PI 2, TFT LCD 480*320, SPI & Touch Screen on Windows 10 IoT, working demo, more can be found at https://www.youtube.com/c/thebreadboardca
Story
OK, so i think I am outdoing myself with this one
ILI9488 480 * 320 LCD 65K colour display
TSC2046 touch screen cotroller
ILI 9341 320 * 240 LCD 65K colour display
HX8357 480 * 320 LCD 65K colour display (Not tested but converted still)
8*6 Font integrated
11* 16 font converted but not integrated
line draw
Arc, Circle
Character from Font
Pixel Point
Image Load etc
wow, some coding marathon there
so following the demo by Graham Chow who provided the basic initialization routines for a 9341 display, I took it alot further and added basic vector functions like line draw, pixel draw and character draw routines along with optimized SPI transfer routines resulting in the provieded set of libraries supporting a few more display chips
there not perfect, but are functional, they probably need more bounds checking and limit checks but they do work well and as fast as an be considering the limitations of the MS SPI implementation
Here is the UI
all the buttons work to the smaller display area in the top right of the main display (Minions graphic area)
some are pretty obvious as to their function, the smaller sub buttons load various images I happen to randomly pick off the internet to demonstrate the ability to load to the LCD SPI screen as well as the HDMI (See the video for a demo)
the DEMO button runs through the same basic set of routines that the Sharp96 demo used. Rectangle fill, line draw, arc, circle and various text writing with different font sizes
The difference here is that all this is also invokeable from the touch screen via a finger or a pen on the touch panel, in addition, if the calibration if the touch screen has not been completed it will invoke on start up and then save the results to the SD card for automatic load at next startup, not only is this hand for the touch screen but shows how any value can be saved o the SD card for future use through restarts etc.
The code is attached so enjoy and please ask questions
This represents a lot of effort so please be respectful of your feedback, you can use it as you please and I look forward to comments and suggestions for improvement, there are areas for improvement and optimization I know and not all the error handling and bounds checking are in place but it works well and it seems to be stable so I hope you find use for it and if possible, you extend it and re-share with the community.
I hope you find use for it!
