In the previous guide (here), we saw how to configure the ADC with DMA and timer to trigger it periodically. In this guide, we shall see how to use the double buffer mode to increase the potential processing power of STM32F4. In this guide, we...
READ MOREIn the previous guide (here), we took a look how to transmit data over SPI bus using DMA. In this guide, we shall use DMA with SPI in full duplex to transmit and receive at the same time. This will free the CPU to do something else (not covered...
READ MOREIn the previous guid (here), we took a look at HM-10 module and how to connect it to STM32F4. In this guide, we shall use this module in full duplex to control LED and send strings from STM32F4 to a phone. In this guide, we shall cover the...
READ MOREIn this two part series guide, we shall interface HM10 BLE module with STM32 and control an LED and send string from STM32. In this guide, we shall cover the following: What is HM-10. Connection. UART setup. LED Setup. Time base setup. code. 1...
READ MOREIn the previous guide (here), we took a look at HC-12 RF module and setup the environment in STM32CubeIDE. In this guide, we shall continue the environment setup by initializing the user push button as external interrupt and library for HC-12. In...
READ MOREIn 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 this two part guide, we shall see how to interface 4×4 Keypad with STM32F411RE-Nucleo and develop the algorithm required to read the keypad. In this guide, we shall cover the following: Key structure. Reading keypad. Keypad pinout...
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...
