How to precisely measure microseconds with STM32

I received this apparently simply question from a reader of this blog: how can I delay a fistful of microseconds in STM32? That is, how to measure microseconds precisely in STM32? The answer is: there are several ways to do this, but some methods are more accurate and other ones are more versatile among different MCUs and clock configuration. Let's consider …

Adding ethernet connectivity to a STM32-Nucleo

One drawback of the Nucleo ecosystem is the lack of a version with ethernet connectivity or a dedicated shield officially supported by ST. There are 90 different STM32 MCUs available that provide an Ethernet MAC interface (this means that only an external ethernet transceiver - also called phyter - and few other things are required to bring your MCU to the …

Getting started with STM32F746G-DISCO

ST Microelectronics recently expanded its portfolio of STM32 microcontrollers with the new STM32F7 family. These are the new best-in-class MCUs from ST, with a Cortex-M7 core able to run up to 216Mhz (future releases will run up to 400Mhz with 2000 CoreMark index), with an internal flash up to 1Mb and 360Kb of RAM. STM32F7 is also able to run …
