Hi, I am trying to use NUCLEO-H743ZI ADC1, I am following the procedure that is recommended in the reference manual, getting out of deep power down, turning on and waiting for voltage regulator to stablize and then confirming these two things are happening. After this when I set ADEN bit of ADC1->CR register and polling for the ADRDY of  ADC1_ISR register, it is not getting set, means adc is not getting ready. I haven't changed any clock or power setting those are running in post reset default state. I am attaching my whole program with the library I am using, pease help me with this.

Thank You

Hi

‌,

The following ADC examples are available in

https://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-mcu-packages/stm32cubeh7.html

package underSTM32Cube_FW_H7_V1.2.0\Projects\STM32H743ZI-Nucleo\Examples\ADC:

Select one of them and try it. If the initially described issue is still there, please update us.

Otherwise, check the differences between your settings and the ones in the selected example to know what is wrong in your case.
