Re: Is it possible to use LCDs with ST7735&ST7739 controllers??

While I'm waiting: How can I use the Sensor HX711 and SSD1306 on a WemosD1? HX711 -> is in Collection A SSD1396 -> is in NORMAL DISPLAY CLIMATE I could use another hardware with 16 MB, but in terms of power/speed a WemosD1 would do. The TTGO device has a Flash Chip Real Size of 16384 kB, which would...

Re: Is it possible to use LCDs with ST7735&ST7739 controllers??

To avoid having to type or copy a lot of commands to be executed for testing the display, you can put that information in the Line 1 .. Line 24 fields in the configuration. My usual content, depending on the hardware, usually looks something like this: Line 1: ~txc,yellow,blue~~txs,3~ESPEasy Line 2...

Re: Is it possible to use LCDs with ST7735&ST7739 controllers??

next checks:

flashed Y:\Temp\Bin-ESP32-display_ESP32_4M316k-20240309_PR_5003_8215939347\ESP_Easy_mega_20240309_display_ESP32_4M316k.factory.bin

no chnage vs. the max version. All ST7789 settings remain dead, ST7735 works better

Hi Ton, thanks.

Re: Is it possible to use LCDs with ST7735&ST7739 controllers??

It's the library. Good morning. I tried to compile/flash the https://github.com/Xinyuan-LilyGO/TTGO-T-Display/blob/master/TFT_eSPI/examples/FactoryTest/FactoryTest.ino with the help of Arduino - but got a compilation error. Currently installed was the TFT_eSPI lib from Bodmer. When I substituted it...

Re: Is it possible to use LCDs with ST7735&ST7739 controllers??

Hi guys, I was about to give up, especially since the amount of similar devices and information might be misleading. During my working in IT my motto always was 'Giving up is not an option - but it's not always easy'. And guess what? The display works again! I had the same idea that TD-er had, but d...

Re: Is it possible to use LCDs with ST7735&ST7739 controllers??

ok, sorry. I should have been clearer. "Support/Quick start: I started following the detailed example ..." was referring to the description on the LILYGO product website. Right now the situation is as follows: ESPEasy Mega is working on the device. The NodeMCU is working, I can configure e...

Re: Is it possible to use LCDs with ST7735&ST7739 controllers??

Technically, it's possible the display is broken. Well, that was one of my first thoughts. After delivery it was fine. I handled it carefully. Only possible option to me is a misconfiguration in ESPEasy ??? At the official lilygo product page I think I've found this 16MB board, the one marked "...

Re: Is it possible to use LCDs with ST7735&ST7739 controllers??

Have you tried to put some plain text, or variables from the Tools/System Variables page like %ip% or %sysbuild_filename%, in a few of the Line 1..Line 24 fields? That's the easiest way to put some content on the display 8-) Just tried it, no luck. I still have only a dark grey screen, so it's hard...

... a LilyGO/TTGO T-display (https://de.aliexpress.com/item/1005005970553639.html). This is the exact model you are using? If so, what hardware version you have (should be on the silk-screen somewhere), as LiliGO has a 'habit' of changing some, sometimes crucial, details on newer hardware revision....

Re: Is it possible to use LCDs with ST7735&ST7739 controllers??

If you ever think of switching to any other display, ... Well, I have other displays already :D. Just shopped around Aliexpress and found this interesting combination of controller plus display. As an engineer giving up is no option, I want to know where the problem is or which mistake I made ;) ;

Re: Is it possible to use LCDs with ST7735&ST7739 controllers??

Maybe also check if it really is this display controller chip. Wouldn't be the first time a seller sells something different from what was advertised. Well, I took a picture of the device and enlarged it. I only can identify the ESP32, the CP2102 and the Flash storage. I guess the graphics chip is ...

Quick response in-between: When I enter "gpio,4,1" and "gpio,4,0" on the tools page the display goes from black to dark grey and vice versa. I tried to change GPIO ← MISO: from 17 to 'None', that gave me an error saying that SPI is not configured properly. So I tried GPIO-37 inst...

Hi, even though this post is a little bit older, maybe somebody can help me. I got myself a LilyGO/TTGO T-display (https://de.aliexpress.com/item/1005005970553639.html). According to https://espeasy.readthedocs.io/en/latest/Plugin/P116.html this device is supported. The delivered device had the demo...
