In the previous guide here, we took a look how to configure a pin as output and blink an LED. In that guide, we used crude delay of for loop to blink the LED. In this guide, we shall use timer to create precise delay ranging from 1 millisecond...
READ MOREIn this guide, we shall use MCP4131 digital potentiometer with STM32 to vary the potentiometer using software. In this guide, we shall cover the following: MCP4131. MCP4131 connection with STM32F4 SPI Code. MCP4131 Code. Code. Demo. 1. MCP4131: A...
READ MOREIn the previous guide (here), we saw how to configure a GPIO pin as output. In this guide, we shall configure another pin an input to read from push button. In this guide, will cover the following: Input modes. Develop GPIO Input driver. LED...
READ MOREIn this new guide series, we shall develop some drivers for the most widely used STM32 which STM32F103 aka bluepill. In this guide, we shall cover the following: Setting up the environment Getting the required documents. Developing GPIO output...
READ MOREIn this guide, we shall use STM32 to develop a driver to set and get the time store in the DS3231. In this guide, we shall cover the following: DS3231 Module. Connection with STM32F411 Nucleo-64. Developing the header file. Developing the source...
READ MOREIn the previous guide, we saw how to configure TIM2 to work in output compare mode. In this guide, we shall use timer to reach from an encoder. In this guide, we shall cover the following: What is encoder Required parts and connection Configure...
READ MOREIn part 1 (here), we saw to configure the SPI and other parameters required for ADXL345 operation in SPI mode. We shall continue from here: 8. adx345 read/write functions: In order for the adxl345 to distinguish between SPI and I2C, when sending...
READ MOREIn the previous guide (here), we saw to configure the ADXL345 to work in I2C mode and get the acceleration values. In this guide, we shall use the same sensor is SPI mode. In this guide, we shall cover the following: Connection. Pin...
READ MOREIn this guide, we shall see how to interface STM32F4 with acceleration sensor ADXL345 using I2C mode. In this guide, we shall cover the following: Feature of ADXL345. Developing the driver. Code. Results. The ADXL345 is a small, thin, ultralow...
READ MOREIn the previous guide, we saw how to configure TIM2 to work in output compare mode. In this guide, we shall use timer to reach from an encoder. In this guide, we shall cover the following: What is encoder Required parts and connection Configure...
READ MOREIn the previous guide, we took a look at the internal DAC of STM32F7 (here) and we where are able to generate sawtooth using DAC and software trigger. In this guide, we shall use timer and DMA to generate sinewave using DAC. In this guide, we...
READ MOREIn this guide, we shall take a look at the internal DAC of STM32F767 and develop software triggered DAC to generate triangle wave. In this guide, we shall cover the following: What is DAC Configure DAC Generate wave form from DAC Results 1 What...
