(analog to digital) adc_read

[Rackie]

I have this code in mikroC, it reads the 1k potentiometer, but when i use 5k potentiometer, it won't read.

potentiometer_value = ADC_Read(2);// Get 10-bit results of AD conversion

Is there any code to Get Get 16-bit results of AD conversion?

If you are using inbuilt ADC module of the micro-controller and mostly it will have 10 bit ADC. If you need 16 bit resolution, you need a module which have the capability of 16 bits resolution. There are many ic's which can do this. one is MCP3421 which has 18 bits of resolution. Connect MCP3421 to your controller using i2c and display the values with 16 bits of resolution.

Best wishes

What result are you getting? Upload the diagram showing the connection of the potentiometer.

To get a 16-bit result, use an external 16-bit ADC.

You may use the "oversampling" method.
For example, take a look at:

Hope this helps.
