这是通过魔方生成的ATIM通道4输出PWM，为什么没有信号输出，不知道哪里不对，通道1、2、3都是正常的

引脚配置错误
/* PA9 ATIM_CH4 */
    GPIO_InitStruct.pin = FL_GPIO_PIN_9;
    GPIO_InitStruct.mode = FL_GPIO_MODE_DIGITAL;
    GPIO_InitStruct.outputType = FL_GPIO_OUTPUT_PUSHPULL;
    GPIO_InitStruct.pull = FL_DISABLE;
    GPIO_InitStruct.remapPin = FL_DISABLE;
    FL_GPIO_Init(GPIOA, &GPIO_InitStruct);
按照手册
    pa9 ch4 数字功能 应该是 2，需要改成FL_ENABLE    GPIO_InitStruct.remapPin = FL_ENABLE;
