W2812 led

[Lalbabu2001]

Hi , when I was using version 6.1.0 the led strip used to work fine, In version 6.1.1 is not working.

Hi, in FW 7.1 I have the problem with the W2812 LED strip, if I enable the LED strip in the configuration, save and restart, the option remains disabled. I also tried with the CLI command. Software serials are disabled. I looked at the guide you posted but I can't find anything that explains why there could be a possible conflict. The pin for strip is A8. Many thanks

Have you connected the LED to PA8 pin using 100 OHM? You also need to use external power supply. Do not use Board 5V. The board will burn.

Hi, yes I connected the resistor between pin PA8 and DIN, used an external power supply. I tested the LEDs with another micro and they work. I believe that the problem is when the "Multi-color RGB LED strip support" option is active, when saving and rebooting, it is no longer active. I connected the PA8 pin to the oscilloscope to see what the signal is like and it is always at 0, there are no pulses. Thanks

If the option in the image is active, it means there is support.

If the option in the image is not active, you need to turn on support with the CLI command. To do this, first run the CLI command "feature" and see the screen below. Is the LED_STRIP feature available on the screen? If so, it is active.

If the LED_STRIP feature is not on the screen, then use the command below. CLI: Enable the LED_STRIP feature via the cli:

feature LED_STRIP

Run the CLI command "feature" again and see if the LED_STRIP feature is turned on on the screen. Check.

Hi, I did the check you asked for, you can see it in the image. But when I save and reboot, the setting is disabled. I don't know, it's very strange, everything works except the LED strip.

There is a conflict somewhere. LED STRIP How did you connect it? If you have a video or photo, can you share it?

[suchigno]

The LED strip is connected to the PA8 pin with a 300 ohm resistor. The photo shows the breadboard with connections, the connected sensors are: MPU6500 hmc5883 Buzzers Led Strip Receiver via SBUS and inverter (as per the connection shown by you). I also tried with PPM signal. This all works.

I also post the port configuration, if there is a conflict, and the serial software are disabled I don't know what it could be, because I only use two sensors (SPI and i2c) and I don't use any serial modules such as GPS, telemetry etc. However, even without the LED strip, it's still a nice project, I can even do without it and I use a LED with the buzzer pin to alert me to errors.

More than anything else I have an idea, but maybe I'll open another issue on this. Would it be possible to connect a Bluetooth module, such as the HC-06, or jdy-08, to connect the board via Bluetooth, for example, to a phone and use the APP to calibrate it, change the parameters, without having to connect it to the laptop?

[rizacelik]

There's a lot of wiring involved. To test LED STRIP, just connect the MPU9250 module to the board. If the LED STRIP does not activate again, there is another problem.

I don't know how to use a Bluetooth module like HC-06 or jdy-08. I've never seen such a connection option.

Please read source.

Thanks for your help, but the result doesn't change. I removed all connections and connected only another IMU, (the MPU6050 i2C), and left the buzzer. Unfortunately the strip configuration remains disabled after the reboot. For bluetooth I decided not to implement it, I tried the OTG cable with my phone and with the speddybee APP and it works well. So for the first few flights I will use the phone to see if everything works well.

[rizacelik]

If LED STRIP is not working, there is nothing to do. Ignore this for now.

When you make the Bluetooth connection, write here how you did it. Let others benefit too. I can't keep up with everything.

[suchigno]

Sure, my idea was to use a cheap bluetooth module (JDY-08) which should be compatible with the speedybee APP. If everything works, post here how to do it. Thanks

i'm also facing same problem when i turned on led strip setup it automatically disabled and also cli is not working and i add 330ohm resistor still this problem facing
