Re: only two tags range at the same time with TDMA

Hi Justin, Nice that TDMA is working outside of our lab :-). The variable DWM1000_TDMA_SLOTS_BITS defines the number of bit allocated for the slot number. To have 3 tags you need to set it to 2 (then there is space for 4 tags, 0 to 3). The line in config.mk will then look like that (one for each tag...

Re: Problem after uploading the firmware

Can you switch off with the button? It could actually be a case where the button is not working properly.

Re: Problem after uploading the firmware

Hi,

It is possible that the flashing failed, you can always restart the bootloader and try again (it is not possible to erase the radio bootloader while bootloading, this makes it safe).

You can restart the bootloader by pressing long the power button until M2 blinks and re-frash again.

Re: Unable to locate the package ros-kinetic-joy

I have never installed it that way so I am not sure how it works, they seems to use a special script to install dependencies? If you are not using the normal ros distro you will have to find out how to install the joy module. Please update us if you manage, running on raspi is interesting. The secti...

Re: Unable to locate the package ros-kinetic-joy

If you do now know it is certainly 32bit, also called armhf. ROS is not supported on jessie armhf: http://wiki.ros.org/ROS/Installation/ I am surprised you managed to install the rest of ros. You need Ubuntu xenial to be able to run on Raspberry pi as far as I understand (which is unfortunate since ...

Re: Unable to locate the package ros-kinetic-joy

Hi,

This is strange because the armhf version of this package seems to exist: http://packages.ros.org/ros/ubuntu/pool ... netic-joy/

Are you running Ubuntu Xenial on your Raspberry pi?

Re: moving ave filter

Yes it is. It was made by Wolfgang, he got better results with the lms than with the particle filer. Unfortunately I never manage to get it to run properly in my setup.

Re: Compiling Crazyflie firmware in keil - linker section

This has nothing to do with Malloc, structures are put in a custom sections and these variable will indicate the start and end address of the section. You will have to look at the documentation of the keill linker to see how to implement similar functionality. The reason I was suspecting that you ar...
