Hi,
I am trying to implement a basic usb device which will include both a cdc endpoint and hid endpoint, however was wandering if there are any example of usb and hid devices implementaions, i am running on an nucleo wb55 for development purposes and so far my main.c is attached bellow however line 76 usbus_hid_submit(&hid, buffer, sizeof(buffer)); results in errors when trying to compile,
more specifically: errors in format /Applications/ARM/bin/../lib/gcc/arm-none-eabi/10.3.1/../../../../arm-none-eabi/bin/ld: DWARF error: section .debug_str is larger than its filesize! (0x80d9e vs 0x55e08)
with varying values at the end of each line
followed by /Users/elliot/Documents/code/riot-tests/LED/bin/p-nucleo-wb55/application_test_app//main.o:/Users/elliot/Documents/code/riot-tests/LED/main.c:97: undefined reference to 'usbus_hid_submit' something which should be included from #include "usb/usbus/hid.h"
Anyone able to shed light on what error i have made here or wether there are some good hid example for riot-os for example as the device acting as a keyboard?
Regards Elliot
