In 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...
READ MOREIn this guide on RTC (Real-Time Clock), we shall explore the features of the RTC on STM32H5, its functional block diagram, and how to develop a driver using STM32CubeMX. In this guide, we shall cover the following: • What is RTC. • STM32CubeIDE...
READ MOREIn the second part of PCA9685 PWM module guide, we shall create the library that allow us to set the frequency and control the duty cycle of each individual channel. In this guide, we shall cover the following: 6. Creating the Header and Source...
READ MOREIn this guide, we shall see how to build a library to PCF9685. In this guide, we shall cover the following: 1. Introduction: The PCA9685 is a versatile 16-channel, 12-bit PWM controller widely used in applications requiring precise control of...
