Hi !

   

I want to develop an Android app that communicates with a device using  a CY7C68053-56BAXI chip.

   

The chip uses the ReNumeration process (2 steps configuration).

   

Is the USB-Serial SDK for Android (found here : http://www.cypress.com/?rID=83110) appropriate to develop that kind of application ?

   

I already have the firmware file to load in the chip, I just don't know how to do it. So, are the necessary functions for loading a firmware on the chip, included in the SDK mentionned above ?

   

If not, what should I do ?

   

 

   

Even if I'm not sure that it's the proper SDK, I tried to run the application provided in it, on an Android tablet, to try communicating with the Cypress chip.

   

The problem is, I can't build the .apk because of an error in the native (C/C++) files of the SDK :

   

Here is the build log:

Do you know something about this error ? The config.h file is in the same folder as io.c, why can't the compiler find it ?

   

 

   

Thank you for your help.

By the way, I use the Android Studio IDE.

Hi again !

   

I've managed to bypass the error by replacing #include <config.h>  by  #include "config.h", in cy_libusb/io.c

   

I now have another problem: it doesn't find libusbi.h, in io.c:42:21  :  #include "libusbi.h"

   

libusbi.h is in the parent folder, so I tried #include "../libusbi.h", but it doesn't work either.

   

What can I do ?

   

 

   

Thank you.

I repost my previous questions to refresh the thread:

   

 

   

I want to develop an Android app that communicates with a device using  a CY7C68053-56BAXI chip.

   

The chip uses the ReNumeration process (2 steps configuration). So I need to load a firmware in the chip before being able to send commands to it.

   

Is the USB-Serial SDK for Android (found here : http://www.cypress.com/?rID=83110) appropriate to develop that kind of application ?

   

If not, is there anothe way that I can do this Renumeration process from an Android device ?

   

I already have the firmware file (to load in the chip), I just don't know how to do it.

   

 

   

Thank you,

   

Matthieu Heitz.
