Hello there,I am new to STM32 MCUs and been experimenting with different examples. I have below questions regarding WWDG.1. If you look commented section at line# 101 below. I understand the role of counter and window value but wondering where values...

Hello there,I have created my own project following the preconfigured project "ADC_RegularConversion_Interrupt". In my project I want to get the internal temperature sensor value and want to display it on the terminal thus using the UART example in t...

Hello there,I have created my own example to print the data on HyperTerminal (putty) following the already given example "UART_Printf" but mine is only printing the first char of the data and then stuck forever. Here is the clock config code and uar...

Hello @Sarra.S thanks for your quick response. regarding the 64 (window value) in the example window value is 127 (not 64) but the comment still says that the refresh time should be between 1 ms to 11 ms./* Refresh WWDG: update counter value to 127, ...

Actually, I got it working.Since I am still getting the gist of my new stm32f767, I did not have an adc interrupt callback set up in "stm32f7xx_it.c" file, thats why it was not getting any value from HAL_ADC_GetValue(). Thanks,

all what it does in this function to fetch the value from data registerreturn hadc->Instance->DR;thanks,

I have found the issue. Issue was with adc initialization, I guess some kind of priority, I need to look into this, but if I comment out the adc() and adc_channel() init function uart works. what could have caused it? is it systick interrupt priority...
