need to wait for GPIO configure?

GPIO_Init(GPIOD, R4_GPIO_PINS, GPIO_Mode_In_FL_No_IT); GPIO_Init(GPIOD, R6_GPIO_PINS, GPIO_Mode_In_FL_No_IT); delay_ms(1); DOes gpio configure need to wait for completion?

Does anyone have a problem writing to Eeprom? When I try to write say a '0x80, a '0x3f' is reported as written So I stored my data as 4 bit nybbles, , which works (I'm using the discovery Board.) Russ

I have an smd diode with the ST logo on it. marking GBR6GP336. does anyone know the rating and description of it.

What is the process of porting over an example project from an stm32f4 to an stm32h7 board to use an x-nucelo gnss1a1 module?

I'd like to use the x-nucelo gnss1a1 module with the stm32h743zi2 nucleo board. Am I correct in thinking that there is a way to convert an example project that the x-cube gnss provides for the stm32f401re to be usable on the stm32h743zi2?   If so, I ...

Input Capture using timers.

HiI'm working on a BLDC Motor control project using STM8S Discovery Board (STM8S 105C6T6 MCU). I need to read the hall sensor inputs from my motor onto the three channels of TIM 2. So I thought of getting acquainted with the mechanism of input captur...

hi all i am new to stm8s ,i am trying to learn about timers in stm8s,i have one doubt to how to calcualte prescalar value.could somebody help me to calculate the prescalar value??

What is the sampling rate in adc??

I have some confusion about sampling rate in adc,in data sheet it conversion time takes 14 clock cycles, then i am using internal oscillator 16mhz and prescalar selection is 8 and i get conversation time is 3.5micro seconds,i want know about exactly ...
