Re: Access to tick from another source file.

Thanks. Can you show an example about how log variable can be used to transfer data between tasks? Thanks a lot!

Access to tick from another source file.

Hello, I am trying to access live tick value from another source file (connected with a task priority 2). So far, I have wrote the following: in stabilier.c file: uint32_t tick; uint32_t *pTickPTR = &tick; in other source file (lets assume filename: cf.c) extern uint32_t *pTickPTR; uint32_t tick; wh...

Re: Problems Kalman filter computation copy

No, I have not added any physical hw. It is in software. And how would you verify your development? Do you write your code in increments and flash it in hardware? Or is there some other way? Flashing into hardware multiple times should be inconvenient and we also need to see if the timing dependency...

Re: Nonparametric machine learning model written in CF2.1 firmware.

Thank you for your reply. However, I am also looking for implementation in C. Is there anybody who know of any such implementation? Thanks.

On a different note, I think it possible to have a cpp file as extern which would implement a regression model. Is there any work which does this?

Problems Kalman filter computation copy

Hello, My platform: CF2.1. I am trying to develop a dock which will essentially perform the EKF computation, but not on the original CF2.1 but on model. I essentially made a copy of the EKF codes (available from kalman_core.c). After doing this and defining the new code essentially a new deck, I am ...

Nonparametric machine learning model written in CF2.1 firmware.

Hello,
Is there any nonparametric machine learning model written in CF2.1 firmware? I am specifically looking for a nonparametric machine learning model for regression operation. It can be decision tree, gaussian process regression anything. Thanks a lot in advance.

Assert failed after watchdog timeout.

Hello, I have CF2.1 with lighthouse deck and flow deck. I added one custom deck (written in software) which is supposed to copy the EKF filter operation for my research. The code is compiling fine in computer with the makefile; however, I have following as the output when it is flashed in the cf2.1:...

Re: VL53L0X stand-alone and forcing drivers

Hello,

I got to make it work by the following code:

Code: Select all

CFLAGS += -DDECK_FORCE=deck1:deck2
Please note, the following does not work:

Code: Select all

CFLAGS += -DDECK_FORCE=deck1 : deck2
It is probably better to adjust code to take care of whitespace.

Query about mathematical model of CF2.1

Hello,

I would like to have an implementation of the mathematical model of the CF2.1. I know the model dynamics of a regular quadcopter but I do not know the value of parameters of the CF2.1 system. Does bitcraze or anybody have this already? How can I get the information about these parameters?
