VBrain Coming ... the ARM Cortex M4 revolution

 

 

 

Dear Friends,

after 2 month of test I'm happy to inform you that the VBrain is ready to fly.

The platform is a result of 4 years of work on ARM autopilot platform. It's last evolution of Multipilot32 platform. I'm very happy that this is the year of ARM and we are here to present our last creation : Simple , Smaller and Ready to Use.

VBrain is a good choose for OEM ready to use hardware platform.

The VBrainautopilot features include:

  • 168Mhz ARM CortexM4F microcontroller with DSP and floating-point hardware acceleration.
  • 1024KiB of flash memory, 192KiB of RAM.
  • MEMS accelerometer and gyro, magnetometer and barometric pressure sensor.
  • 8 RC Input standard PPM , PPMSUM , SBUS
  • 8 RC Output at 490 hz
  • 1 integrated high speed data flash for logging data
  • 1 Can bus 2 i2c Bus
  • 3 Serial port available  one for GPS 1 for serial option 1 for serial telemetry.
  • 3 digital switch (ULN2003).
  • Jtag support for onboard realtime debugger.
  • 1 Buzzer output.
  • 1 Input for control lipo voltage
  • Include in the standard Vbrain Package there is VBrain GPS module , the module support MTEK 3329 gps , Ublox module , Fastrak IT600. On the module is available optional magnetometer. You can disconnect the board and put it far from brushless motoros to solve the problem of noise on mag signal.
  • Physical Dimension 6x4 cm
  • Will be available a case

 

It's first Universal Arm hardware platform . On it is available different kind of firmware : Open or Closed source . The main firmware available is Arducopter32 , last revision is 2.7 In the next day will be available a full fly test.
This platform is fully compatible with different kind of RTOS : FreeRtos , ChibiOS , Nuttx , CooxOS .

Our first target when start to develop our hardware platform 2 years ago was to develop a simple and powerfull ide.

We develop VRIDE PRO that is a special distribution customize by FoxTeam and LaserLab guys. The Ide use Eclipse as Editor, GCC as compiler , GDB and OpenOcd as Debugger.

This is the link of ready to use Ide:

http://code.google.com/p/multipilot32/downloads/detail?name=vroboti...

The ide support different kind of workspace and library. Our first target was porting all arduino and APM api to ARM platform.

 

The supported firmware are Arducopter32the last revision available is 2.7 the status of firmware is ready to fly .

The Workspace with last revision of code is available here :

http://code.google.com/p/multipilot32/downloads/detail?name=ACopter...

Our Team are working also on PX4 enviroment , first target was to port Arducopter32 on PX4 and PX4 enviroment to Vbrain and MP32Fx platform.

The hardware is compatible also with other opensource firmware as AutoQuad AeroQuad and OpenPilot. A lot of work are doing on IDE and firmware to share it on our platform.
We try to work to a new Opensource Standard based on high performances STM32F4 micro controller.

 

The price for VBRAIN with GPS Board (MTEK 3329 rev) developer revision  is 199 euro.

It's also available a ready to use board with 3 days of support by team viewer at 270 euro.

There is also available a oem version of product.

We are Ready for pre order the first batch of production will be available in 3 weeks some sample is yet available.

Great work Roberto!

Today i implemented the support for analog input in vbrain. Now I'm working in revision Arducopter32 rev 2.7.1 with some patch from Alberto on analog input API and Emile on MPU6000 configutation .

So now is possible to connect the lipo output directly to Voltage Input until 17 volt and see on Mission planner the voltage status.

Is yet implemented the code for warning with a buzzer when the voltage going down and also the info by led about the status of flight ... i need to test all this functionality.

I'm doing other check on the priority of interrupt .

The first beta version of 2.7.1 will be available on repo in some hours .

Hi Roberto,

What kind of buzzer can be used? I have found 2 types, one that make a tone if you connect to 5v, and an other that have a pin for tone signaling. A ebay url?

I want to connect the lipo and use a buzzer to indicate low voltage..

Perfect you VBRAIN coming don't worry we lost some time to check the problem on JTAG but we found that was because the new micro need the new firmware from ST for swd comunication. Now all work perfect.

You need to remove only +5v on esc could be better mantain GND.

Hi Roberto, do you remove only the +5v from the ESC's or +5V and GND (use only signal) ?
I know that you must keep +5V from one, or use an UBEC.
Have tested my new quad (FPV Quad II) using MP32F4/NAVY2012 and it is great :-) Hope my VBrain arrives soon - I'm modifying the quad to support VBrain (holes, cables..)

Hi Oyvind,

yes the front is where you have inputs and leds ...

Witch end is the front on the Vbrain? The one with the inputs?

Comment by Oyvind Amundsen on July 30, 2012 at 10:23pm

Do you have an image, showing the meshurements for the mounting holes on the VBRAIN, and the GPS module? So i can prepare my new FPV Quad II ?

Comment by Oyvind Amundsen on July 30, 2012 at 8:49am

Is the magnetometer included in the developer revision?

Great news Roberto, and great work Stefan!

Have sent a Mail to virtualrobotix about the VBRAIN
