这篇来学习下freeRTOS的移植。
一、下载源码
官网地址：https://www.freertos.org/
github下载地址：https://github.com/FreeRTOS/FreeRTOS/tree/202212.00
选择最新的版本
二、添加项目文件
在之前创建的项目上增加freertos
2.1、复制source文件复制到\midwares\FreeRTOS文件下
2.2、在工程中添加文件
2.3、添加头文件
2.4、修改FreeRTOSConfig.h头文件

}
void start_task(void *pvParameters)
{

taskEXIT_CRITICAL();
}

{
while(1)
{
printf("task1 running ...\r\n");
vTaskDelay(1000);
}
}

{
while(1)
{

}
}

#include "lcd.h"
#include "sram.h"
#include "timer0.h"
#include "led.h"
#include "touch.h"

stc_touchpad_data_t touchdat;
int32_t main(void)
{
uint16_t u=0;
uint16_t cord[6]={WHITE, BLUE, BRED, GBLUE, RED, YELLOW};
/* Register write enable for some required peripherals. */
LL_PERIPH_WE(LL_PERIPH_GPIO | LL_PERIPH_FCG | LL_PERIPH_PWC_CLK_RMU | LL_PERIPH_EFM | LL_PERIPH_SRAM);
BSP_CLK_Init();
/* EXCLK 60MHz */
CLK_SetClockDiv(CLK_BUS_EXCLK, CLK_EXCLK_DIV4);
DDL_PrintfInit(BSP_PRINTF_DEVICE, BSP_PRINTF_BAUDRATE, BSP_PRINTF_Preinit);
BSP_IO_Init();
BSP_LED_Init();
BSP_LCD_IO_Init();
init_led();
init_touch();
init_lcd();
init_sram();
init_timer0();
SysTick_Init(1000U);
LL_PERIPH_WP(LL_PERIPH_GPIO | LL_PERIPH_FCG | LL_PERIPH_PWC_CLK_RMU | LL_PERIPH_EFM | LL_PERIPH_SRAM);
POINT_COLOR=RED;
LCD_Clear(WHITE);
//sram_test();
create_task();
for (;;)
{
}
}
三、程序运行
串口输出两个线程的打印结果
