The examples (https://github.com/ArduPilot/pymavlink/tree/master/generator/Ada/examples) are implemented using Serial communication. When I tried to update one of the examples with UDP protocol, Mav_Conn.Parse_Byte() is not returning true (But I'm receiving the data). I'm not sure, what I've done wrong, Can someone help me with this?

Also, adding the code for your reference, Thank you:

I'm having issues connecting the WS2812B with Raspberry Pi Pico. I'm trying to execute the example program https://github.com/JeremyGrosser/pico_examples/blob/master/ws2812_demo/src/main.adb

But after loading this executable only the inbuilt LED is blinking. I do not have any logic analyzers to check the output, but the data output is in the range of 1.7v to 2v. So I've connected a 3.3v to 5v level shifter but still no response in the strip. But the strip is working fine with micro-python.

Has anyone tried using the WS2812B strip with pico? I'm currently not sure what I've missed.
