In 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...
READ MOREIn this guide, we shall use DMA to offload the CPU from acquiring the data from ADC and improve the performance of the MCU. In this guide, we shall cover the following: 1. STM32CubeMX Modification: Open adc_single.ioc file as following: Next...
READ MOREIn part 2 of building library for ADXL345 sensor, we shall construct the header file and source file to interface the sensor with STM32F4. In this guide, we shall cover the following: 4. Creating the Header and Source Files: After the project has...
READ MOREIn this guide, we shall use the interrupt of the ADC to acquire the ADC data without waiting for the conversion to be completed. In this guide, we shall cover the following: 1. Modification to STM32CubeMX: Open adc_single.ioc file as following...
