usb_hid.end() #33

Closed emtark closed 4 years ago

emtark commented 4 years ago

As requested by hathach on the forums - https://forums.adafruit.com/viewtopic.php?f=25&t=154636#p770791

Are we able to implement a end/detach function? Similar to existing request https://github.com/adafruit/Adafruit_TinyUSB_Arduino/issues/13

I'm using SAMD51 and unable to resume USB functions after returning from sleep/standby. I believe closing the connection, then sleeping, then reconnecting after waking up is the go.

Cheers, emtark.

Can you provide your simplest sketch that could reproduce the issue with a bit of explanation on before and after behavior of sleep/standby statement within the sketch.

@emtark USBDevice detach() & attach() can be used to physically disconnect/reconnect usb. Please try it out to see it works for you. https://github.com/adafruit/Adafruit_TinyUSB_ArduinoCore/blob/master/Adafruit_USBD_Device.h#L84

Works perfectly - thanks :) On another note, (if required I can move to a new thread) void hid_report_callback(uint8_t report_id, hid_report_type_t report_type, uint8_t const* buffer, uint16_t bufsize) { This function fires on my PC when the USB keyboard example is ready to send data -but never called on Android. Is there another method I can use to ensure the Android OS is ready to receive USB HID keyboard data?

Close since it solves op issue pleas. For hid callback it fires when there is related event. Please check out its contents for reported events.
