腾讯物联网终端操作系统（TencentOS tiny）是腾讯面向物联网领域开发的实时操作系统，具有低功耗，低资源占用，模块化，安全可靠等特点，可有效提升物联网终端产品开发效率。TencentOS tiny 提供精简的 RTOS 内核，内核组件可裁剪可配置，可快速移植到多种主流 MCU 及模组芯片上。而且，基于RTOS内核提供了丰富的物联网组件，内部集成主流物联网协议栈（如 CoAP/MQTT/TLS/DTLS/LoRaWAN/NB-IoT 等），可助力物联网终端设备及业务快速接入腾讯云物联网平台。这是官网 https://cloud.tencent.com/product/tos-tiny，接下来开始移植。首先要准备一个带有基本外设的工程，有串口，LED灯就可以了，使用的是官方给的例子。下载TencentOS的源码，如下所示：
上面画框的是我们需要的部分，由于本次芯片是m0+的，所以在架构选择arm-v7a，删掉不用的部分，避免工程过大。接下来直接keil里面添加源码。如下所示：
源码添加完成后需要添加头文件路径
接下来特别重要的一步，需要选择C99mode ，不然编译的时候可以看到900个错误。
接下来需要对ht32f5xxxxit.h中的函数进行处理。
//void SVC_Handler(void)
//{
//}
/*********************************************************************************************************//**
* @brief This function handles PendSVC exception.
* @retval None
************************************************************************************************************/
//void PendSV_Handler(void)
//{
//}
/*********************************************************************************************************//**
* @brief This function handles SysTick Handler.
* @retval None
************************************************************************************************************/
void SysTick_Handler(void)
{
if (tos_knl_is_running())
{
tos_knl_irq_enter();
tos_tick_handler();
tos_knl_irq_leave();
}
}
接下来需要创建一个OS的配置裁剪文件，Tos_config.h
#ifndef _TOS_CONFIG_H_
#define _TOS_CONFIG_H_
#include "ht32.h" // 目标芯片头文件，用户需要根据情况更改
#include <stdio.h>

#endif
