if((timex%200)==0) { u3_printf("cmd=0&msg=ping");//心跳包 timex=0; }

这段代码是在进行心跳包的发送，其中`timex`表示时间计数器，每200ms进行一次心跳包的发送。在发送心跳包时，会向服务器发送一个`cmd=0&msg=ping`的请求，其中`cmd=0`表示心跳包的命令，`msg=ping`表示心跳包的内容为"ping"。这样可以保持客户端与服务器之间的连接不中断，以便进行实时通信。

以下是修改后的标准库代码：

void atim_timx_cplm_pwm_init(uint16_t arr, uint16_t psc)
{
    TIM_HandleTypeDef g_atimx_cplm_pwm_handle;

    sConfigOC.OCIdleState = TIM_OCIDLESTATE_RESET;
    sConfigOC.OCNIdleState = TIM_OCNIDLESTATE_RESET;

    HAL_TIM_PWM_ConfigChannel(&g_atimx_cplm_pwm_handle, &sConfigOC, ATIM_TIMX_CPLM_CHY);
