of capacitance is 0 - 4pF, it should be 0.00004pF resolution.
Am I right?
I am trying to use this method to have smaller resolution as I can.

result is the altitude
sensor is changing...
To have 0.0001pF, we should have higher resolution of frequency.
Is there any method to get higher resolution of frequency?
Can I prolong the time for measure the occurences and later on, just divide the measurement by the time?
Hey Peter,
I have watched your doc.
I see that the circuit has a switch to measure 2 frequencies.
But for Kerry Wong one, I do not see any switch to measure 2 frequencies.
