Helloi want to exit from STOP mode using RTC has in the example of STM32Cube\Repository\STM32Cube_FW_L4_V1.12.0\Projects\NUCLEO-L476RG\Examples\PWRBut the STM32 exits immediatly after the WFI execution.It works well with the HAL_PWR_EnterSTANDBYMode ...

Why do GP14 and PB15 GPIOS not work for me?

All other GPIOS work but these two do not. They get the same voltage as the rest (0 and 3.2V). All pins Vdd and Vss I have them well except pin 97 VDD_USB that by mistake I have connected to GND.I have attached the project with which I have been test...

sprintf doesn't work well to show float (I already added -u _printf_float in linker options)

Hi all, I have a problem to show float numbers via sprintf, I'm working with STM32F334I did a program to print via serial the voltage read from ADC, in float format like %4.2f, the problem is that the first time the sprintf generate a valid string wi...

STM32F3: Example to use internal timer interrupt (TIM6/7)?

I'm working over STM32f334, i config cubeMx to use TIM6 o TIM7 to generate interrupt every 20ms, but interrupt is not fired.I'm finding a official examples to use HAL to config TIM as internal interupt.Any idea? any ink?ThanksJordi
