In 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...
READ MOREIn the third part of creating a library for ADXL345, we shall study the interrupt capabilities of ADXl345 and improve the driver to utilitize the usage of the interrupt of STM32. In this guide, we shall cover the following: 8. Interrupts of...
READ MOREIn the previous guide (here), we took a look at why we should use DMA to acquire data from ADC in multichannel and let the ADC trigger itself each time the conversion is completed. In this guide, we shall use timer to trigger the ADC to start the...
READ MOREIn the pervious guide (here), we took a look how to configure the DMA with ADC to acquire data from single channel. In this guide, we shall see why DMA is essential when deal with multichannel in ADC and how to configure the ADC and DMA to work...
