In this guide, we shall develop driver to measure the frequency and duty cycle of a signal. In this guide, we shall cover the following: What is PWM input mode. Required steps. Driver. STM32 Connection Code. Results. 1. What is PWM Input Mode...
READ MOREIn part 1 of input capture guides, we shall see how to use input capture to measure the distance from an ultrasonic (HC-SR04) and display the measured distance on the serial terminal. In this guide, we shall cover the following: What is input...
READ MOREIn this guide, we shall take a look at the thermocouple and how this type of sensor works and use MAX6675 thermocouple to measure the temperature. In this guide, we shall cover the following: Thermocouple typeK MAX6675. Connection MAX6675 with...
READ MOREIn 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 the second section of the fourteenth part of I2C BSP, we shall develop functions that will communicate with slave devices to write/read to/from MPU9250. In this guide, we shall cover the following: Updating the header file. Updating the source...
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...
