For your purposes, it is crazyflie-firmware.

mannaris wrote:2. can I use the driver from anasios for the crazyflie2 and my sensor(analog)?

I can't answer this, hopefully someone else can...

mannaris wrote:3. I dont find the place where I have to put the driver. The wiki says : "To compile the driver, place it in deck/drivers/src/ and add it to the Makefile"
But im not able to find these folders. i dont know what you mean with "the master branch".

Since you're using the VM from Bitcraze, you ought to be able to double-click the "Update all projects" file on the Desktop to update the firmware checkout on disk, thereby getting the folders Arnaud mentioned (you are using the GUI, yes? If not, run "startx" at the command prompt). Look inside the "projects/crazyflie-firmware" folder (on the Desktop) and you should see the "deck" folder. If it isn't there, open a terminal and run the following:

Code: Select all

cd ~/projects/crazyflie-firmware
git checkout master

Then look for the "deck" folder inside crazyflie-firmware again. It should be there.
-or-

If you download the zip file from GitHub, it contains the master branch. If you want to clone the repository yourself, you will get the master branch by default. If you want to use Git (ie. to clone, update, switch branches, or otherwise), I will point you to the official Git documentation so you can read up there and learn how to use it.

Hi,

2.
The code I posted in this answer would work for analog sensors: viewtopic.php?f=6&t=1770#p9068

3.
We just published a small howto to help getting started to add code to the Crazyflie: https://wiki.bitcraze.io/doc:crazyflie: ... deck:howto, as Chad answered you should be on the master branch.

So this is my driver:

Code: Select all

#include "deck.h"

#include "log.h"

#include "FreeRTOS.h"
#include "timers.h"

static xTimerHandle timer;
static float range1;



// This function will be called by the FreeRTOS timer every 100ms
void SensorValue(xTimerHandle timer)
{
   range1=analogRead(DECK_GPIO_RX1); // Reading the value of the sensor 1

}

void mySensorInit(DeckInfo *info)
{
  pinMode(DECK_GPIO_RX1,INPUT); // Set my sensor 1 as an input

  // Create and start the update timer with a period of 100ms
  timer = xTimerCreate("irsensorTmr", M2T(100), pdTRUE, NULL, SensorValue);
  xTimerStart(timer, 100);
}

static const DeckDriver mySensor_driver = {
  .name = "myIrSensors",

  .usedGpio = DECK_USING_RX1
  .init = mySensorInit,
};

DECK_DRIVER(mySensor_driver);

// Add sensor reading as log variables
LOG_GROUP_START(myIrSensors)
LOG_ADD(LOG_FLOAT, range1, &range1)
LOG_GROUP_STOP(myIrSensors)

and here i ve add this to the makefile:

Code: Select all

# Decks
PROJ_OBJ_CF2 += bigquad.o
PROJ_OBJ_CF2 += exptest.o
PROJ_OBJ_CF2 += ledring12.o
PROJ_OBJ_CF2 += buzzdeck.o
PROJ_OBJ_CF2 += gtgps.o
PROJ_OBJ_CF2 += infrarot.o

but the command "crazyflie-firmware$ make" in the Shell only leads to "crazyflie-firmware$: command not found"

Where is my fault?
and is the enabling of the driver important..?

At the command prompt, are you actually typing "crazyflie-firmware$ make"?

You should change into the directory "crazyflie-firmware" and only type "make all" at the prompt. As in:

Code: Select all

cd ~/projects/crazyflie-firmware
make all

Then i got this:

Code: Select all

bitcraze@bitcraze-vm:~/projects/crazyflie-firmware$ make all
Makefile:347: tools/make/targets.mk: No such file or directory
make: *** No rule to make target 'tools/make/targets.mk'.  Stop.

It sounds to me like either your checkout of the repository is broken or your Makefile broken. First do this... Type the following in the terminal:

Code: Select all

ls ~/projects/crazyflie-firmware/tools

The output should look the same as this:

Code: Select all

build   eclipse make    trace

If there's an error and you don't have a "tools" directory, refer to this post in this thread.
If you do have a "tools" directory and your output is the same as above, check line #347 of the Makefile:

Code: Select all

nano +347 ~/projects/crazyflie-firmware/Makefile

The output should show the following above the cursor:

Code: Select all

include tools/make/targets.mk

If it doesn't, you need to fix your Makefile.

Let us know how it goes.

typing

Code: Select all

ls ~/projects/crazyflie-firmware/tools

leads to:

Code: Select all

bitcraze@bitcraze-vm:~$ ls ~/projects/crazyflie-firmware/tools
ls: cannot access /home/bitcraze/projects/crazyflie-firmware/tools: No such file or directory

I am in the master branch and i have update all projects.

Well, that indeed is the problem then. If you'll take a look at the file hierarchy here on Github, you'll see the the repository does have a tools directory. I'm left wondering two things:

1) Are the files and folders inside your crazyflie-firmware directory the same as what's shown on Github at the above link?
2) Could you have accidentally deleted directories from your repository clone?

If you run the following command in your terminal (while inside the crazyflie-firmware directory, of course) what does the output contain?

Code: Select all

git status

Posted: **Tue Dec 22, 2015 5:47 pm**

Then I got this:

Code: Select all

fatal: Not a git repository (or any of the parent directories): .git

Hi mannaris, this is getting a bit tedious. It's obvious your git clone is destroyed somehow or you are having trouble using the VM or the command line. Let me ask you a few questions:

1) Are you inside the crazyflie-firmware directory when you run the git status command. i.e.:

Code: Select all

cd ~/projects/crazyflie-firmware
git status

2) Are you sure this is a cloned repository or is it a downloaded zip file from Github? The latter doesn't have git repo information.
3) Have you viewed the documentation on using git? It would go a long way for you to help yourself if you understood the tools you are working with.
4) Are you actually using the Bitcraze 0.6 VM? Unless you have significantly changed things, the VM is setup correctly to start with. You shouldn't be having the issues you are reporting if you're using the 0.6 VM

Let me suggest here that you start from scratch instead of using my time to hold your hand through each one of these basic problems. Download the VM again, run the update script on the desktop, then add your driver software and see what happens. You'll likely have better luck and be more successful if you have a clean starting point.
