Stray error 302

WHat does error 302 mean and what is the way to fix it?

Code is attached

you need to open your code with another more capable text editor (showing invisible chars) and hunt for "weird" characters.. you have plenty of them...

find one - and do a find and replace with a space

I did the modification in the attached file, give it a try (I don't have the rest of your code so could not try to compile)

Ok, I have fixed the weird characters that you pointed out. However, there is still an error (stray '\302' in program) with the line "Adafruit_ST7735 tft = Adafruit_ST7735(cs, dc, mosi, sclk, rst);" highlighted.

How hard to understand is "Post your code" ?

Good - did you notice i had attached the fixed file in #1?

:slight_smile:

No, I didn't realize .... But just tested it and guess what ..... IT WORKS !!!!!

YOU ARE THE BEST !!!! THANK YOU !!!

if you don't mind, can you tell me what did you change?

Did the find and replace for the stray character represented with the dot

You could also have copied back as suggested from your properly formatted code here in the forum. That cleans it too
