lpadc_polling#
Overview#
The lpadc_polling example shows the simplest way to use LPADC driver.
In this example, user should indicate a channel to provide a voltage signal (can be controlled by user) as the LPADC’s sample input. When running the project, typing any key into debug console would trigger the conversion. The execution would check the FIFO valid flag in loop until the flag is asserted, which means the conversion is completed. Then read the conversion result value and print it to debug console.
Note, the default setting of initialization for the ADC converter is just an available configuration. User can change the configuration structure’s setting in application to fit the special requirement.
