In this guide, we shall see how to interface MPU6050 with STM32F4xx. In this guide, we shall cover the following: What is MPU6050. Connection. Developing the driver. Code. Results. 1. What is MPU6050: The MPU-6050™ parts are the world’s...
READ MOREIn the previous guide (here), we took a look how to configure the timer to generate PWM signal and update the duty cycle in software. In this guide, we shall configure the time with PWM to update the duty cycle using DMA. In this guide, we shall...
READ MOREIn the previous guide (here), we tool a look for SPI in duplex mode using polling mode. In this guide, we shall see how to do SPI Full duplex using DMA. In this guide, we shall cover the following: Enable RXDMA for SPI. Configure DMA. SPI RX with...
READ MOREIn the previous guide (here), we took a look at keypad structure and how to initialize the keypad pins. In this guide, we shall develop the algorithm to read from keypad. In this guide, we shall cover the following: Read keypad function. Code...
READ MOREIn the past guides related to SPI, we worked only with single slave device. In this guide, we shall cover dealing with multiple slave devices. The slave devices in this case are: MPU9250. SSD1306 SPI OLED Monochrom display. In this guide, we...
READ MOREIn the previous guide (here), we saw how to transfer data over SPI using DMA. In this guide, we shall see how to receive data from SPI bus. In this guide, we shall cover the following: SPI Receive function. MPU9250 connection. Code. Results. 1...
READ MOREIn the previous guide (here), we saw how to transmit data over SPI using polling mode. In this guide, we shall use DMA to transmit data over SPI without CPU intervention. In this guide, we shall cover the following: Configure SPI in DMA TX mode...
READ MORESince most STM32Fxxx doesn’t feature internal EEPROM. Hence, this guide we shall use the internal flash to emulate EEPROM. In this guide, we shall cover the following: What is EEPROM. Develop the driver. Code. Results. 1. What is EEPROM...
READ MOREIn the previous guide (here), we took a look how to read from the internal flash of STM32F411. In this guide, we shall see how to write to the internal flash storage of STM32F411. In this guide, we shall cover the following: Steps required to...
READ MOREIn this guide, we shall see how to read data from the internal flash storage of STM32Fxxx (tested on STM32F1 and F4). In this guide, we shall cover the following: Internal Flash Storage of STM32F411. Develop the driver. Code. Results. 1. Internal...
READ MOREIn the previous guide (here), we took a look at ACS712 current sensor and how to measure DC current. In this guide we shall use this sensor to measure AC current. NOTE: This guide uses main voltages. Please handle with care In this guide, we...
READ MOREIn this guide, we shall interface ACS712 hall effect current sensor with STM32. In this guide, we shall cover the following: ACS712 Sensor. Connection. Driver Development. Code. Result. 1. ACS712 Sensor: The Allegro® ACS712 provides...
