In this guide, we shall see what is the comparator peripheral and how in general the comparator works. In this guide, we shall cover the following: What is a comparator. Comparator peripheral in STM32L053. Developing the driver. Connection. Code...
READ MOREIn the second section of part 2 of parallel port emulation, we shall see how to read the data being transmitted and display the data on LCD. In this guide, we shall cover the following: Transmitter code modification. Receiver code. Connection of...
READ MOREIn the previous guide (here), we took a look at what is parallel port and successfully send byte of data using timer and DMA. In this guide, we shall add the strobe signal which will be an essential part in the next part of the guide. In this...
READ MOREIn this guide, we shall emulate the parallel output that had been used before to communicate with printers which eventually replaced with serial port and USB. This guide focuses on the output which will be useful in upcoming guide. In this guide...
READ MOREIn this guide, we shall develop a driver for external interrupt in STM32L053-Nucleo-64 board. In this guide, we shall cover the following: What is external interrupt. Developing external interrupt driver. Results. 1. What is External interrupt...
READ MOREIn this 15th part of board support package, we shall develop timer driver that will overflow each 1 second and toggle LED accordingly. In this guide, we shall cover the following: Developing the header file. Developing the source file. Main code...
READ MOREIn this first section of the fourteenth part of board support package on STM32F411, we shall develop the initialization function of I2C and build I2C bus scanner to get the address of the connected slave devices. In this guide, we shall cover the...
READ MOREIn this fourth section of the thirteenth part of board support package, we shall use the BSP of DMA to transfer data from the peripheral to memory using SPI and MPU9250. In this guide, we shall cover the following: Configure the DMA. Transfer...
READ MOREIn this third section of the thirteenth part of board support package, we shall use the BSP of DMA to transfer data from the memory to peripheral which is SPI in this case. In this guide, we shall cover the following: Enabling DMA for SPI...
READ MOREIn this second section of the thirteenth part of board support package, we shall develop the source code of the DMA driver and test the driver with Memory to Memory mode. In this guide, we shall cover the following: Adding the required functions...
READ MOREIn this twelfth part of Board Support Package, we shall develop the receiver part of SPI to achieve full duplex communication with slave device which is in this case, MPU9250 sensor. In this guide, we shall cover the following: Modification of...
READ MOREIn this eleventh part of Board Support Package (BSP), we shall develop SPI driver to send multiple bytes with timeout. In this guide, we shall cover the following: Developing the header file. Developing the source file. Code test. Results. 1...
