This course video is a paid course which covers the introduction of RISC-V processor ISA and interrupt mechanism, GD32VF103 chips and peripherals, development tools and software libraries. In terms of application, take FreeRTOS as an example to introduce the porting and booting of a FreeRTOS on RISC-V, and explain the basic use of FreeRTOS through examples, including task creation, interruption of interaction with tasks and communication between tasks. And through the visual RTOS analysis tool – Tracealyzer, you can intuitively view the behavior of RTOS in a multitasking environment.
