stm32f103c8t6 demo\cdc_acm_hid_msc_template.c need modify usb_dc_fsdev.c USB_RAM_SIZE to 1024

#ifndef USB_RAM_SIZE
#define USB_RAM_SIZE 512
#endif

and hid endpoint get errors USB_REQUEST_CLEAR_FEATURE: [E/USB] ep:86 clear halt

导致hid设备出现感叹号，这个应该如何解决

谁让你改成1024的？这是硬件规定的，怎么能随便改？

sakumisu commented 2 years ago

fsdev不支持这个demo

超了就是超了，没办法，要么换芯片

OK，那F103C8T6就没法实现daplink v2.0的全部功能了。HID + CDC + MSC拖拽
