In this guide, we shall see how to use alphanumeric display. In this guide, we shall cover the following: Liquid Crystal display Initializing sequence Parts and connection Code Demo 1. Liquid Crystal Display Character display LCD ares used in so...
READ MOREIn the previous guide (here), we took a look how to control 28BYJ-48 stepper Motor. In this guide, we shall see how control NEMA17 stepper motor which is the most used stepper motor in 3D printers, CNC, robots etc. In this guide, we will cover...
READ MOREIn the pervious guide (here), we took a look how to configure the timer in encoder mode to read the pulses generated by the encoder. In this guide we cover the following: What is output compare mode Required parts Code Demo 1. What is output...
READ MOREIn the previous guide (here), we took a look how to configure the ADC in STM32F7 for single channel single conversion. In this guide, we shall configure the ADC in continuous mode conversion. In this guide, we will cover the following: Difference...
READ MOREIn the pervious guide, we took a look how to read multiple bytes using I2C (here). In this guide, we shall cover how to use I2C to write multiple bytes to I2C slave which in our case is DS3231. (for connect diagram from here and I2C initialize...
READ MOREIn the previous guide, we took a look at the STM32F7 blinking LED (here) and how to change the core frequency to push it to max 216MHz (here). In this guide, we shall use the ADC module to read the voltage applied to pin PA3 of the MCU. In this...
READ MOREIn pervious multiple guides, we took look at ADC with DMA (here), USART with DMA (here) and SPI-TX with DMA (here). In this guide, we shall use DMA to transfer data from one location to another using DMA. In this guide, we will cover the...
READ MOREIn the pervious guid (here), we took a look how to write/read single byte using I2C and the slave device is DS3231 In this guide, we shall see how to read multiple byte of DS3231 which they are seconds, minutes and hours and display them on the...
READ MOREIn the pervious guide (here), we took a look at how to control stepper motor. This guide is about DC motor interfacing with STM32F411 Nucleo-64. We will learn to control the speed of a DC motor using a pulse width modulation module (PWM) of...
READ MOREIn this guide, we shall use registers to change the core frequency from default 16MHz to 216MHz (maximum for F767ZIT). We shall use CubeMX to determine the values required to reach the 216MHz operation. 1. Getting required settings from CubeMX We...
READ MOREIn the pervious guide (from here), we took a look at DS3231 hardware and we read the second register and display the seconds on the terminal through UART. In this guide, we shall see how to write a single byte to a specific register. In this...
