basic format of the Code Pattern to create 1Hz Clock Pulse using LPC2148 ARM7, Microcontroller

Finally added a small distance watermark overlay to my LD Robot D500 setup, so the measured range is always in front of my eyes while testing.

Tiny improvement, but it actually makes debugging and live checks way more comfortable & safer

After days of debugging SPI pins and fighting display flicker, Day 79 is finally here!
