Example Description

This example describes how to trigger ADC regular and injected groups channels conversion using two external line events.

In this example, Main clock is from PLL clock and it is configured at 96MHz. The PLL clock is based on 8MHz HSE. APB1 clock is the 2 frequency division of the Main clock, APB2 clock is from Main clock.

Hardware and Software environment
  • Hardware environment
    • HSE crystal is 8MHz
    • ADC1 is configured to start regular group channel conversion on EXTI11 event. On detection of the first falling edge on PC.11 pin ,the conversion of the regular channel (ADC channel_1) is done and its converted value is printed in the ADC1 EOC interruption.
    • ADC2 is configured to start injected group channel conversion on EXTI15 event. On detection of the first falling edge on PA.15 pin ,the conversion of the injected channel (ADC channel_10/channel_11) is done and its converted value is printed in the ADC2 JEOC interruption.
How to use it ?

In order to make the program work, you must do the following :

  • Open ADC_ExtLinesTrigger.uvprojx from this example folder by Keil MDK5
  • Rebuild all files and load your image into target memory
  • Run the example
