how gpio toogle on STM32 NUCLEO L4R5ZI can be configured?

[jesal.patel]

hello team,

I am trying to get started with NUCLEO l4r5zi board.

The first program i am doing is to blink a LED on board (PB7) .

Problem is the program builds successfully and is loaded on the board . but the LED is not blinking.

Moreover the Console reads a breakpoint on MX_INIT_GPIO.

Please guide me with the procedure to perform this .

I also surfed for the similar post, where I got an thread which stated to change the clock from HSE to HSI / MSI . but It didn't work for me.

Hello,

Check the VDD_MCU, as LD2 (which is connected to PB7) cannot work with VDD_MCU= 1.8 V.

Kind Regards,

Imen

Hello Imen,

Thank you for guiding.

The device is powered by USB.

I could now succesfully perform the blink program.

Now the issue i am facing is with the ADC polling program. At the debug window it shows the target not found error.

Please guide me with ADC example. I want to get analog input of 0-3.3V from a potentiometer for generating an output pwm signal.

Kind Regards,

Jesal

Hi @jesal.patel​ ,

I recommend you the ADC example available in the STM32CubeL4 version 1.13.0:

STM32Cube_FW_L4_V1.13.0\Projects\NUCLEO-L4R5ZI\Examples\ADC\ADC_RegularConversion_Polling

This will help you to use the ADC in Polling mode.

You find more details on how to use the example in the readme.txt file.

Kind Regards,

Imen.
