Example Description

This example describes how to use the 3 ADCs in independent conversions.

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 continuously ADC channel14(PC4).
    • ADC2 is configured to convert continuously ADC channel13(PC3).
    • ADC3 is configured to convert continuously ADC channel12(PC2).
    • ADC1 and ADC3 are transferring continuously converted data using DMA while ADC2 converted data are stored using End of conversion interrupt.
    • The result of ADC1, ADC2 and ADC3 conversion is monitored through the three variables: ADC1ConvertedValue, ADC2ConvertedValue and ADC3ConvertedValue.
How to use it ?

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

  • Open ADC_3ADCs_DMA.uvprojx from this example folder by Keil MDK5
  • Rebuild all files and load your image into target memory
  • Run the example
