STM32 connection to an Android device over USB CDC

[Michel Catrouillet]

Hi,

In order to demonstrate a remote basic GPIO management, I have built this package:

https://github.com/STMicroelectronics/STMCD_Android_BasicGpioDemo

For the USB CDC management inside Android, I have used usb-serial open source library, and added STM32 missing driver.

usb-serial is available here:

https://github.com/mik3y/usb-serial-for-android

This demonstration integrates:

• a User Interface embedded in an Android application
• a basic communication protocol over USB CDC class
• a basic Cortex M4 GPIO management Firmware running on Nucleo-F302R8, communicating with User Interface through STLINK.
• a basic Cortex M4 GPIO management Firmware running on Nucleo-F429ZI, communicating with User Interface through built-in USB.

This demonstration provides source files of:

• Android application,
• the Nucleo-F302R8 firmware,
• the Nucleo-F429ZI firmware.

Enjoy.

Hey folks,

If anyone is using Xamarin Android and would like to use the STM32 CDC driver that was written for the https://github.com/mik3y/usb-serial-for-android library, it has been ported to C# and added to the Xamarin Android compatible version of the library, available here: https://github.com/anotherlab/UsbSerialForAndroid.

We don't have any STM Nucleo devices to test the code on, but it's a line by line port from Java to C# and it should work identically to the driver when used with mik3y's library.
