In this guide, we shall take a look at the DMA which called Direct Memory Access of STM32F7 and how to use it in memory to memory to transfer 4-bytes from 1 memory location to another using DMA. In this guide, we will cover the following: What is...
READ MOREIn the previous guide (here), we took a look at how to configure the timer in PWM and we were able to update the duty cycle of the PWM to fade two LEDs using polling mode. In this guide, we shall look how to configure timer to update the duty...
READ MOREIn the previous guide (here), we discussed how to use the timer to generate accurate delay. In this guide, we shall look at another application for timer which is to generate PWM signal on two channels and fading two leds. In this guide, we will...
READ MOREIn this guide, we shall interface Nokia 5110 graphic LCD with STM32. In this guide, we will cover the following : Nokia 5110 graphic LCD LCD connection with STM32 Code Demo 1.1 Nokia 5110 Graphic LCD: Remember the days when cell phones were still...
READ MOREIn the previous guide (here), we took a look how to configure the PD8 to work as USART3 TX. In this guide, we shall use PD9 to receive characters over UART and echo back the received characters. In this guide, we shall cover the following...
READ MOREIn the pervious guide (here), we took a look how to interface Liquid Crystal Display (LCD) in 4-bit mode which requires 4-line of data, RS line and Enable line, in total 6 lines of the mcu has to be reserved for the LCD. In this guide, we shall...
READ MOREIn this article, we shall look at the dth11 temperature and humidity sensor and how does it work and interface it with STM32F4 Nucleo-64 board. In this guide, we shall cover the following: DHT11 Connection Code Demo 1. DHT11: The DHT11...
READ MOREIn this guide, we shall discuss how to use the UART module on STM32F7xx specifically, STM32F767ZI Nucleo. In this guide we will cover the following: What is UART How to configure the UART on STM32F767Zi Nucleo Code Demo 1. What is UART To...
READ MOREEver heard of MPU-9250? It is a multi-chip module (MCM) which consists of 2 dies, and houses the 3-Axis gyroscope and the 3-Axis accelerometer! Still unsure about how it works? Read on to find out! Hope that this article will help you understand...
READ MOREIn this guide, we shall investigate how to use timer to generate precise delay in down to microseconds ( will use 1 second delay here for demonstrations purposes only). In this guide, we will cover the following: What is the timer and how it...
READ MOREIn the previous guides, we took a look how to scan the i2c bus for peripherals (here), read single byte (here), write single byte (here), read multiple-bytes (here) and multiple-bytes(here). In this guide, we shall use DMA to transfer the data...
READ MOREThis tutorial teaches you how to interface an OLED display with STM32F411. In this article, we will show how to use SSD1306 0.96 inch I2C OLED with STM32F411-Nucleo64. This modern organic light emitting diode based display can be used...
