This can be a real time saver to speed up the display (espaecially on a lowly AVR), but this trick does not work over SPI. If you write a horizontal line from a databus which has the same widht as your colors then you can simply output the data once, and toggle the write pin for each pixel. Stuff like initializing the displays, setting a window and tricks for writing horizontal lines. In the bottom layer you talk to the hardware, whether SPI, or an 8 or 16 bit databus.Ībove that you have a layer with hardware specific routines. Settings for gamma correction, display resolution and rotation ( The ILI chips rotate your data in hardware!) It does things as, defining how many colors you want to use (monochrome, 8-bit, 16 bit in 565 (RGB) fromat or other. Initialisation of these displays consists of writing some 30 odd bytes to them.

I've dabbled a bit with the source code of Rinkydink's UTFT, and it takes some time (an afternoon or so) to get the hang of it, but I think the way they have sovled making the lib compatible with different display controllers quite usable.

The ST7735 displays also have an SPI interface, and I've read several posts of people prefering these above the ILI displays.ĪVR is a bit slow for these displays, and platforms such as mbed & 32 bit processors or anything with hadware SPI with DMA seem a better fit.Īny MBED library is probably pretty easy to port to 8-bit AVR, as long as it is written in C / C++. With a pin pitch of 40 micrometer and the chip glued to glass it would be quite a challenge to change that, which means you are stuck with the signals accesible through the flex cable. (some of) those ILI displays support an 8 or 16 bit's databus, but also SPI and I believe it is done by pulling some configuration pin high or low. The ILI93xx or ILI91xx seem to be popular and well supported.

I run some demo's of Adafruit and of UTFT, then decided AVR's were too slow which started a foggy maze around STM32.įor small TFT displays the search is usually for the controller chip that is supported by the library you want to use. My own experiences with TFT displays is quite limited. The magic word for the diplays you mentioned in #7 is: 'nextion', and they are sold by itead, seeed studio and the usual Ali / Ebay / Chinese resellers.įor ruggedness milling a hole in an aluminimum box and then simply pooring glue around the edges from the inside seems the simplest solution.Īll of the TFT breakout boards I've seen also have a uSD connector on the back, and if it doesn't you can always add your own, or some dataflash chip.
