I can't figure out how to write the code in Assembler to get the desired result: sequentially light the LEDs clockwise with an interval of 0.5 seconds Assembler is not my strong point, I have a rough idea how to write this cide in C, but Assembler is a bit complicated for me. Maybe someone has some ideas what I should do. Thank you for any help
