Multiwii pro board layout

[MarcGr]

Hi all,

I'm trying to program with AVR-C on the atmega 2560 on the multiwii pro, but I'm having trouble communicating through USART. (Declared strings as

Code: Select all

char string[] = "hello world!\n\r";

are not put in SRAM at startup)
The problem is described on http://www.avrfreaks.net/comment/1523196.

Anyhow, I'd like to know the exact layout of the board for debugging. I'm having much trouble to find a schematic of the multiwii pro.
If there are multiple versions, I do not know which one I have, or how I could identify the version of mine.

Thanks in advance

Marc

I'm having much trouble to find a schematic of the multiwii pro.

I know a red board from Hobbyking called Multiwii Pro and a blue board from Hobbyking called Multiwii Pro. So, your dealer (=Hobbyking?) should be able to provide the related information.

I bought it from hobbyking indeed. Their site referred to multiwii.com for more information.
I couldnt find much relevant information, so I asked you guys. I will contact hobbyking

Thanks

Contacting HK will not help much since customer support is not their focal point. But, there are some customer uploads available under the "file" section at the bottom of http://hobbyking.com/hobbyking/store/__31138__Multiwii_and_Megapirate_AIO_Flight_Controller_w_FTDI_ATmega_2560_V2_0.html. There you can find one file that might be interesting http://www.hobbyking.com/hobbyking/store/uploads/375568553X945087X44.jpg
