In this guide, we shall see how to interface ADXL335 Accelerometer sensor with STM32F4. Since this sensor is analog based sensor, we shall use DMA to handle the data from the adxl335. To setup multichannel ADC with DMA, please refer to this guide...
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 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 (here), we took a look how to configure the UART to transmit and receive data to/from PC using DMA. The limitation that we shall wait until the buffer is filled before we print the the received characters. In this guide, we...
READ MOREIn the previous guide (here), we took a look how to configure the UART to transmit data to PC using DMA. In this guide, we shall configure the UART to receive characters using DMA. This guide shall cover the following: Configure UART for DMA RX...
READ MOREIn the previous guide (here), we took a look at the continuous mode for ADC module of STM32L0. In this guide, we shall see how to configure the ADC to work in DMA mode with two channels enabled. (Can be expanded to the desired number of...
READ MOREIn the previous guide (here), we saw how to configure the required peripherals. In this guide we shall see how to develop the algorithm required to decode the data. In this guide, we shall cover the following: Decoding algorithm. Code. Demo 8...
READ MOREIn the previous guide (here), we took a look how to control two LED using touch toggle switches. In this guide, we shall see how to control LEDs brightness using sliders. In this guide, we shall cover the following: LED PWM driver code. Nextion...
READ MOREIn the pervious guide(here), we took a look at the WS2812 and they work and type of communication required. In this guide, we shall see how to use PWM in DMA mode to control those LED. 4. Setting up the PWM and DMA: Since we shall use TIMER 1 of...
READ MOREIn the previous guide (here), we took a look at how to implement the PID controller programmatically. In this guide, we shall use simple case study to control the speed of a DC motor. In this guide, we shall cover the following: What is speed...
READ MOREIn the previous guid (here), the timer interrupt was introduced with rate of 1Hz to blink the LED.In this guide, it shall present the usage of timer in PWM mode. This guide shall cover the following: What is PWM. Configure the timer and GPIO to...
READ MOREIn the previous guide (here), we took a look how to configure the ADC to use DMA with multiple channel. In this guide, we shall use timer to trigger the ADC each 2 second and display the result on serial terminal. In this guide, we shall cover...
