[Question] Connecting ESP32 to the MKS TFT24

[primus192]

Hi. I have got printer with MKS GEN L board. My printer have MKS TFT24 touchscreen connected to AUX1 port. As i am concerned, this is the only usable serial port on the board and if i wanted to use esp3d i need to disconnect the touchscreen... However my TFT24 touchscreen have WiFi port on the back. Can i connect my ESP32 Devkit v1 to this WiFi port and somehow route the esp3d to mainboard via this connector? Can you give me any advice how to do this? Thanks!

Thank your for submiting, please be sure you followed template or your issue may be dismissed. if you deleted the template it is here

you cannot use same serial port for esp board and TFT, both are doing queries and the data flow willl be merged inconsistantly
Connecting ESP32 Devkit v1 to TFT WIFI port will work for moniitoring but unlikly for file upload - the file upload need super clean signal due to usage of very high baud rate, and with esp 32 devkit connected by cable will will have some EMI noise for sure that will corrupt high baud rate transfert

Okay, so what type of connection this issue covers? #523

[luc-github]

MKS WIFI devices connected with MKS WIFI module

[primus192]

So i cant upload esp3d on the module shown on the photo?

[luc-github]

this one is not an esp32 dev kit, it is MKS WIFI module, so it works (file upload)

In all ESP moduleS the esp3d FW can be loaded

[primus192]

Ok i see it is esp8266, so my esp32 should work if i correctly connect it. Will give it a try, thanks.

[luc-github]

no that is my point - put esp3d on it is not the issue
file upload / transfer may not work due to your connection having emi noise, but it may also work if you are lucky

[primus192]

I will try to connect it with shielded cable and will send you feedback/screenshots, thanks :)

#define COMMUNICATION_PROTOCOL MKS_SERIAL
This is needed?

[luc-github]

This is needed to uncomment it?

//MKS_SERIAL Mks protocol

no this the value to put as reference
read this : #620

Got a problem with uploading webui, it says file upload failed(13)

[luc-github]

It means size error
can you do a screenshot of page with error ?

[primus192]

[luc-github]

I think you FS is corrupted - you should not have 95.60KB used space if nothing on FS
go to Terminal tab and click on it
type [ESP710]FORMAT wait for format done then refresh page and try upload again

[primus192]

Still failing

[primus192]

I tried to push this file manually via VSCODE to the esp32 it works but when i click od ESP3D white screen appears and nothing is shown

[luc-github]

I am confused what board did you flashed ?

[primus192]

Esp32 Devkit V1

[luc-github]

what env did you selected in VS CODE ?

[primus192]

I just manually uploaded index.html.gz to the spiffs, because i couldnt do it via 192.168.0.1

[luc-github]

This is not my question - what env did you selected in VS Code for flashing your ESP32 ?

[primus192]

I flashed my esp32 via Arduino IDE

[luc-github]

what settings did you used to flash in arduino then

[primus192]

Ok i selected wrong board, it is working now

[luc-github]

You need to define the target FW - it is Marlin in your case, and also you need to enable TFT SD and TFT USB in settings

[primus192]

Its working.. Thanks ;)

[luc-github]

Good I move this to discussion area then

[primus192]

I am not able to enter marlin settings in my setup is this normal when using mks tft protocol?

[primus192]

Also, there is no heatbed temperature control.

[luc-github]

yes : #620
you need to enable poilling commands and put M105 in it, the control will apear when answer is detected
