Hi,
I'm using the stm32f746g-discovery board with the Keil USB HID example. I can connect to the USB HID device with a UWP app using the HidDevice class.Is it also possible to use the UsbDevice class to connect to the board when using the Keil USB HID example? I want to try to use interruptOut to connect to the board and this is only possible with the UsbDevice class.
The UWP app I made with the UsbDevice class does not seem to connect to the USB of the discovery board (no problem with the HidDevice class UWP app).
Am I trying something that is impossible or am I doing something wrong with the connection?
I'm using the example code from Microsoft to connect:
private async void OpenDevice() { UInt32 vid = 0x045E; UInt32 pid = 0x0611; string aqs = UsbDevice.GetDeviceSelector(vid, pid); var myDevices = await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(aqs); try { usbDevice = await UsbDevice.FromIdAsync(myDevices[0].Id); } catch (Exception exception) { ShowStatus(exception.Message.ToString()); } finally { ShowStatus("Opened device for communication."); } }
With the correct vid & pid (works with HidDevice class).
I'm new to USB implementation and trying to learn.
thx
