Different components configure

[baogiadoan]

Hi,

I tried to buy the same components as your spec, but it seems that there are some slight differnce and after 100% sucessful build, it didn't work at all.

Can you help to guide me how to configure with my components here, as I try to plug in as far as I know but the LCD is not working and didn't show anything.

It's different screen. We use SPI interface while yours is some kind of parallel one. Can you send exact model name of your screen?

As I remember we used this one: https://ru.aliexpress.com/item/2-8-320-240-SPI-TFT/32847628219.html

this is also SPI, I tried to buy the same but somehow it's differnt Here is the one I bought on ebay: https://www.ebay.com/itm/223145284611 FX- 2.8" 240x320 SPI TFT LCD Touch Panel ILI9341 5V 3.3V for Arduino RPi ESP8266

On your foto I see 8 pins for LCD connection, but SPI interface requires only one (for data transfer): https://en.wikipedia.org/wiki/Serial_Peripheral_Interface

Also some of your wires connected to SD-card pins, which is not used in current project.

I tried to find the datasheet of that one, but it seems that it's from China and no documents about it.

I have another SPI OLED LCD here, can you see how to plug it with your module? [image: OLED128_pins.png] https://core-electronics.com.au/freetronics-128x128-pixel-oled-module.html

Btw, is the configuration on your picture is correct? As I see the diagram both connectors are nearly identical and parallel, but your real picture is different.

Btw, I didn't see the pins XCLK, PCLK from Camero connected to any where in the diagram? And pin D1 and D3 seems to be flipped? is that correct?

[ZFTurbo]

I will be able to check device connections at Monday. I will post if diagram is totally correct then.

[ZFTurbo]

We checked connections today. It must be like that: https://github.com/ZFTurbo/Verilog-Generator-of-Neural-Net-Digit-Detector-for-FPGA/blob/master/images/Connection-scheme.png

We updated picture in project.

I also made 2 fotos. Connection scheme can be restored from them: https://raw.githubusercontent.com/ZFTurbo/Verilog-Generator-of-Neural-Net-Digit-Detector-for-FPGA/master/images/Conn-Foto-1.jpg https://raw.githubusercontent.com/ZFTurbo/Verilog-Generator-of-Neural-Net-Digit-Detector-for-FPGA/master/images/Conn-Foto-2.jpg
