How to get data from USB?

[Kiril]

Good day!

My device is connected to USB-port and all the time sends to PC a byte-code.

How can I receive this data in my java using Pundit library?

What Class and method response for receiving such information?

I tried to find this functionality but I couldn't.

Thank you, Rishi!.

Hi Kiril,

Does your device open a COM-port on your PC or is it "just" a USB device?

You can check this in the device manager if you're using windows.

If it does not create a COM-port then I guess you have to use something like libusb to directly access the USB-port.

Cheers,

Andreas

Thanks Andreas for your reply.

I have both cases.

When you wrote about libusb did you mean this library? http://libusb.info/

Please can you suggest how integrat C library into java-project?

Thank you!

and by the way... should I use SerialComManager and SerialComHID in COM-port case?

What difference between SerialComUSBdevice and SerialComUSBHIDdevice?

- There are various options/softwares. Please provide details about your hardware and application use-case.

-  SerialComUSBdevice represents a usb device and SerialComUSBHIDdevice represents a usb-hid device like CP2110

I'm working with accelerometer and it sends to USB-port byte-code packages according to it's registers.

Which library can receive this data? Maybe you can write somekind of code example?

Thank you, Rishi!

Hi Kiril,

An accelerometer typically sends data using either i2c or uart protocol. Please provide link to accelerometer datasheet so that i can understand give example to use it.

[Kiril]

I work with MPU9250 accelerometer. 

Here is pdf-documentation. 

https://cdn.sparkfun.com/assets/learn_tutorials/5/5/0/MPU9250REV1.0.pdf

Also in near future I will have to process the GPS-data from GPS-receiver by UBX protocal. Most likely I will use U-Blox 8 receiver model.

Here is it's documentation.

This accelermoter does not have USB. Are you using usb-uart converter like FT232 or CP2102.

Please share your connection block diagram computer <---> device

[Kiril]

Sorry for long response. 

I use Teensy 3.6. with MK66FN2M0VMD18 microcontroller. In practice windows sees it like usb device and creats it's own COM-port for data exchange, so windows use somekind of it's own-converter. 

Here is Teensy 3.5 & 3.6 Schematic:

Thanks for info. Is teraterm working https://ttssh2.osdn.jp/index.html.en with teensy in your computer.

[Kiril]

ok, and how can I use this util for my Java code?

Did I understand correctly that I can't use SerialPundit library for data exchange between my device and PC?

- serialpundit library can be used for your application

- using teraterm is to make sure that drivers for your board are installed and you become familiar with usb-uart ports

- do not connect teensy board and run this https://github.com/RishiGupta12/SerialPundit/blob/master/tests/test1-list-ports/src/test1/Test1.java

then connect teensy board and run the above test.

You will get COM Port and then use other APIs of serialpundit.

[Kiril]

Thank you!

I will try it.
