Compile errors: FreeIMU_serial_ARM_9250_3115A2.ino

[nandomtl]

I am trying to compile the module in the subject line, but am getting a pile of error msgs. Probably a rookie mistake, but I can't figure what's the glitch... Below are the first few msgs - to make it more readable, I removed the prefix in all but the first line.

Hi - thanks for trying the library. Lets see if I can help.

1. Did you remember to change the FreeIMU.h file to set the configuration for your board. The sketch that you selected is for the MPU-9250 and the MPL3115 barometer. You will need to uncomment the line for define Mario and comment any other board define that is currently defined. Check out the wiki it should explain a little more on how to do this.
2. Some of the errors look like you are the Arduino 1.0.6 lDE. You will need to use the Arduino 1.5.7 or greater IDE.

If this does not work let me know what IMU you are using and Arduino board. I have been using primarily the Mega2560 and the Teensy 3.1. If you are using a Uno it probably won't fit.

[nandomtl]

Hello

1 - Yes, I did that. I am using an invensense MPU9250, but I should not be using "FreeIMU_serial_ARM_9250_3115A2.ino", as I have no other sensors on the board. 2 - I installed 1.5.8 - still had some errors about missing files, but nothing I needed (such as L3G.h), so I commented them out and the compile ran. But: 3 - You are correct - the compiled code (most sketches) does not fit in the Uno.

I still am puzzled with the #include statement and the position of the libraries in the folder tree. In one particular case (FreeIMU_quaternion.ino), the compiler dies because: AK8963.h: No such file or directory

include "AK8963.h"

As you can see in my original post, the folder+file are there, and "preferences" points to /Users/username/Documents/Arduino/. Also, I can see the folder name under the menu sketch/import libraries >, along with a couple dozen other folder names that are part of this package (screen shot below).

If you know of a good reference about this subject, I would appreciate if you could share it. (Already been to http://arduino.cc/en/Guide/Libraries.)

PS: is there a document in this package that describes what the several modules purpose is? Sometimes the name tells everything one needs to know, but at times I can't figure it.

Thanks for you help

[mjs513]

Real simple fix here. Add the following line to the sketch (FreeIMU_quaternion.ino) along with the other includes:

include

It should now compile for you. Missed that adding that one. Unfortunately I don't know of any good reference for this issue. I learned from trial and error.

The sketch you should be using is: FreeIMU_serial_ARM_CPU.ino, this will give you everything you need from the 9250. Just remember to comment out all the board defines except for the GEN_9250.

I have not got around to create a list and explanation of all the examples. Like you said most were self explanatory.

Mike

[nandomtl]

Hello

Thanks for the quick reply Did you mean just #include with no parameters? The compiler does not like that... FreeIMU_quaternion.ino:4:9: error: #include expects "FILENAME" or

Cheers

Carlos

[mjs513]

Hi Carlos,

My mistake - suppose to be #include

Sorry about that.

Mike

[mjs513]

Interesting, just checked my post and it didn't do the include correctly. Lets try something different:

include < AK8963.h >

Leave out the spaces before and after AK8963.h if the compiler complains.

Mike

[nandomtl]

Mike, I did the tests - but...

include

produces: FreeIMU_quaternion_V2.ino:32:9: error: #include expects "FILENAME" or Error compiling.

...and

include < AK8963.h >

gives: FreeIMU_quaternion_V2.ino:4:22: fatal error: AK8963.h : No such file or directory (I also tried double quotes, no joy.) To make sure other files in the libraries folder were being picked up, I rename one of them (ADXL345.h), and the compiler complained about it. FreeIMU_quaternion_V2.ino:2:21: fatal error: ADXL345.h: No such file or directory So the compiler is looking at the right folder tree. Weird.

Carlos

[mjs513]

Carlos. This very strange. Have to think about this one. Did you ditch the spaces after < and before the closing >. So it reads #include

Also just do a double check that the only board you have selected is the

9250. Does this happen on the FreeIMU_SERIAL_ARM_CPU.ino sketch?

Hi, Mike My previous post somehow got truncated: the first test was without the spaces, and the compiler gives a syntax error (... expects "FILENAME" or ). The weird thing is that other "#include" statements do NOT have the spaces - see below a few lines pasted from the file.

The FreeIMU_SERIAL_ARM_CPU.ino compiles nicely but does not load, it is too big for the Uno. I bit less than 2 K bytes...

Hi Carlos

Well the configuration looks correct. Since the other sketch compiles then it is with the quaternion sketch. Did you try to compile without the spaces. If you didn't give it a try.

I have attached the sketch that compiles without issue for me. Let me know if you have a problem. Don’t use the one with matrix at the end – trying to convert quaternion to dcm. Still have to get the math right on that one J

Mike, your code compiled fine (after I had a couple of library issues fixed). But, to fix the library issues, I moved the source code a couple of levels higher (to /Users/carlossa/Documents/Arduino/FreeIMU_quaternion), so I was suspicious that the problem was the folder location. I then moved the original quaternion folder/source code to that position, and tried again. The same old problem was there... phew! But this time I decided to follow the compiler's suggestion:

---

In file included from FreeIMU_quaternion.ino:28:0: /Users/carlossa/Documents/Arduino/libraries/FreeIMU/FreeIMU.h:299:22: fatal error: AK8963.h: No such file or directory

include "AK8963.h"

                  ^

compilation terminated. Error compiling.

---

I added the statement #include "AK8963.h" to the file, and the compiler was happy! I do not know enough about C to understand the difference between including with <> and "", but this fixed the issue.

Thanks a lot for your help!

Just checked it out. Very nice. Becateful with using men's. Pretty susceptible to interference from large iron like table legs, temperature, etc. Will dig up some references for you and post them.

The instruments driven by the 9250 won't be critical - the plane is going to be VFR only. (Did you see the video?)

I'm an engineer too (electrical), but have spent all of my professional life in IT.

Just saw it. Had to view the link in desktop view to see and read everything.

Like the instrument panel. Struggled to get it working in processing.

By the way booked marked the page so I can follow.

Will read when more awake. By the way if you need to reach me you can email at FreeIMU@aol.com.

I have tested the code out on a uno, Mega, Teensy 3.1, Due, and even on the Intel board. Had problems with Intel reading multiple I2c devices and missing standard libraries. Haven't played with a pcduino, will have to give it a try one of these days.

Been working on the library updates for over a year. So yep, slow going but fun.

Good luck. Mike

The instruments driven by the 9250 won't be critical - the plane is going to be VFR only. (Did you see the video?)

I'm an engineer too (electrical), but have spent all of my professional life in IT.

Cheers

Carlos
