In this multiple-part guide series on LIN (Local Interconnect Network) bus for STM32F4, I will cover its fundamentals and implementation. Part one will introduce the LIN bus and focus on the initial serial setup for communication. In this guid...
READ MOREIn this guide, we shall see how to use micropython to read analog signal applied to analog pin of STM32F411 Nucleo-64. In this guide, we shall cover the following: 1. What is ADC: In electronics, an analog-to-digital...
READ MOREIn this guide, we shall see how configure a GPIO as input and read the GPIO pin state and toggle the LED with each press from the push button. In this guide, we shall cover the following: 1. Gathering the Information: From the user manual of...
READ MOREAfter we have learnt how to compile and flash the board with micropython, in this guide, we shall use micropython to control on the board LED. This guide shall cover the basic of GPIO control in output mode. In this guide, we shall cover the...
READ MOREIn this guide, we shall see how to compile the micropython core for STM32F411 Nucleo-64 and burn the compiled version to the board. In this guide, we shall cover the following: 1. Compiling the Micropython: Note: Here we are assume that your...
READ MOREIn this guide, we shall see what is rotary encoder and how to use timer of the STM32H5 to read the pulses using hardware which will relief the MCU from processing the pulses of the encoder. In this guide, we shall cover the following: 1. What is...
READ MOREThe ST7920-based 128×64 GLCD is a versatile graphical display commonly used in embedded systems for visualizing text and graphics. When interfaced with an STM32F4 using SPI, it enables efficient communication while minimizing pin usage. This...
READ MOREIn this guide, we shall use DMA to transmit data over SPI bus to relief the CPU and make it free to do something else. In this guide, we shall cover the following: 1. Why to Use DMA with SPI: Using DMA with SPI in STM32 is highly...
READ MOREIn the second part of building library for 1602 LCD, we shall intialize the LCD and start writing some data to the display. In this guide, we shall cover the following: 4. Creating Header and Source Files: After the project has been generated by...
READ MOREIn this guide, we shall cover how to transmit and receive data from a slave device connected to out STM32H5. The slave device is ADXL345 accelerometer. In this guide, we shall cover the following: 1. Configure the SPI for ADXL345: Open SPI_TX.ioc...
READ MOREThis guide is part one of a two-part series that explains how to interface a 1602 Liquid Crystal Display (LCD) module with the HD44780 driver to an STM32F4 microcontroller. In this part, we focus on the LCD features, hardware connections, and...
READ MOREThe SPI (Serial Peripheral Interface) on the STM32H5 microcontroller provides a fast and flexible means of serial communication, ideal for connecting peripherals such as sensors or memory devices. In this guide, we focus on configuring the SPI...
