Given the following function:
If I execute setColor("R:0,G:0,B:255,");
I'm expecting the red
, grn
, blu
values to be:
0 0 255
except I'm getting 0 0 0
It's working fine for R:255,G:0,B:0,
or R:0,G:255,B:0,
though.
int setColor(String command) {
//Parse the incoming command string
//Example command R:123,G:100,B:50,
//RGB values should be between 0 to 255
int red = getColorValue(command, "R:", "G");
int grn = getColorValue(command, "G:", "B");
int blu = getColorValue(command, "B:", ",");
// Set the color of the entire Neopixel ring.
uint16_t i;
for (i = 0; i < strip.numPixels(); i++) {
strip.setPixelColor(i, strip.Color(red, grn, blu));
}
strip.show();
return 1;
}
int getColorValue(String command, String first, String second) {
int rgbValue;
String val = command.substring(command.indexOf(first)+2, command.indexOf(second));
val.trim();
rgbValue = val.toInt();
return rgbValue;
}
I ended up just modifying my code:
int setColor(String command) {
int commaIndex = command.indexOf(',');
int secondCommaIndex = command.indexOf(',', commaIndex+1);
int lastCommaIndex = command.lastIndexOf(',');
String red = command.substring(0, commaIndex);
String grn = command.substring(commaIndex+1, secondCommaIndex);
String blu = command.substring(lastCommaIndex+1);
// Set the color of the entire Neopixel ring.
uint16_t i;
for (i = 0; i < strip.numPixels(); i++) {
strip.setPixelColor(i, strip.Color(red.toInt(), grn.toInt(), blu.toInt()));
}
strip.show();
return 1;
}
I simply just do: 255,0,0
and it works a treat.
