1 Introduction
NUCLEO-WL55JC2 is a development board tailored by ST for the STM32WL series (STM32WL Nucleo-73 boards). It can be used to evaluate the full performance of the STM32WL55J.
The NUCLEO-WL5...
A long time ago, I thought about the reasons that limit the development of .Net Micro Framework. With the popularity of the Internet of Things and Cortex-M3, .Net Micro Framework should have more room...
I have recently made some small boards for practice, all of which were made with 5*7cm perfboards. I feel that soldering direct-insert components and dip-packaged chips is more flexible and easy to us...
As shown in , this is the CPU usage when compiling the 302R8 routine in the STM32Cube_FW_F3_V1.6.0 library. When compiling, the CPU is fully used and the mouse cannot be clicked. What is going on?...
