preface All operations during the experiment must be careful and careful. Do not rush to operate. The error of the final experiment operation is often caused by the error of a small step. Experimental requirements Learn the embedded real-time operating system (RTOS), take uc/OS-III as an example, transplant it to stm32F103, and build at ...

For the windows system I used before, the newly purchased M1 just arrived a few days ago. I encountered some problems when running the nacos container with docker desktop, so I make a record. I also hope my experience can help more people. First, the nacos image on the docker hub official website does not support the arm architecture. You need ...

1, SPI (serial peripheral interface) 1.1 definition of SPI SPI (Serial Peripheral Interface) is the Serial Peripheral Interface. SPI is a high-speed, full duplex, synchronous communication bus, and only occupies four wires on the pins of the chip, saving the pins of the chip. SPI is a ring bus structure, which is composed of ss(cs), sck, ...
