UART Tx data using Poll Interrupt and DMA in STM32
The data is transmitted in blocking mode i.e the CPU will block every other operation until the data transfer is complete.
Interface Stepper motor with STM32
Stepper motors generally comes along with an IC ULN2003. This IC is used to drive motor because microcontroller pins are unable to provide sufficient current to drive these motors.
using DHT11 sensor with STM32
DHT11 digital temperature and humidity sensor is a composite Sensor contains a calibrated digital signal output of the temperature and humidity. Today in this tutorial we will be using DHT11 sensor with STM32.
ADXL345 tap detection
Set the TAP THRESHOLD to 2.5g. To do that we need to write 40 (2.5/.0625) to the THRESH_TAP Register. This means that you need at least 2.5g acceleration in Z AXIS in order for the tap to qualify as TAP.
