[GD32F310 development board trial] GD32F310 porting FreeRTOS
Project address: https://github.com/kings669/GD32F310-FreeRTOS
Environmental description
First, let me explain my environment:
The version of keil5 I use is V5 36. The computer system is WIN10, and the firmware library version used is the latest version 2.2.0 downloaded from the official website (download address of the official website: http://www.gd32mcu.com/cn/download/7?kw=GD32F3 ), the FreeRTOS version I transplanted is v202112 00 (official website download address: https://www.freertos.org/a00104.html)
Development board information
Let's take a look at this development board:
GD32F310K-START evaluation board uses GD32F310K8T6 as the main controller. The LED pin is PA8, which we will use later.
We are looking at the Flash and RAM sizes of 64KB and 8KB respectively. We'll be at freertosconfig Set the size in H.
Transplantation process
You can refer to the materials in my project. All the required documents are placed in the doc folder.
Set up the folder and order the name:
We put the files of FreeRTOS in the Middleware middleware folder.
Downloaded FreeRTOS folder:
We just choose FreeRTOS. There is no need to use Plus. All the folders we need are in FreeRTOS. Copy it to our own project file.
We put the downloaded firmware library and CMSIS files in the Drivers folder we built.
Next, keil5 related settings:
1. Predefined: remember to check C99 support and add header file path.
2. Add files in keil5 according to the of the folder
A little note here is: port C is the file that selects the path in the figure (because our chip is M4 kernel), and we choose heap for memory management_ 4.c
So far, we still lack a FreeRTOS configuration file, freertosconfig h;
The content is:

Lighting test
After looking at the official routine, I'm still a little not used to it. I'm used to the writing of structure. So I've rewritten here and intend to finish the following peripherals one by one. Those who are interested can pay attention to the project.
The lamp pin is PA8

Thank you for the development board provided by the Jishu community. This is also the first time I use GD32. STM32 has been used before. In fact, the domestic 32 board is very good. Although the ecology of STM32 is indeed speechless, with tools such as CubeMX, it is not necessary. Considering the current price of STM32, I think we can support domestic production more. The ecology of MCU also depends on our developers. The ecology depends on our construction together.
