Serial.print (F("unsigned char"));

AWOL, even more funny considering the profile picture
You can't. You can't even upload that to the rp2040. You must have the setup() and loop() functions defined, as a minimum.
I used Serial.print(car);
but I have this error:
no matching function for call to 'print(unsigned char*&)'
Cast it char (assuming it is null terminated)
Yes, of course, this is not my problem
Yes, it is. The code you posted will not compile, so it will not upload.
Imagine if your car is broken and will not start. So you remove one of the wing mirrors, take that with you as you take the bus to the garage and hand the wing mirror to the mechanic. Can the mechanic diagnose why your car won't start by examining the wing mirror?
