USB HID 发送数据babble detected怎么处理
本帖最后由 wdshuang09 于 2017-12-11 21:39 编辑芯片是STM32F103C8T6移值官方的USBHID，在主函数里调用：USB_SIL_Write(EP1_IN, (uint8_t*) data, 2);SetEPTxValid(ENDP1);
可以将数据发送出去，但改成发送数据长度不4就会出错
USB_SIL_Write(EP1_IN, (uint8_t*) data, 4);
SetEPTxValid(ENDP1);
提示：babble detected，是不是发送数据长度超了，应该怎么修改呀，需要修改哪几个点，请高手指点，

上传最大长度设为 2 ，当然不能上传4个数据
