New product: I2C splitter

This board ($7) just does what it says: allows you to connect four I2C sensors to APM via the I2C port. You can daisy-chain them if you need even more ;-)

Paparazzi I2C programming

Good day everyone,

I am working on a uav project at university. We want to integrate ultra sonic sensors with the paparazzi to use for auto takeoff and landing. We want to do this by using the I2C port. Does enyone know how one would adapt the source kode of the paparazzi in order to do this?

Thank you.

Sharp Distance Sensors with I2C

For my own rover, Data Bus, I've been working on a board that converts Sharp range sensors to I2C.

I ran out of analog ports and had to prototype an I2C solution for my obstacle detection. I have this problem on all my robots. Pokey has too few analog ports. And I want to run a few of these on my RPi tele-rover.

They'll work with any Sharp…

Servo Conversion - I2C Control





In various groups and blogs I peruse on here, there's been talk about I2C control of servos (as opposed to standard PWM). This certainly solves several problems, as it allows one I/O port (I2C) to service over a hundred servos with ease. With some built-in intelligence, the servo itself can… Continue

Mikrokopter BL-Ctrl i2c ESC support now in ArduCopter with Pixhawk/PX4

Mikrokopter UAV are very common in Germany. They use their own Brushless ESCs, controlled with i2c by their own Flightcontrol.



From now on, it is easy possible, to convert a Mikrokopter UAV into a fully featured ArduCopter with a Pixhawk or PX4 only by replacing the FlightControl&NaviControl.…

brushless motor speed controller connection in series on the bus through

two data lines (one for the clock SCL, one for data SDA), and send the

control signals to brushless… Continue

Flytron HMC5883L Triple Axis Magnetometer Breakout

HMC5883L is a 3-axis digital compass from Honeywell. Communication with the HMC5883L is simple and all done through an I2C interface. There is no on-board regulator, so a regulated voltage of 2.16-3.6VDC should be supplied.



This breadboard-friendly board breaks out pins  to a 4-pin 0.1" pitch header. We've also put two 10k pull-up resistors on the I2C…

I2C is delicate, I too see

My first attempt at communications was going to be I2C, with the ArduIMU as a writing master, and the Nano as a reading slave. I had hoped that the 5V nano would be OK with the 3.3V magnetometer, but COMMs were never achieved, and it seems to have damaged the mag.
So, back to serial, while I wait for FedEx to bring my early xmas gift.…

2nd Arduino adds 2-way Com with Ground

I wanted two way communication with my aircraft, but when the GPS is running, the Arduino board only has 1 side of its single serial port available, so I added another Arduino Mini to provide 2-way communication between my ground station and the aircraft.



The additional board consists of a 5 volt Arduino Mini Pro, with a ATMega 328 chip running at 16 mHz, and a Spark Fun 5 volt carrier board for the XBee. That's it. I had to move my Gyro to this new board, cause I used I2c to link… Continue

OpenLRS + wii motion plus

Hi there,

I know openLRS was slowest opensource project ever and i didnt release it since 5 months. But i will do that in 24 hours.

Today i tested the I2C functions for direct stabilization applications. OpenLRS receiver including serial and I2C ports for GPS and Sensors. Add a gyro / acc / magnetometer and you have an multicopter controller (or autopilot). you dont need an external receiver / autopilot or extra cabling between rc equipments and telemetry coming internally too… Continue

In development...

I have not posted up anything in a month so thought I should give an overview of what I've designed. Unfortunately I have hit a LARGE snag in that BatchPCB is basically broken for international orders as no shipping options appear and so you cannot buy anything (its been like this since January). 5 months of waiting to produce these (no international shipping) and I'm pretty…
