MKS SBASE (v1.3) + MKS mini 12864 LCD (v1.0) + SMOOTHIEWARE (version Jul 31, 2020)

[davigre]

I have a MKS SBASE v1.3 working with Last Smoothieware version + MKS TFT 32 + Octoprint.

I buy MKS SBASE + MKS mini 12864 on Feb of 2018, but was until now that I have time to mount both items in my Delta printer.

The only thing that rest to mount and finish this project is the 'MKS mini 12864 V1.0'.

I already found that is not a 'only connect cables' thing. But I know that can be done because the photos on #101

I follow #101

and checking MKS mini 12864 pint outs

I do not solder the SBASE (need to unmount a lot of things to do that) so what I do was connect with cables to the required pins on EXP1:

MINI12864 <-> SBASE
(DOGLCD_AO) <-> (P0.15)
(DOGLCD_CS) <-> (P0.16)
(BTN_ENC) <-> (P1.30)
(BEEPER) <-> (P1.31)
(GND) <-> (GND)
(VCC) <-> (VCC)

EXT2 without modifications, connected with ribbon cable.

I don't need SD, so I do not enable it in 'config' file.

panel.bed_temperature                       60              # Temp to set bed when preheat is selected

I already try changing different parameters in my config.

The good news is that MKS MINI 12864 turns On and ENCODER, BEEPER works also. Even the 'STOP' button. I know because I play with the encoder and the SBASE is executing commands. So the only thing that is not working is the display.

@makerbase-mks, can you check please. What I'm doing wrong?

Finally the key was this image

Notice that I do not enable 'external_sd', no problem, you can access MicroSD from the board.

HELLO ,
I found the something, why your P0.15 is different form mine?

But I think your pin map is right..
Because I found out from the source code:

it defines the SPI channel by default 2 set in it , I think this is the reason you have to change SPI Channel and re-porting your pins.
