Re: use ledring12.c file
I solved it after reading your article :D I solved the problem, but I still have questions. Each timer and channel is assigned to each dma stream and dma channel, which I understand is all independent. Even if the timers are the same, if the channels are different, I think they are assigned to diffe...

Re: use ledring12.c file
A new question occurred while using this to continue writing code. We are experimenting with replacing the existing pb5 port with pb8. Tim3 and Tim4 have not been further modified for the period because they have confirmed that they have the same performance on the datasheet. And I changed the exist...

Re: use ledring12.c file
After I posted this article, I found a very simple way to do many experiments. The function in the ws2812.c file was used without the code from the ledring deck. And in the schema of the ledring deck, the power part is connected to the vcom, and I connected it to the vcc. I don't know why, but the v...

Re: use ledring12.c file
I looked through the files you taught me. But the file was a simple led on-off file. The module I want to do is as shown in the following picture and is the same module as the leadring deck on your homepage. 11.GIF aa1.GIF The code we looked at to implement this is ledring12.c (crazyflie-firmware/sr...

use ledring12.c file
I want to use the ws2812 led module. I have already confirmed that the related functions are defined in the file called ledring12. it is manipulated through Python files. However, I would like to control the led by adding a new test without purchasing the ledring deck. I'd like to know how to implem...

Re: Bolt pin N11,N12
So when we manipulate this randomly, doesn't nrf have a problem?
We are currently connecting the bolt with the client by wireless radio and using 3 drones and p2p communication.
Is there a problem if we randomly connect lead to pin and give pwm signal?

Bolt pin N11,N12
I'm developing a drone using a bolt. In addition, I would like to use another pin to combine LEDs. But I already use another deck, so I have few extra pins. After looking at the available pins, we found that pins 6 and 7 on the right-hand side of the bolt are available. However, this pin reads N11, ...

avoid obstacles
While studying anti-collision algorithms for clusters, I found a file called oa.c inside the firmware. I saw the following post. https://www.bitcraze.io/2017/09/new-prototype-obstacle-avoidanceslam-deck/ After that, we checked to see if the additional deck was released, but we can't guess by name al...

Re: Spi sensor connect problem
We've never used the pin before, but we don't have to connect to do what we want to do now. At first, we were not aware of the unused pins, but now we suspect that there is a code for the pins to operate according to the length of the spi communication line. At first, we didn't recognize the unused ...

Re: Spi sensor connect problem
Recognizing performance anomalies based on the length of the line, we have examined the values through various experiments, but there is no problem, so we don't need to change the code further. And all problems were solved when pin io_2 was removed, and now both decks of lps and flow_deck are functi...
