2024-05-16 (F) Weekly Summary

I downloaded the VibeClock REV1 program, but initially, there was no light activity until I cleared a short between the signal and power, resulting in the first sixty LEDs lighting up in a pie-slice shape. I wrote a multidimensional array with the first locations separated by ring number. After debugging, my testing function turned on the lights one ring at a time while cycling through colors.

Rings changing colors

I needed a function that would return the address of any LED when I supplied a ring and position. The function also needed to respond to the position "-1" with the last light on the ring. I started with a purpose-built function that focused on the 60-light ring, responded to seconds, and then moved to the goal. There was some messy math, but I got it working.

Code for turning on LEDs in a continuous ring

I used yesterday's function, which translated a ring and position into the address of any LED. With this ability, I could calculate a line based on the time and number of lights in a ring. Unfortunately, the line was unsettlingly jagged. The effect may be less abrupt when there is a border between two colors.

A line traveling at one increment per second

I converted the line-drawing function into one that changed the clockface from one color to another. I tweaked a few settings to make it look nice, and I was delighted that it looked more purposeful than the squiggly line I had yesterday.

Filling the clock with red lights

I got the hour hand functioning, but it was a blue dot with a floating triangle unless the hour was divisible by three, in which case I could connect four LEDs in a row. I got the non-volatile memory working so I can set the time zone and retain that value after a power cycle.

One o'clock showing in blue (1:18 to be precise)

Sarah, Amanda, and I welcomed Chris from Home Brewed Comics to discuss his upcoming comic, C.R.I.T. and Thunderbolts*. The show peaked when Amanda pulled the loose story threads we missed or ignored.
