Android Question Communication with Michroship PIC 16F1459

[alainb4a]

Hello,

I would like to communicate with a device based on a Microchip PIC 16F1459

Using UsbSerial and trying to understand UsbSerialDemo,I always have the following :

"Error opening USB port 1"

I tried version 2.3 and 2.4 with 115200 and 9600 Baud without any better results.

Do you know how to solve this problem?

Thanks in advance

Alain

What is the output of this example: https://www.b4x.com/android/forum/threads/usb-host-library.11290/#post-63127 ?

Hello Erel,

the output of usbdetails1 is:

I don't think that this chip is supported.

The compatible chips list: https://github.com/mik3y/usb-serial-for-android/wiki/Compatible-Serial-Devices
And the ones listed here: https://www.b4x.com/android/forum/threads/usbserial-library-2-0-supports-more-devices.28176/#content

Hello Alain, first of all it is Microchip not Microship (like in the title). If your device is enumerated as a HID device it will probably not be possible. But if your device is enumerated as a CDC device (Virtual COM Port) then you will be able to communicate with it using the USB Serial library.

You will have to add the VID/PID to the device_filter.xml file and detect your device as a Custom Device. If I remember well Silicon Labs CP2102 is a good driver for this kind of IC.

I already made this kind of communication with is little brother the 14 pins PIC16F1454. If you need more help then feel free to ask. And if you speak french I also do.

Merci beaucoup Toley
j'essaye tout ça et je vous tient au courant.

Hello,

Apres quelques test il semblerais sue je sois en HID (InterfaceClass : USB_CLASS_COMM (human interface).
Est t-il possible malgré ça de développer une application androïd ?

Merci toute sugestion est la bienvenue.

Malheureusement, il n'y a pas de librairies qui le permettent actuellement sous B4A.

Hi Alain,
If beside the USB port, your mController also has RS485/RS232 port, then you can connect it to HC-6 Bluetooth module and use the serial library in your App in the Android device.
If you only have USB port, then still you can use USB <> serial converter, and connect the Bluetooth module to the serial side of the
converter.. (normally it has the USB on one side and 4-pins on the other side for Vcc, Gnd, Rx and Tx, that you can directly connect to the 4-pin port of the Bluetooth module. (you will cross the Rx and Tx of both devices)

Thanks Beja, Toley

and whith other development tools for android is it possible ?

I don't know, this forum is dedicated to basic4 android and this is the only tool I use for android. Maybe if you seach the Market you can find an app than can communicate with this kind of device.

I don't think you can find a better platform then B4A..
B4A gives you the power of .net and Java combined.. you can embed Java (as is) in your code, beside the powerful string manipulation.
