AVR for Aero Ace motor-speed control

[wolfv]

Aero Ace (AA) is a great little airplane, but it lacks low-power control. The goal of this project is to modify the AA transmitter to eneble a larger range of motor control for:
* low power (so airplane will not climb at lowest power setting)
* zero turn (one motor off, other motor on low power)
* barrel roll or spin (one motor off, other motor on max power)
The plan is to replace the AA Tx stock processor (EM55100) with a PIC or AVR processor.
An AA Tx schematic is located at http://www.wattflyer.com/forums/showpost.php?p=38634&postcount=165
I think using a AVR Attiny2313 processor would be best http://www.atmel.com/dyn/products/product_card.asp?part_id=3229

I have already written and tested the attached program on my PC. 80 lines of code need to be ported from this program to an AVR processor. This could be a fun project for someone that already knows AVR and has the hardware to make it happen. I will answer any questions about the program.

I am a software guy but I do not posses the tools or knowledge to program AVR. I have carried this project as far as I can and would like to see an AVR person take it from here. I had fun writing the program, and I think it would be fun for an AVR person to complete the final product.

After testing, you or someone else could sell a batch of programmed processors on eBay or to an online retailer. That way many AA mods could benefit.

For those not familiar with the Aero Ace, there is a thread with a similar topic on http://www.rcgroups.com/forums/showthread.php?t=470028

Is anyone interested in porting this program to AVR?

Thank you,
wolfv.

wolfv,

I am pretty sure this has already been done.

If it hasnt - I can help you out with Atmel programming.

andrewm1973,
I wish. I searched the forum for “AA AVR” and “Aero Ace AVR”. Found 15 results, none used AVR to modify speeds on an Aero-Ace transmitter. Thank you for your offer of help, but I don’t have the time to learn AVR this year.

quax,
Your page inspired me to start this project! Your page was very informative. I am new to Aero Ace and electronics and your page showed me the way. Thank you for publishing your knowledge. Mine is basically the same idea but uses the Aero-Ace transmitter instead of the X-UFO radio.
