i am working on auto piloting of an aircraft first i have to control the pitch. for that i have to select a micro controller which can take data from sensor and manipulate the data, i have to interface these things with micro controller.
1) external memory
2) sensor (using usart)
3) generate PWM for servo

what micro controller you suggest ??? plzz give some reason why i have to use that micro controller????
thanxx:cool:
 

Hi,

You might be better looking at the diy sites that specialize in such things; just google 'diy autopilot rc plane' for many such links.
 

It would wise to include a method of overrideing the autopilot from the RX unit, this would allow you to take control of the unit.

I am not sure of the regulations in your country regarding these kind of devices, but in the UK they are under the regulation of the CAA and air navigation order.
 

plz first help me to chose micro controller for above given specificationn
 

There are numerous MCUs which would meet your requirements, PIC, AVR, MSP430, etc. However, many of the IMU Sensor Boards that I have come across utilize an AVR. Therefore, the abundance of code examples for this specific application maybe skewed in AVRs favor.

The most important factor, after the ability of MCU to meet the applications requirements, in making your choice is your comfort level in coding and developing for it.

I suggest, before making your choice, you Google for similar projects and see what would be easiest for you to adapt to your project's requirements.

ya i google i select pic16f877a for that now any one can help me interfacing sensor i am using vn100 development board. can any one provide some kind of example code in witch vn100 is interface to the micro controller so that i have some idea how to interface that. i am also studying its documentation but it hard to understand example with micro controller is not given. thnxxx for response.
 

Is this the dev board you have?



If so, I have already downloaded the datasheet and user manual. It uses an Serial Peripheral Interface (SPI), so you shouldn't have too much trouble writing the routines with the provided libraries.

Have you already purchased the PIC16F877A? If not you may want to consider the PIC16F887 it is a newer model with an ECCP which might come in handy.

I can steer you to some example code for implementing the SPI interface and possibly a tutorial.

Actually, let me research the requirements of the provided library. There maybe a better choice of PIC.
 

i already buy pic16f877a..

now i want some example code for that with pic i cant find on net plz send me link or that code

i cant under stand the coding from the manual. its difficult.
