What is current sinking and sourcing? Read the article on Current Sourcing and Sinking to find out.
The tutorial on how to fit a new microcontroller to an Arduino Uno board shows how to remove the old IC and replace it with a new one.
Find out how to program STM32 microcontroller evaluation boards using the built-in ST-LINK in Linux. The tutorial uses the STM32 Value Line Discovery board from ST Microelectronics and Ubuntu Linux.
At first glance, it is not easy to understand how the STM32F100 range of microcontrollers from ST Microelectronics is arranged. This article explores the similarities and differences between members of the STM32F100 family.
STM32 ARM Cortex-M3 microcontroller from ST Microelectronics can be programmed in Windows without the need of commercial programming tools or the need to install any toolchain.
Using the free STM32 ST-LINK utility software from ST, STM32 microcontrollers can be programmed using an external ST-LINK (e.g. the ST-LINK/V2) or using the embedded ST-LINK that can be found on ST evaluation boards such as the STM32 Value Line Discovery kit.
This tutorial on the Starting Electronics website explains how to install and use the ST-LINK utility software.
