Marlin: [BUG] MKS Robin tft V2.0 don't work- There are no buttons to move in the menus.

[NachoFrutos]

Hello, today I have downloaded the latest version of marlin 2.0. I have compiled and generated the .bin file for the mks_robin board. And on the TFT screen you only see the information of the values. but noy there are buttons to enter the menus. attached configuration files.

The Marlin status screen is meant for displays with a dial button - it has no on screen button - even if it does, it would not be touchable. You'll need to use the touch interface that came with your TFT.

Here is a great how-to tutorial by Chris' Basement: https://www.youtube.com/watch?v=f651bIg4SCo

@shitcreek These boards have a tethered "dumb" tft that when the Robin is flashed with stock Marlin, they revert to the basic 12864/Marlin UI with touch buttons underneath (something like this, it's probably changed):

They worked when I originally submitted the pins for the Robin boards, but code around the TFT has changed enough to break and I don't have physical hardware to test with for further debugging.

Maybe @tpruvot has some insight since those changes broke original functionality for the Robin TFTs 🙂

[shitcreek]

I stand corrected.

It's also what is holding up working Tevo Nereus configs unless @zillarob has some good news.

//#define TOUCH_BUTTONS
According to your config, you forgot to enable Touch Buttons.

Configurations, please
Please ZIP up your Configuration.h and Configuration_adv.h files (as
requested in the Issue template) and drop them into your next reply.
We'll check them over and see if anything is amiss.

Topic starter attached config to the first post... and TOUCH_BUTTONS are not defined there.

[boelle]

uppsi, did not see the link to config :-(

I havent played with that one for a bit, may have to break it out again.

Like Kos said above though, he needs to start by enabling the buttons.

[tpruvot]

there is a sample config in marlin

[boelle]

We need actual config and not example ones??? Or did you mean the example config was a starting point?

[tpruvot]

i tested it ok during the last fix... with the sample in marlin tree, the one also used for travis test..

[boelle]

so is this one an user error with the config?

[boelle]

posted on behalf of @tpruvot

[tpruvot]

was a test when i fixed the TFT in the last commit/PR

[boelle]

but my question remains, is there a bug in marlin or is it a user error (config error)

[tpruvot]

look like an user side error, if he didnt enable touch buttons... cant be working touch buttons

oki will close then

we can reopen if its a true bug

Hello, activating the #define TOUCH_BUTTONS option. the buttons appear but now it does not work when the button is pressed. I guess you have to calibrate the screen because with the values ​​of mks robin tft v2.0 it doesn't work. Is there any documentation or video that explains how to calibrate the screen? I test the screen when the board is connected by usb. I have no connected drivers or temperature sensors.. thank

[tpruvot]

even with wrong calibration values, the screen should be clickable somewhere... mirrored or rotated...

I did my test with the pasted values, and as you can see on the picture, its the V2.0 too

Makerbase updated their Robin repo recently, so could someone check if their version works still? I don't own any Robin/Robin Nano boards, so I can't help debug on that front.

If that code works, then it should be easy to port whatever settings/changes they made to get these tethered TFTs working properly on all Robin/Robin Nano boards.

Hi, I deleted all the files and downloaded the latest version marlin again. I have compiled with the sample files of mks robin. And everything works. Thank you very much. It can be completely closed. The problem has been user configuration error. I am very sorry for the waste of time and thank you all very much.
