Example Description

This example describes how to use the ADC1 and DMA to transfer continuously converted data from ADC1 to memory. The ADC1 is configured to convert continuously channel14. Each time an end of conversion occurs the DMA transfers, in circular mode, the converted data from ADC1 DR register to the ADCConvertedValue variable. The ADC1 clock is set to 12 MHz on Value line devices and to 14MHz on other devices.
