B4J Question How to install Additional Libraries

[Rob_Wood]

Having problems finding and installing two libraries. UsbManager and ByteConverter libraries are listed in documentation, but I cannot find how to download and install. Please help

The B4A ByteConverter library is compatible with B4J

ByteConverter library

It's occasionally useful to be able to poke around in things as arrays of bytes so this library lets you do it. It can transform arrays of primitive types to and from arrays of bytes with the "endian-ness" of the conversion specified. If you need endian-ness you will either know about it or...

I don't know if there is a UsbManager for B4J. There is one for B4A but it is Android specific.

Thanks for your quick response. Is it possible to use FelUSBSerial with B4J? Also, while I can find all additional libraries in the documentation portion of the web site, is there an easy way to find where the Zip to download is located. I spent time looking for ByteConverter Library with no success. Sorry to take your time but it is frustrating when your quick response led me right to the correct place.

Is it possible to use FelUSBSerial with B4

I'm afraid not - that too is Android specific. What USB peripherals do you want to use? If it is a virtual COM port then jSerial should work as long as Windows can load the drivers for the USB device (assuming you are using Windows of course).

jSerial library

The jSerial library allows you to open and communicate with other devices through the computer COM ports. It can also be used to communicate with Bluetooth devices over a virtual com port. (jBluetooth library is now available: https://www.b4x.com/android/forum/threads/jbluetooth-library.60184/)...

I am trying to write a program to write to a Alpha Sign using FTDI through USB from desktop computer.

jSerial should work for you.
