Library to control a Graphics TFT connected to 4-wire SPI - revised for the Raio RA8875 Display Controller.

Dependents: FRDM_RA8875_mPaint RA8875_Demo RA8875_KeyPadDemo SignalGenerator ... more

Enhanced touch-screen support - where it previous supported both the Resistive Touch and Capacitive Touch based on the FT5206 Touch Controller, now it also has support for the GSL1680 Touch Controller.

WiredHome	78:faf49c381591	3	///
WiredHome	78:faf49c381591	4	/// The RA8875 Display controller is a powerful interface for low cost displays. It
WiredHome	190:3132b7dfad82	5	/// can support displays up to 800 x 480 pixels x 16-bit color.
WiredHome	167:8aa3fb2a5a31	6	///
WiredHome	182:8832d03a2a29	7	/// @image html Example_Program.png "Image of an Example Program"
WiredHome	182:8832d03a2a29	8	///
WiredHome	190:3132b7dfad82	9	/// Aside from 800 x 480 pixel displays, another common implementation is
WiredHome	190:3132b7dfad82	10	/// 480 x 272 x 16 with two layers. The two layers can be exchanged, or blended
WiredHome	190:3132b7dfad82	11	/// in various ways (transparency, OR, AND, and more). It includes graphics
WiredHome	190:3132b7dfad82	12	/// acceleration capabilities for drawing primitives, such as line, rectangle,
WiredHome	167:8aa3fb2a5a31	13	/// circles, and more.
WiredHome	167:8aa3fb2a5a31	14	///
WiredHome	190:3132b7dfad82	15	/// It is not a display for video-speed animations, and maybe could hold its own
WiredHome	190:3132b7dfad82	16	/// as a slow picture frame, at least when using the SPI ports. How the performance
WiredHome	167:8aa3fb2a5a31	17	/// differs using I2C, 8-bit parallel or 16-bit parallel has not been evaluated.
WiredHome	167:8aa3fb2a5a31	18	/// Certainly the parallel interface option would be expected to be a lot faster.
WiredHome	167:8aa3fb2a5a31	19	///
WiredHome	167:8aa3fb2a5a31	20	/// What it is good at is performing as a basic display for appliance or simple
WiredHome	190:3132b7dfad82	21	/// home automation, and because of the built-in capability to draw lines, circles,
WiredHome	190:3132b7dfad82	22	/// ellipses, rectangles, rounded rectangles, and triangles, it does a lot of the
WiredHome	167:8aa3fb2a5a31	23	/// work that your host micro would otherwise be doing, and in many cases it does
WiredHome	167:8aa3fb2a5a31	24	/// it much faster.
WiredHome	78:faf49c381591	25	///
WiredHome	167:8aa3fb2a5a31	26	/// While it is good to know about Bresenham's algorithm (to draw a line) and how
WiredHome	190:3132b7dfad82	27	/// to implement it in software, this controller simplifies things -
WiredHome	190:3132b7dfad82	28	/// You just give it (x1,y1), (x2,y2) and tell it to draw a line.
WiredHome	167:8aa3fb2a5a31	29	/// Without the hardware acceleration built into the RA8875, the host would have to
WiredHome	167:8aa3fb2a5a31	30	/// compute every point, set the graphics cursor to that point, and fill in that
WiredHome	167:8aa3fb2a5a31	31	/// point with the target color. A diagonal line of some length might take 100
WiredHome	190:3132b7dfad82	32	/// interactions instead of just a few. Other drawing primitives are similarly easy.
WiredHome	167:8aa3fb2a5a31	33	///
WiredHome	190:3132b7dfad82	34	/// It has some built-in fonts, which can be enhanced with optional font-chips, and
WiredHome	167:8aa3fb2a5a31	35	/// with the provided software font engine, and a few instructions, you can convert
WiredHome	190:3132b7dfad82	36	/// most any True Type Font into the data structures suitable for this display.
WiredHome	167:8aa3fb2a5a31	37	///
WiredHome	167:8aa3fb2a5a31	38	/// To round out the features, this library offers the ability to render Bitmap (BMP),
WiredHome	190:3132b7dfad82	39	/// Icon (ICO), Join Photographic Experts Group (JPG), and Graphics Interchange Format
WiredHome	190:3132b7dfad82	40	/// (GIF) images. These are implemented primarily in software, taking advantage of the
WiredHome	190:3132b7dfad82	41	/// hardware acceleration where it can.
WiredHome	167:8aa3fb2a5a31	42	///
WiredHome	190:3132b7dfad82	43	/// When you are satisfied with what appears on screen, there is a PrintScreen method
WiredHome	167:8aa3fb2a5a31	44	/// to pull that image back out and write it to a file system as a BitMap image.
WiredHome	101:e0aad446094a	45	///
WiredHome	78:faf49c381591	46	/// The controller additionally supports backlight control (via PWM), keypad scanning
WiredHome	167:8aa3fb2a5a31	47	/// (for a 4 x 5 matrix) and resistive touch-panel support. Support for capacitive
WiredHome	167:8aa3fb2a5a31	48	/// touch screens is also integrated, in a manner that makes the resistive and
WiredHome	190:3132b7dfad82	49	/// capacitive interfaces nearly API identical. The capacitive touch support is for
WiredHome	167:8aa3fb2a5a31	50	/// either the FT5206 or the GSL1680 controller chips.
