In 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...

In this new guide series, we shall start developing peripheral for ARM Cortex M7 based MCU with STM32F7 specially STM32F767Zi Nucelo-144. In this guide, we will cover the following: Getting the documents Developing bare metal GPIO output Demo 1...
READ MOREIn the previous guide (here), we saw how to use I2C to scan the bus for the slave devices address. In this guide, we shall see how to read a single byte using I. In this guide, we shall use DS3231. In this guide, we shall cover the following...
READ MOREIn this guide,, we will learn to interface a stepper motor with STM32F411RE Nucleo-64. There are many options available for stepper motors. But in this tutorial, we will use an inexpensive 28BYJ-48 stepper motor for interfacing with...
READ MOREIn the pervious guide, we took a look at how to send data over SPI (from here). In this guide, we shall use SPI to drive a lcd and display some variables on it. In this guide, we will need the following topics: SPI configuration : here Encoder...
READ MOREIn the previous guide(here), we looked at the operation principle of how ultrasonic works and we used very crude code to measure the distance. In this guide, we shall use external GPIO interrupt and timer 2 of the STM32F4 to measure the distance...
