HAL Library 29- Analog to Digital converter for STM32Fxxx

Analog to digital converter library is out. It was a lot of time before I thought why I don’t have this basic library where anyone would use it. Now i exists. This library works on STM32F0xx, STM32F4xx and STM32F7xx based devices. Library Read more about new HAL libraries Features It uses basic polling for ADC complete Supports VBAT reading Does not get high sampling rates Meant for basic use

AM2301 Temperature and Humidity sensor 18

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
