2.3 error in GPS.cpp (serialGpsPrint) Can't init MTK

[vtpete]

When trying to compile the 2.3 MultiWii code, you have the options of defining: (#define INIT_MTK_GPS)
I'd like to do this in order to use the BAUD of 57600 rather than the default of 115200.

But, there is a compile time error in the code that seems to be well known. But, I can't find a solution on the 'net.
Some people say to go back to Arduino 1.0.5, but it doesn't have support for my MultiWii Pro board.

The error is below. Before I start to dig into the code, is there a known solution?

[QuadBow]

void SerialGpsPrint(prog_char* str) {

The error message you provided differ a bit from the original code shown below:

Code: Select all

void SerialGpsPrint(const char PROGMEM * str) {

Are you shure that you got a clean MW 2.3 distribution?

Wow, thanks, QuadBow. I was *so sure* that I had been working on a fresh copy of 2.3. But, after your post, I downloaded a fresh copy and just as you say, it's fine. Hey, I really appreciate you spending your time to help me out! And, I apologize for not checking that myself.

I *believe* that what I did was to start with the Hobby King website. I had copied some of the code that people had posted with "WORKING" on it. At the time, I honestly didn't even know that MultiWii should be downloaded from the code.google site.

Thanks again!
