Library 37- BMP180 pressure sensor for STM32F4

BMP180 is a digital pressure sensor, with builtin temperature sensor. Its range is between 300 and 1100 hPa (0.3 to 1.1Bar). In relating to the sea level, this is +9000 to -500 meters. Sensor works with I2C communication at 100kHz. If you want sensor from ebay, here is one link. Sensor is quite bad created, because if you want to read pressure, you first need to read current temperature for pressure calculation. To read temperature you have to wait at least...

Library 25- AM2301 (DHT21) sensor for STM32F4

AM2301 or DHT21 is a digital sensor for measure temperature and humidity. It has temperature resolusion up to .1 degree and accuracy to .5 degree celcius. Humidity has .1% resolution and 3% accuracy. This is quite good. Library Features Read temperature from sensor Read humidity from sensor Dependencies CMSIS STM32F4xx STM32F4xx RCC STM32F4xx GPIO TM TM DELAY TM GPIO defines.h

All STM32F4 libraries

Because there is a lot of libraries I have done, I will make a table with all of my libraries at one place. When new library will be created, it will be posted here. These libraries work on both Discovery boards, if not, it will be specified. Actually, libraries should work on STM32F4xx series of microcontrollers if they have peripherals that are need for library. All STM32F4xx MCUs don’t have everything inside. 🙂 Libraries are tested on my 4 STM32F4...
