It helps in interfacing with the BMP180 using simpler I2C APIs as well to parse the Humidity data. 2.DHT.h && DHT_U.h It is used for establishing a connection with the DHT11 sensor through its serial ...

Here, I connected the RF transmitter module, LED ... with I2C address 0x27. rf_driver (2000, 11, 12, 0): Configures the RF module (2000 bps baud rate, RX on pin 11, TX on pin 12). str_helmet, ...

This project includes a 12-button keypad interfaced with a host MCU via I2C or UART, designed to serve as a mini keyboard for embedded systems. The STM32L010K4T6 handles debouncing and key scanning, ...

-- Formula is: (25 MHz / 100 Hz * 50% duty cycle) -- So for 100 Hz: 25,000,000 / 100 * 0.5 = 125,000 CONSTANT c_CNT_100HZ : NATURAL := 125000; CONSTANT c_CNT_50HZ ...
