IMPORTANT: There is an omission in the video, for the touch screen to work you must un-comment the line below (remove the hash at the beginning) in the "User_Setup.h" file.
#define TOUCH_CS 21 // Chip select pin (T_CS) of touch screen
How to wire up and use a ILI9341 TFT LCD Display with an ESP32, uses the TFT_eSPI library. Covers all aspects - The display, SD card and touch screen with examples for all. Apologies for the varying sound levels. Video was shot over about 10 days and I must have positioned the Mic differently on some occasions and for some shots I used a different mic.

Magnificent guide - I now have the Display section up. Didn't work first time - tried in Arduino 2.0.0 rc9.4 - lots of critical errors compiling - updated library, boards etc still failed Using ESP32 Wemos Lolin32 and 2.8" ILI9341 TFT LCD. errors like undefined min(_h,_w) etc, got the latest tft_eSPI from GIT hub, same no matter what example I tried. So I deleted all my arduino installations, and folders, Libraries etc. Then installed fresh IDE 2.0.0 Rc9.4, added ESP 32 boards , added tft_eSPI from the IDE 2.4.72, edited the User_Setup.h file as advised, compiled with a few warnings about the Changed pin assignments - but no errors, Uploaded - and I'm a happy man! many happy displays.

All very helpful. I wired everything up as all the diagrams that I found, modified my TFT_eSPI setup file with the right settings, turned on and nothing. After a while, I tried following your instructions to the letter, wire colours and all and it worked, even though everything I had done was exactly what you did, though I used an orange wire for CLK and a green for data, so maybe that was it. (Only kidding, I suspect that I've got a duff wire or a duff connection on my breadboard), but hey, thanks. Forget TFT_Meters, the TFT_Matrix example is super!

Great presentation! I did run into a minor problem with the Meters script, was getting 6 warnings "ISO C++ forbids converting a string constant to 'char*' " and pointed to 6 lines (44-49) in void setup. Although the script compiled and loaded fine and the meters displayed beautifully on my display, I still did not like having those warnings. Did a little research and learned that Warnings usually mean that your program may or may not work. Those 6 lines called a function (plotLinear() with three parameters, the first of which was "A0" thru "A5". Located the function void plotLinear(char *label, int x, int y) and changed it to void plotLinear(const char *label, int x, int y) and the warnings disappeared. Script compiles and loads and runs just fine.

@andreasbjerreovergaard4641 3 года назад

I would recommend connecting touch cs to screen cs so you can keep pin 21 for i2c as for instance a bmp pressure sensor will spam the touch with input. Remember to change #define TOUCH_CS. Thanks for the project but i think it needs wiring diagrams.

@JayUnderCover Год назад

Is this possible because the touch controller is only sending data to the esp32, and the display controller is only receiving data from the ESP32. So they can technically run at the same time anyway? Does this speed things up so the display doesn't lag behind the touch input?

@XTronical Год назад

I'd have to Check but as long as the touch controller waits until the esp32 is ready to receive data after generating its interrupt then should be OK. But would have to examine library's. As if esp32 half way through sending data to screen and starts servicing the touch then could cause corruption. The potential is there, I just haven't looked how the library's work

@hl293 4 года назад

Thanks so much for this video! I've got a question. These display boards have a jumper "J1" for selecting the voltage. In your case for the ESP32, did you need to short this jumper "J1"? Just want to confirm before I do something stupid with my board...

@XTronical 4 года назад

Yes, short the jumper if using ESP32, leave alone (how they come by default) if using Arduino. Nothing bad happens either way for ESP32 apart from it may not work if you do not short it. Mine worked and then stopped when I added one more component to the project. For Arduino it may break the screen if you short it so leave un-shorted.

@randomsporadicprojects8941 4 года назад

Very useful - thank you. Spurred on by your demo I've now got a touch screen gui for my home automation :) Are you aware of any way to control the backlight? - all I've seen so far are mentions of cutting traces and soldering a transistor.

@XTronical 4 года назад

Yes, just connect it to an output pin instead of vcc. Setting pin high will turn it on, low off. You could even use pcm to give varying brightness. Arduino's and esp32 outputs can cope with the current required, although you could measure it first if you wanted to be doubly sure.

Hello @bens4446, can not follow the assignment portion of the video, can you help me fill in the blanks so I can get going? Display Pins - ESP32 GPIO Pins VCC 5.0V or 3.3V GND GND CS RST DC - I belive is 23 MOSI SCK LED 5.0V or 3.3V MISO TCLK TCS TDIN TDO TIRQ SD_CS SD_MOSI SD_MISO SD-SCK

If both CS are running on PIN 5, it does not work. For SD another PIN should be selected. In the setup SD.begin(PIN_X) should be called.

I want to make it with the Relative Humidity reader just like you show. Can you show how to make it save data to a data logger? I am doing atmospheric research. I want to create a device that can be worn that will collect data in different environments inside and outside. Because it is wearble, I don't want it bulky or heavy. The data logging is for reviewing at a later date away from the location. Thanks

Did you mean this comment to be under the humidity sensor video I did? Anyways, basically you'll need to hook up to a sd card interface (videos on this) and make the Arduino go into deep sleep to save power (as battery powered) and just save to a text file on sd card in comma delimited format. This will load up straight into excel etc. I've done a weather centre project which shows deep sleep and sd card etc.
