How do I use the printf function on STM32?

I am trying to figure out how to use the printf function to print to the serial port. My current setup is STM32CubeMX generated code and SystemWorkbench32 with the STM32F407 discovery board. I see in stdio.h that the printf prototype is defined…

Why not always use DMA in favor of interrupts with UART on STM32?

I spend last month a lot of time getting UART (for MIDI) to work with an STM (STM32F103C8T6) using interrupts, without very much success. However, this evening using DMA it worked quite fast. Since as far as I read DMA is faster and relieves the…

STM32 - How does analog configuration of MCU pins affect the power usage?

When I was creating a new project using the STM32CubeMX, I saw a check box stating that setting all free pins as anlog will decrease the power consumption. I couldn't figure out how it works. How can configuring the free pins as analog decrease the…

LED blinks even when I don't press the button

I have written a program in Keil that blinks a LED via External GPIO Interrupt. Here is how I have configured it in STM32CubeMX: At first, I enabled and configured RCC as you can see and configured PA0 for external interrupt and PB1 as output. For…

I2C busy flag strange behaviour

I've been using STMCUBE combined with Keil for some time now. For most part I like the HAL library and the documentation for STM32f1xx drivers is quite good. I'm doing a project where I am using STM32f103rb Nucleo card combined with an MPU6050…

Did I kill my STM?

I have (had?) an STM32F429ZI. I was working with the ADC on PC0 and due to a hardware malfunction, 12V ran through the pin when the maximum voltage an ADC pin supports is 3V. Since then, whenever I connect the STM to my computer via the USB in CN1,…

How to debug current consumption with STM32 Nucleo board?

I'm trying to configure an STM32L011-Nucleo developement board to consume about 600 uA of current or so. It uses an STM32L011K4. The datasheet states that this should be possible if I drive the MCU at 8 MHz and keep it in sleep mode for most of the…

Why does STM32 use a two-stage initialization process? What is the primary purpose of each stage?

I'm learning to use STM32 microcontrollers using CubeMX to generate a project. I've noticed that CubeMX generates two basic stages of initialization for nearly every peripheral: (A) Within the stm32fxxxx_hap_msp.c file, it defines a number of…
