"I simply don't understand. Next year for sure, somebody will give us a link to
one another possible autopilot: 256 processors, 128GB RAM, 12GHZ speed. All in one chip.
Theoretically, one super autopilot like this will be able to work with…"

Hans Petter Grimstad commented on Sergiu's blog post Autopilot with XMEGA128A1 and ADXRS453 gyros"Did you get the MPL3115A2 to work?
I have always used SPI parts and have never written an I2C communication before.
If you want to share your code it would be great!
I also use Bascom for programming. everyone around me asks why i don't code in…"

Sergiu commented on Sergiu's blog post First flight Xmega AP and Hexa Configuration"@George P. - If you twist all cables (plus with minus,motor cables), lot of EMI will be canceled;however 2-3 deg error will be in compass when motors are spinning but can be removed in software.
@Crispin - Thank you."
Crispin commented on Sergiu's blog post First flight Xmega AP and Hexa Configuration"That looks neat. the 3DR ones look like they vomited thier intestines. I'm trying to make mine look neat :("
George P. commented on Sergiu's blog post First flight Xmega AP and Hexa Configuration"In general, it is recommenent to place the ESC's as close as possible to the motors.
Otherwise too much electric noise may radiated and interference with other sensitive electronics."

Do you have moreinfo on the AP board?"

So far I am one man show. So it takes longer time to finish one project than team working. On the other hand it have only my mistakes...For more info on two MCU's AP see my other post…"
Eugenijus Kostrubinas commented on Sergiu's blog post Autopilot with XMEGA128A1 and ADXRS453 gyros"Thank you. Sounds good.Have you a team for programming all stuff, or you it by yourself only? It is not as simple question as it look at a fist glance - it is the we will observe it flying. Have you a some deadline?Yours,Eugenijus"
Sergiu commented on Sergiu's blog post Autopilot with XMEGA128A1 and ADXRS453 gyros"Euginijus,
At the beginning I made Ap's with even 4 MCU's. All of them ATmega. One was doing R/C reading, another GPS and compass,etc. I did a big step forward when XMEGA came out. With it, I made my first AP with one MCU only. It was…"

I just got 3 pcs. ADXRS453 gyros from Analog Devices ( Farnell price was 100US$ for one piece.)
I added also one ADXRS610 in the picture to compare the size of the gyros. As you can see it can be connected vertical for pitch/roll or horizontal for yaw.This is from data…

This is my first blog here so just few words about me: I’m an electronic engineer, I'm from Romania and my hobby is obvious.
By more than one year now, I spent lot of time working with Atmel XMEGA family. My first autopilot with XMEGA 128A1 had external 16bit ADC (ADS8344) because at that time, internal 12bit ADC and DMA were still unclear to me. MPX pressure sensors for air speed and altitude, HMC5843 compass, ADXRS610 gyros and LIS344 accelerometer.…
