Thanks for the reply buuuuut…
2 of the RGB pins are connected to the SCK and SDA pins.
spi:
clk_pin: 47 # sck
mosi_pin: 41 # sda
And you can’t use “aloow_other_uses…” with spi apparently, I’m probably missing something real simple here, but X referencing all the pins I’m in the right place
What is your full yaml?
So, i managed to get the yaml to compile using “allow_other_uses”
No more errors.
The back light, haptics, LEDs around the rotary bit, button and rotary all works, using it on my shelly dimmer in the lounge.
Still cant get anything on the screen, but hopefully tomorrow that will be resolved, found the drivers to download in ESPHome dev branch.
TBC…
I have the same problem on the WT32S3-21S (ZX2D10GE01R-W4848). My esphome code compiles and I can get all the hardware working except for the display to show anything.
Maybe there’s some init sequence I need? I plan to dig in the sample C code to see if there’s anything relevant once I find the time.
Below is an excerpt my display code. I’ve included some options below which enables PSRAM which is required for the display to work (otherwise it boot loops) and to choose the correct flash_mode.
Edit: added init sequences from sample C code and fixed data pin mapping but still no display being output…

Sorry but glad its not just me lol, did you try the test pattern under display settings? I tried still didnt work.
I feel like the st7701s driver isnt quite right?
for funsies (and my new air conditioner), i tried compiling it again. now it doesn’t show the display even. disabling all stuff except web_server, i can at least see… web server. into the trash pile this garbage goes. esp32s2 is an abomination and should not have been made.
wasted one too many hours to get wled working on one, with value for time wasted being not very good.

Ah, this topic has branched into multiple devices. My OG one was S2. so S3 won’t compile unless you change the YAML for S3 
And ddisplay is ST7701S so you have 15 x GPIOs for RGB and they are doubled up on SPI, quite painful. I’ve also tried LVGL with no luck. Im going to use a few of the settings you guys have used and post my yaml.
Lets compare YAML?
ZX2D10GE01R-V4848
FYI, I updated my yaml with yours just in case but still no go.
Do you need all of that init_sequence?

Here’s mine. I’m stuck on the display.
I’m not using any external_components. I’ve been trying to compare the code with others that have gotten it to work like this project and the sample code and with how esphome implements it here.
The init sequences used are different but I haven’t gotten either to work. I have no idea at the moment… if only there was a way to get more debugging output from the st7701s esphome component…

Still nothing for me, I’ll keep searching
Hello everyone, has anyone managed to get the ZX2D10GE01R-V4848 panel to work?
I have tried everything and I absolutely cannot get the display to work. By everything I mean everything…
not yet, but I may have a new init_sequence to try out, was going to check my config today and test it tonight when I get home, looks like there is a bit more chat arounbf the ST7701s at the moment on Discord. I’ll keep you posted
I found the thread on Discord you mentioned about adding delays to the init_sequence for the ST7701s ([st7701s] Add delay feature in init sequences by clydebarrow · Pull Request #7343 · esphome/esphome · GitHub), but I haven’t had much luck.
I know the wireless-tag sample code (ZX2D10GE01R-V4848/main/screen.c at ad21b3659527618fdd752cc0801b0a36f6c5e52c · wireless-tag-com/ZX2D10GE01R-V4848 · GitHub) has some delays sprinkled at the end, and I tried replicating this but no luck. Curiously the Arduino_GFX library which supports the ZX2D10GE01R, doesn’t have any delays in its init_sequence (st7701_type7_init_operations) (Arduino_GFX/src/display/Arduino_RGB_Display.h at b3d190810b8e8c6d558b72176a247b2eb811241d · moononournation/Arduino_GFX · GitHub)
Hey, yeah ive been trying with a lot of different init sequences that I’ve found online, but just cant get it going, assuming my device isnt buggered, delays is all thats left?
Ill try those init sequences
Had a quick look at the SPI initialization with a logic analyzer as I suspected there is something wrong with the way it’s being driven rather than the sequences being sent. I need to do a little more investigation but initial impressions are the SPI init sequence is going horribly wrong some how. The signals look all wrong. I’ll investigate further when I have time but it might give a hint where to look for someone who is a bit more familiar with it?
The SPI init sequence is the first block in this PIC below
There appears to be no MOSI or CLK from the SPI but the CS is asserted correctly (see below)
Is there an IO conflict between the parallel RGB_D1/LCD_SDA and RGB_D0/LCD_SCL during INIT?
A few quick mods to the ST7701s.cpp driver code and I’m very close. I followed the Wireless TAG example code https://github.com/wireless-tag-com/ZX2D10GE01R-V4848/blob/ad21b3659527618fdd752cc0801b0a36f6c5e52c/main/screen.c
If you look at the init from line 389 they do all the SPI before creating the display driver and then destroy it. Moving the this->write_init_sequence_(); fixed the SPI issue and copying and replicating delay values for SLEEP_OUT && DISPLAY_ON and I have the display up (but it has flickering so not perfect). I tried to access the discord chat but maybe I need an invite or something? Some tweaking to the driver code and this should work fine. Happy to assist / test but I’ve run out of time today.
WOW, looks like you have done loads of work here, I’m sorry I don’t know much about this stuff, I tend to stumble around until i hit on something by accident.
Is there something I should do in my yaml file or do we need to update the driver code?
