Example Description

This example describes how to use the ADC1 and DMA to transfer continuously converted data from ADC1 to memory.

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
    • The ADC1 is configured to convert continuously channel14(PC4).
    • Each time an end of conversion occurs the DMA transfers, in circular mode, the converted data from ADC1 DR register to the ADCConvertedValue variable
How to use it ?

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

  • Open ADC_ADC1_DMA.uvprojx from this example folder by Keil MDK5
  • Rebuild all files and load your image into target memory
  • Run the example
