HAL Library 29- Analog to Digital converter for STM32Fxxx 1

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

Library 39- Power consumption modes for STM32F4

For library 39, I made a low power modes library. This allows you to simple put STM32F4 into SLEEP, STOP or STANDBY mode. Point of this modes is simple. You want decrease current on device. If you are working on battery project, this will be very helpful. You can set current down to about 2uA with proper low power mode. I will tell you only the highlights of all 3 power down modes in this post. For detailed informations, check ST’s...

Library 06- AD Converter on STM32F4

In this tutorial I will talk about ADC (Analog to Digital Converter). AD converts analog voltage to digital number, that can be used in microcontrollers. STM32F4xx MCUs have up to 3 ADCs of which every has 19 channels. 16 external channels, connected to IO pins 3 internal channels Vbat Voltage on battery pin for RTC Temp sensor unusable for measure temp,only for measure difference in temperature because it can fail up to 45°C Vref Voltage reference for ADC Below is table...
