To access the ADC (Analog-to-Digital Converter) using MicroPython on a Raspberry Pi Pico, you can follow these steps:
- Import the necessary modules: Begin by importing the required modules for using the ADC in MicroPython. In this case, you'll need the machine module.
pythonCopy code
import machine
- Create an ADC object: Next, create an instance of the ADC object using the desired pin number.
pythonCopy code
adc = machine.ADC(26) In the example above, pin 26 is used as an example. You can replace it with the specific pin number to which your analog sensor is connected.
- Read the ADC value: To read the analog value from the ADC, you can use the read_u16() method.
pythonCopy code
adc_value = adc.read_u16() The read_u16() method returns the raw analog value as a 16-bit unsigned integer.
You can then use the adc_value variable to perform further calculations or use it as needed in your code.
It's important to note that the specific pin number and configuration may vary depending on your setup and the ADC pin you are using on the Raspberry Pi Pico. Refer to the documentation or specifications of your specific ADC module for the correct pin assignment and any additional configuration required.
Additionally, make sure you have the appropriate MicroPython firmware installed on your Raspberry Pi Pico, as it should include the necessary ADC support.
