In the second part of PCA9685 PWM module guide, we shall create the library that allow us to set the frequency and control the duty cycle of each individual channel. In this guide, we shall cover the following: 6. Creating the Header and Source...
READ MOREIn this guide, we shall see how to build a library to PCF9685. In this guide, we shall cover the following: 1. Introduction: The PCA9685 is a versatile 16-channel, 12-bit PWM controller widely used in applications requiring precise control of...
READ MOREIn the second part of the PCF8591 library, we shall build the library to interface the module with STM32F4. In this guide, we shall cover the following: 4. Creating the Header and Source File: After the project has been generated by STM32CubeMX...
READ MOREIn this two part series guide on how to create a library for PCF8591 AD/DA (Analog to Digital/ Digital to Analog) that can be used with any microcontroller (STM32F4 in this case). In this guide, we shall cover the following: 1. Gathering the...
READ MOREIn this guide, we shall use timer to generate interrupt for precise time control for our application. In this guide, we shall cover the following: 1. What is Timer Interrupt: A timer interrupt in a microcontroller is a mechanism where...
READ MOREIn this guide, we shall use the DMA to update the duty cycle of the PWM to generate custom waveform like sinewave etc and the benefits of such approach. In this guide, we shall cover the following: 1. Why Update PWM Duty Cycle using DMA: Using...
READ MOREIn the second part of creating a library for SPI sensor, we shall construct the source and header file to interface the sensor with STM32F4. In this guide, we shall cover the following: 4. Creating the Header and Source File: After the project...
READ MOREIn the second part of timer series on STM32H5, we shall use timer in output compare to blink the LED using hardware level rather than software. In this guide, we shall cover the following: 1. What is Output Compare Mode: The Output...
READ MOREIn the first part of timer series on STM32H5, we shall use the timer to generate PWM signal to control the brightness of the LED connected to one of the timer channels. In this guide, we shall cover the following: 1. What is PWM: Pulse-width...
READ MOREIn this guide series, we shall see how to create library for SPI sensor based to acquire data from MPU9250. In part 1, we shall cover the following: 1. Gathering the Required Data: The MPU9250 has two documentation, first one is the specification...
READ MOREIn the previous guide (here), we took a look how to configure DAC and we used polling mode to generate waveform using the DAC. In this guide, we shall use timer and DMA to generate faster waveform while maintaining maximum performance. In this...
READ MOREIn this guide on DAC (Digital to Analog Converter), we shall see the feature of the DAC on STM32H5, the functional block diagram and how to develop the driver using STM32CubeMX. In this guide, we shall cover the following: In electronics...
