OTA introduction: The full name of OTA is over the air. In embedded systems, it refers to the online software upgrade of an embedded system. As for MCU system, it is an online update of Firmware for the whole MCU, so it is also called FOTA. DFU is also called Device firmware upgrade. All have the same meaning. OTA is used here. General MCU gene ...

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 ...

This paper mainly describes how to use STM32F103C8T6 to transplant uCOSIII operating system, build three tasks, control the LED on-off in 1s and 3s, and send "hello uc/OS! Welcome to RTOS multitasking environment" through serial port in 2s cycle. In addition to mastering the Keil simulation and debugging code function, SaleaeLogic16 i ...
