OK, found some useful tools for making the bitmaps, but my display renders them as properly sized/scaled gibberish. Yet my hand-constructed icons are functional - go figure. Working with what I had, I made some simple line-art icons which currently take a number of parameters - linecolor, fillcolor, transparencycolor.
Going to add alarmcolor as a variant of linecolor on a trigger value.
Entire display system is Themeable!
though you will want to define additional colors for your palette.
- Code: Select all
// note to self: make the themes a 2D array, then select theme based on timer or event.
//int myTheme [] = {CYAN,GREEN,OLIVE,YELLOW,OLIVE}; // Greens - kinda bright
//int myTheme [] = {CYAN,OLIVE,GREENdk,YELLOW,GREENdk}; // Darker Green
int myTheme [] = {CYAN,REDdk2,REDdk,YELLOW,REDdk}; // a nice red theme for nighttime
//int myTheme [] = {CYAN,BLUE,BLUEdk1,YELLOW,BLUEGREYdk}; // Da Blues
Sample final code, which I've called RoboShow and include in whole below, renders 12 visual sensor data points in ~1.3 sec on 1.8"tft. Code can likely be optimized. There are dependency libs, but nothing oddball or extremely heavy. SPI, Wire, Adafruit_GFX/ST7735/BMP085, NewPing
PIR (x2)
PING (x2)
Sonar
BMP-temp // selectable F/C display
BMP-alt // selectable f/m display
BMP-bar
ACCEL-x
ACCEL-y
ACCEL-z
Battery // icon/placeholder
So, anyway.
I apologize to everyone who unknowingly contributed, for caught up in the moment as I was I was literally copy/pasting code not expecting it to really work. There is so much of the community in RoboShow, that I believe the code should be set free to mix and mingle with other code-lings as it sees fit.
Do as thou will, harm none.
