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.

ADC1 is configured to convert on each TIM1 capture compare event ADC channel14. 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 after the end of the regular channel14. An ADC interrupt is generated then by JEOC flag at the end of the injected channel conversion and in the interrupt routine the result is stored in the ADC_InjectedConvertedValueTab table. The procedure is repeated 32 times then the TIM1 peripheral is disabled and thus, no conversion will be done neither regular nor injected. TIM1 start conversion triggers can be visualized on oscilloscope on PA.08 and at the same time the toggle of pin PC.06 which indicates the automatic auto-injection conversion.

The ADC1 clock is set to 12 MHz on Value line devices and to 14MHz on other devices.
