Example Description

This example describes how to convert ADC regular group channels continuously using TIM1 external trigger and injected group channels using the auto-injected feature.

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 convert on each TIM1 capture compare event ADC channel14(PC4).
    • Each time an end of regular conversion occurs the DMA transfers the converted data from ADC1 DR register to the ADC_RegularConvertedValueTab table.
    • Enabling the auto-injected feature, allows to convert automatically the injected channel ADC channel11(PC1) after the end of the regular channel14.
How to use it ?

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

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