Problem with response from device #71

Closed MrHazee closed 6 years ago

MrHazee commented 6 years ago

Hi there!

Im working on a project that involes Hid4java and a HID-device. Its working great in general but I have this little problem regarding the response time from my device. If I call hidDevice.read(data, 100): no respons. If i call hidDevice.read(data, 1500): Response but to slow. If i call just hidDevice.read(data): Extremely fast and nice response but im stuck in the function. Its blocked?! Any suggestions to solve this matter? Probably not a biggie but I have not that much experience so.. would appreaciate any help!

Thanks /Rasmus

Can you share what you did in case, somebody else has the same problem?

Actually Im not sure what caused the problem. But Im pretty sure it was not the API. Probably I messed the timing up between my custom tx/rx threads. It now works flawless with hidDevice.read(data,2000); ie very fast respons.
