ILI9341 not working

[damian_py]

Hi everyone,

I have spent the last two weeks on trying to use the ILI9341 SPI display.

Neither the Loboris TFT driver nor other works. They all work perfectly on ESP Wrover kit, but do not work on ESP32 Wroom kit. I tried different pin configuration and changed the code, but none of them worked.

Does anyone has a tested driver on ILI9341 display? I ordered 4 displays like this one, it works on none of them.

Thank you for your help.

I've tested the library on a similar board (only with touch panel) and there was no problem.
Can you be more specific about what exactly does not work?
You have to connect +5V to display's Vcc or to short the jumper J1 and connect Vcc to +3.3V.
Of course, you also have to connect LED pin to +5V.

Hi,

I am also trying to hook-up my Esp32 to the ILI9341

I am trying to build and flash the ESP32_TFT_library to my ESP32, but i am getting the same error over and over. (i am on windows 10 and using Mingw32). I have the latest version of the esp-idf from git and also your latests update of the ESP32_TFT_library. Why am i getting this error and how to fix this?

Hi Loboris,

Thank you for your answer. In fact it was just that I had not pulled the reset pin to +3.3V. Now it works.
Currently my problem is driving the ESP23S17. Do you have a library for this SPI chip?

Thank you,

Damian

I am also trying to hook-up my Esp32 to the ILI9341

It is caused by the latest changes in esp-idf.
For now, just comment the line 836 in components/spiffs/spiffs_vfs.c
The fix will be pushed soon (I'm working on some other changes too).

I've never heard of ESP23S17 and can't find any info on it.

Thank you Loboris, that did the trick!

Sorry, I was thinking about MCP23S17 by microchip, the SPI equivalent of the MCP23017.

Hi Loboris,

I am trying to combine the SD card example code (included in the esp-idf) with the ili9341 TFT library to display my images to the screen from the SD-card. I had the SD card example working both in SPI mode and SDMMC mode, but want to use the SPI mode, because it takes up less connections and components for my final setup. I have searched, but haven't found an example anywhere that combines your tft library with an SD-card. So therefore i wanted to combine the code myself. When i want to make all , i get the error messages below, saying that the SPI libaries of the sd_card example collide with the SPI_loboris libaries of the TFT. What can i do to fix this? Or is there another way to use an SD-card with your library so I can load the images from the SD-card on to the TFT screen?

Regards,

Stefan

Thank you for reporting the issue, I'll check it and try to fix it.
