Example Description

This example describes how to trigger ADC conversion by external line event.

In this example, Main clock is configured at 24MHz.

The UART1 is configured as follow:

  • BaudRate: 115200
  • Word Length: 8

ADC is configured to start conversion on EXTI2 event:
On detection of a rising edge on PA.2 pin, the conversion of ADC
channel_0(PC6) is done and its converted value is printed in the UART1.
