Why Does ADC Reading Work Only One Time?

[AlexanderKibarov]

Hello,

I am using the STM32F413ZH model. In fact, there is no problem in the code I wrote below, everything works correctly, but if I call the HAL_ADC_START function outside the while and do not use the HAL_ADC_STOP command, this time it only makes one reading, what is the reason for this? In this case, he has to read continuously, doesn't he?

Thank You.

Hello @AlexanderKibarov,

You can find in the reference manual of the STM32F413ZH microcontroller [Link: here]:  information about ADC conversion modes (Single Conversion and Continuous Conversion).

Additionally, the two examples available in STM32CubeF4, namely ADC_RegularConversion_DMA and ADC_RegularConversion_Interrupt, can guide you for the correct implementation.

I hope my answer has helped you. When your question is answered, please select this topic as solution that answered you, it will help others find that answer faster.

Thanks for your contribution.
