Wanted to confirm if the input/output voltage is 3.3V or 5V depending on the I/O structure of my pin . I scoped a PWM signal with the board connected to the PC and on the dedicated pin I see the signal in mV. I would like to send a higher voltage th...

I've wrote a code without using Hal to produce a signal on the scope but i'm not getting any signal on my pin.This is on a NUCLEO F401RE. Using TIMER3_CHANNEL1 and GPIOB for my Alternate function. #include <stdint.h>#include "stm32f4xx.h"#include "st...

All my inputs are assigned to the PWM , but by default only on rotates and if i switch one ore do another PWM it doesn't work . Don't understand why's that.Looked at both schematic and ii don't know why that's happening.

I've made changes and took on your advice , wasn't getting a signal still when I run it . I know when using CUBE/HAL you need to set the clock config tree, and as I'm writing manually I don't have anything set for it ,could that be the issue?

This is a reference of the datasheet. The reset values are 0's hence, I am trying to SET pin 18 and leave the rest to 0 as highlighted. Not sure what you meant by saying that's not what I want ? Any further explanation would be helpful . Thanks

Setting peripheral clock same as the APB1 bus clock following the data sheet which is 42MHZ .It's from bit 0 to 5 on I2C control register 2.To what bit do I set it to?

I have connected with wires my L298 H-bridge to my STM32F401 . By default once plugin to the computer the motor starts rotating(only connected on motor) . On my connector D5 which is PWM makes it rotate if i plug the wire to another PWM it does not .
