In this revised guide on SPI with DMA on STM32F103, we shall transmit packet of data using DMA without CPU intervention. In the previous guide (here), we took a look how to configure the SPI to transmit data using polling mode. In this guide, we...
READ MOREIn the previous guide (here), we took a look at RS485 and ModBus in general. In the second part, we shall interface MAX485 and develop driver to transmit data. In this guide, we shall cover the following: MAX485. Connection. Developing driver for...
READ MOREIn this guide series, we shall take a look at RS-485 and Modbus-RTU and develop driver to communicate with RS-485 enabled device. In this guide, we shall cover the following: What is RS-485. What is Modbus-RTU. Environment Setup. 1. What is...
READ MOREIn this guide on the internal RTC of STM32G0, we shall configure the RTC and display the time and date on the serial terminal. In this guide, we shall cover the following: Internal RTC. Driver development. Results. 1. Internal RTC: The RTC...
READ MOREIn this guide, we shall see what is embeetleIDE and test it. In this guide, we shall cover the following: What is Embeetle IDE. Getting started with Embeetle IDE. Results. 1. What is Embeetle IDE: Embeetle IDE is a clean and efficient...
READ MOREIn the previous guide (here), we were able to transmit data over I2S using DMA, in this guide, we shall initialize the CS43L22 which is stereo DAC. In this guide, we shall cover the following: Enabling circular mode for DMA. Header file...
READ MOREIn this guide, we shall see how to configure the DMA to transfer data from one memory location to another without using the CPU. In this guide, we shall cover the following: What is DMA. Why DMA in Memory to Memory. Driver Development. Results...
READ MOREIn the previous guide (here), we took a look how to configure the I2S and transmit data using poling mode. In this guide, we shall use DMA to transfer data over I2S bus. In this guide, we shall cover the following: I2S Configuration. DMA...
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 the DMA to receive data over SPI from a slave device (MPU9250) in this case. In this guide, we shall cover the following...
READ MOREIn the previous guide (here), we took a look what is I2S and how it works and it’s features. In this guide, we shall configure the I2S and send data using polling mode. In this guide, we shall cover the following: I2S Clock Configuration...
READ MOREIn the previous guide (here), we took a look at the SPI interface and how to configure the STM32G0 to communicate with SPI slave device (MPU9250) in polling mode. In this guide, we shall transmit data over SPI bus using DMA. In this guide, we...
READ MOREIn this guide series, we shall cover the I2S peripheral of STM32F407 and its feature. In this guide, we shall covet the following: What is I2S. Feature of I2S of STM32F407. Feature of CS43L22. Environment Setup. Set the core speed to 168MHz...
