Is it possible to use a gLCD (ST7565) with Marlin assigning arbitrary pins for driving it? I mean is it possible to use a kind of Software SPI or only HW SPI is included?
I explain better my problem: I have a megatronics v2.0 and an adafruit gLCD 128x64 based on ST7565. I want to use some spare pins on the “keypad” connector considering that in the same connector the encoder pins are present and the remaining pin are exactly 5 needed for the display. If I use the ST7565 library provided in the adafruit tutorial everything is OK because I can assign any digital output pin for SID, SCLK, CS, RST, AO ecc… but Marlin uses U8Glib library and I understand that uses the HW-SPI and you can assign the other two remaining pins (A0 and CS if I remember well).
I check the U8glib website and it seems that support Software SPI, so my question is if in marlin there is already a configuration for this. thank you
