Arducopter NG and Multipilot 2.0 / Ardupilot32 #1 Weekly Updates

[Roberto Navoni]

Hello everyone,
a year and a half ago came Multipilot 1.0 an inertial platform for applications and semi-professional hobby. After the excellent results obtained from the marketing of these cards, and participation in development projects as open source and Aeroquad Arducopter and 'born www.virtualrobotix.com community.
Today our community is proud to present the evolution of our project: Multipilot 2.0 ST.

Stay tuned :

This is the Official thread : http://www.virtualrobotix.com/forum/topics/multipilot-20-ap32-building

The characteristics of Multipilot 2.0 are:

• Hardware:

New Update.

We' add the support of Radio reciver, gyro and acc sensor that using SPI bus. EEPROM .

We're ready to fly. We need some debug on i2c bus and start to do preflight check.

In the picture you can see my first proto.

well done!!!

[Yadgarov Timur]

my greetings, i look with great interest to project

[Roberto Navoni]

I have the date of first Multipilot 2.0 pcb stock . They arrive at my farm the 26 /01/2011 . I'm very excite ... :)

I

[Roberto Navoni]

In this day I'm working on i2c and spi bus , I'm interconnecting IG3200 , BMP085 . Now I'm wokring on adc that is on Oilpan. When I have some time available i send some video of my result.

Hi Federico,

i cannot reply to your questions now :) Will be present in first week of next month. That week i hope to presente the board ,too with his accessories.

Regards

Roberto

 

[Federico Boldori]

Any information about the price range? :)

[Roberto Navoni]

Then i start to check some library feauture after libperf i test AP32_RC the new name of APM_RC for Multipilot 2.0 - Ardupilot32 .

I upgrade the library , I rewrite all the function for PPM rx_reciver and PPM output.

The library work fine . This is second library that i checked after libperf a library for performances mesaurment.

This is the video.

Thanks to Sandro for this beautifull Render :)

 

An example of using OilPan on Multipilot 2.0 / Ardupilot32 . A Perfect Arducopter Pro Update.
