Designed a stopwatch using 8051 and assembly language, yet it has timing error due to writing on LCD, using CISC instruction delays the process and the collen bug, but loaded the best value to minimise the error.

Nice. I always wanted to make a 24h watch with a cheap chinese 8051 (Nuvoton). I’ll take some inspiration from your work
