Is it wrong to feel good about posting code that works? :) -Glad to give my part when I can.Ĭode: Select all | TOGGLE FULL SIZE #include "TFTLCD.h"ĭuemilanove/Diecimila/UNO/etc ('168 and '328 chips) microcontoller:įor Mega's use pins 22 thru 29 (on the double header at the end) The wiring is the same as the 2.8" TFT tutorial found here: įorgot to mention, I did put the backlight on pin 10 for pwm control. I put a Youtube video of how it works for anyone wanting a preview before building. If you saturate the color by 10, you get B90063, and if you desaturate by 10, it is B91E72. A 20 lighter version of the original color is F6579C, and 7E003A is the 20 darker color. A complement of this color would be 0CB95C, and the grayscale version is 4A4A4A. Thanks ktownsend! I used one of the line from that, and it works now! :D I'll put the code below for anyone who wants to use it, it should work on Lady Ada's new touch shield, as it is based off of the TFT Paint sketch. The Hex color B90C69 is a dark color, and the websafe version is hex CC0066. Whereas in the RYB color system, a subtractive color system means the more you add, the more you get closer to white. RGB color system is an additive color system, which means the more you add, the more you get closer to white. Return shifted bits with alpha set to 0xFF RGB stands for Red, Green, and Blue, and these are the primary colors of light.

How to convert RGB values into the equivalent hexadecimal value Example of that like in this format 0x1906.
I have stored these values in three integers. Uint32_t red = bits & 0xF800 // 5 bits red In my C++ application, I have a png image's color in terms of Red, Green, Blue values. Uint32_t green = bits & 0x07E0 // 6 bits green Uint32_t blue = bits & 0x001F // 5 bits blue 18 October, 2013 Post navigation ← New Blog added at CMairsCreate! jQuery Mobile Video Training at Educator.Here is a C function that converts 8-bit R/G/B into RGB565:Ĭode: Select all | TOGGLE FULL SIZE Converts a 24-bit RGB color to an equivalent 16-bit RGB565 rĨ-bit Get 16-bit equivalent of 24-bit color The ability to use transparency is available in all browsers except Internet Explorer 8 or earlier and is considered a new CSS3 feature. The value of 1 eliminates the entire transparency showing the full color. The last decimal value determines the alpha transparency for the color and can be any value up to 1. RGB color method with transparency: color: rgba(143,1,122.5) RGB color method without transparency: color: rgb(143,1,122) Old color method using Hex example: color: #8F0179 Here is an example of the difference in the CSS for a font color: It is a good idea to begin to convert your colors to RBG now that CSS3 provides an alpha transparency value for RBG colors. This link has been added to my Image Resources page so check it out if you need a very quick color conversion between RGB and Hex values. No more opening up Adobe Photoshop or Fireworks to simply get an RGB or Hex color converted. There is a really simple RGB to Hex converter that works really well.
