12/12/2023 0 Comments Arduino tft displayI've also added support for some additional displays, so it now supports 16 different TFT displays. This means that you can use any assignment of pins to the four I/O lines needed by the display, and makes it about twice as fast as one using SPI calls. Unlike my Compact TFT Graphics Library which uses standard Arduino SPI calls, this library uses direct I/O pin manipulations. ![]() If you need more pins choose a larger chip, such as the ATtiny84 or ATtiny404. This leaves one pin free on an 8-pin chip such as the ATtiny85 or ATtiny402. This library supports TFT displays that use an SPI interface and require four pins to drive the display. I've included demo curve-plotting and histogram-plotting programs that adjust to fit any display. ![]() This version adds the ability to plot outline rectanges, and outline and filled circles. Like the original library it allows you to plot points, draw lines, draw filled rectangles, and plot characters and text with an optional scale factor, in 16-bit colour. It's an updated version of my Tiny TFT Graphics Library. This latest version of the library supports both the classic ATtiny processors, such as the ATtiny85, and the new 0-series, 1-series, and 2-series ATtiny processors, such as the ATtiny402.
