Did Thomas ever record the LCD-guide?

Post by daspunner » Fri Mar 09, 2018 9:45 pm

In this article aswell as the Youtube-video https://toms3d.org/2017/12/09/tmc2130-guide/ Thomas says that he will record another video/guide where he will show how you can use an LCD together TMC2130 connected with SPI. Did he ever record/write that guide?

Nope, not yet! Still waiting for that one, too.

there is nothing special.

The aux3 is used for the sd card.
You can use lcd normally / but you can't use the sd card then.
Both can be configured separately.

Hence I'm using TMC2130 only for X and Y I've re-used E0 and E1 pins so I don't dip into free Servo pins.

Edited pins_RAMPS.h file:
#define X_CS_PIN 53 to 42
#define Y_CS_PIN 49 to 44
#define E0_CS_PIN 42 to -1
#define E1_CS_PIN 44 to -1

Soldered SDO SDI and SCK to LCD "riser board" pins directly (it's shared signal anyway) n plugged corresponding CS pins in to AUX-2 (D42 and D44).

Done, SD card print initiated from the 12864 LCD with TMC2130's...

Hope this helps.

The reprapdiscount full graphic controller doesn’t connect to the SPI port on RAMPS, it uses software spi instead. Part of the reason why it’s so slow.

The SD card does use SPI but that really shouldn’t matter; you should be able to use it in conjunction with TMC2130 without a problem.
