Code and dev environment

[paul_l_curtis]

As Steve Jobs would say, "Just one more thing...."

Although I write CrossStudio, CrossWorks libraries, and so on, I would also say that I like developing my own code too. I suspect none of you are aware that I coded all the software in SolderCore project:

http://www.soldercore.com (Apparently I'm allowed to insert links now!)

To that end, as well as the SolderCore main board, we were very early in the queue for the MPU-6050:

http://soldercore.com/products/sensecore/corempu/

And then, I wrote an attitude and heading reference system and endowed CoreBASIC with quaternions:

http://soldercore.com/manual/corebasic_ahrs_driver.htm

That driver will fuse /any/ accelerometer, gyro, and magnetometer into an AHRS. The CoreMPU has all that, and then I demonstrated the sensor fusion by doing some 3D stuff all on the SolderCore's Cortex-M3:

This doesn't use the MPU-6050's DMP to do sensor fusion, it's all done by the Cortex-M3. And the 3D calculations. And the drawing.

The next thing to do is get the quad off the ground using my own software. I just love writing software...

So, I do have a common interest which is how I sort of stumbled around here.

Suppose you had a fairly large piece of code that you wanted to map out like AQ.
How would you go about it? Would you stick with grep or are there special tools out there that could be used perhaps in combination with crossworks?

Wow, Paul!

Amazing stuff you're working on. Welcome to the club.
You know ... getting quads off the ground is our domain.

If we can do something for you - just ask for it.

Hi,

following the instructions in "Developing your own code : a short introduction" to compile the latest revision I get the error:
bad value (cortex-m4) for -mcpu= switch

What do I have to do, how to continue?

Edit: OK, solved, for Cortex-M4 support at least crossworks 2.1 release is necessary.

Thanks for pointing that out! I've been neglecting the Makefile here

Here's an updated version for latest firmware. New option to set hardware version, auto-increments the build number in buildnum.h (can be disabled), automatic bin file naming based on firmware and board version, and a few other options & changes.

LMK if any issues.

@Max:
I´m trying to compile with the makefile in trunk r106. I have the three folders together (mavlink, onboard, STM32). I´ve found two problems:

1.- I can´t find the file "STM32f4.ld", that should be with STM32 folder from CW at location (in my win7):
C:\Users\AFD\AppData\Local\Rowley Associates Limited\CrossWorks for ARM\packages\targets

2.- doing a "make" I found following error (se image attached)
File "1wire.c" I guess is in the right place (under "onboard")

Any idea?
thanks

Hi Angel,

You don't have the .ld and .s files in the STM32 folder? I thought I got it from the d-load on the German forum... oh I see that file's not up anymore. The contents of the STM32/include I think come from STM (I have some with my discovery board download), but the .ld and .s I think are from Rowley (although I can't find them on my computer in any CW folders). I attached a copy of the original file from the other forum here (with the STM32 folder)... hope it's OK.

The compile error I think means it can't create the Release/obj/ folder (check if that exists), or perhaps it can't find the source folder at all for some reason. 1wire.c is simply the first file it tries to build.

Let me know if you still have issues...

Hi Max:
thx for your help. Using your files now. I get the following:

"Fatal error: stm32f4xx.h: no such file or directory"

I see in the makefile that the includes path is correct (I think)
INCLUDES = -I. -I./STM32/include etc...

Attached are the files I´m using. I have a CW folder copied under C:\
