TFTLCD - SPI Register map #47

Closed bartokon closed 6 months ago

bartokon commented 2 years ago

Hi, Where can I find datasheet with SPI register Map for pmod_tftlcd-v1.1? From documentation, LCD driver IC is NV3047, but I can't find any information on that part. Thanks.

wuxx commented 2 years ago

hello the lcd is based on ili9341, please check here https://github.com/wuxx/icesugar/blob/master/doc/ILI9341_DS.pdf

@wuxx thanks for link! Is there an example design for this LCD in the repository?

wuxx commented 2 years ago

Hi, what do you mean the example design. the example code can check here https://github.com/wuxx/iceZ0mb1e/tree/master/firmware/main

Hey, Wuxx!

I have some questions regarding the LCD: The "RS" is "D/CX" port? And the LCD is configured to 4-spi mode? There is no other chip besides LCD on the PCB, is that normal? The LCD have inbuilt controllers? Does touch functionality work somehow? If there is no controller? How?

Sorry for these questions, but the documentation and schematics are lacking some important information.

bartokon commented 2 years ago

So, RS is D/CX, the LCD is configured in 4-spi mode. I still don't know about the touch functionality.

wuxx commented 2 years ago

hello, RS is DC (data/cmd), LCD is in 4-spi mode. the LCD have inbuilt controllers. currently the touch function is not supported on hardware

bartokon commented 2 years ago

Hi, "LCD have inbuilt controllers ... currently the touch function is not supported on hardware". So that means LCD is touch-screen ready, but icesugar is not? I'm writing my own drivers for the LCD in Verilog, so if the LCD is touch-capable, can you provide me with a data sheet for touch driver?

wuxx commented 2 years ago

Hello, touch is not currently supported on the hardware. Touch requires the circuit at the bottom of the board (based on xpt2046) and the support of the screen. All screens currently shipped do not have a touch panel installed.

wuxx commented 2 years ago

when we mentioned touchscreen, the touchscreen include LCD display and a Touch panel on top of screen.

bartokon commented 2 years ago

Okay! So last question that 3 little ic's are resistors/capacitors?

wuxx commented 2 years ago

yes, you can check the schematic.

hello good morning! I wanted to know if you still don't have something about the TFT screen for the ICESugar_1.5

I am investigating to find out how it works and implement it in projects with Verilog, myself also to test the TFT modules that I can buy. First of all, thank you for your time and I hope to contribute something to you in the future.

hello, the screen is based on ili9341, there should be lot of document, just search the 'ili9341' in google

wuxx commented 1 year ago

ILI9341.pdf here is the spec, please check.
