1.8" inch ST7735R SPI 128*160 TFT

Cenxiones de pines (con esto ya podemos usar programas en python sin
agregar modulo al kernel):

Agregar modulos al kernel:

HAbilitar con raspi-config, el modulo SPI:

The SPI interface is ena.bled 

cargar modulos al kernel:

modprobe fbtft_device name=flexfb

modprobe fbtft_device name=sainsmart18 speed=16000000 rotate=270

I've activated SPI in raspi-config, and I've added fbcon=map:10 fbcon=rotate:1 fbcon=font:ProFont6x11 in /boot/cmdline.txt, but I see nothing but a white screen.

A modprobe fbtft_device name=adafruit18 gives the following:

Code: Select all

Plus, /dev/fb1 appears after the modprobe. 
There is also no luck in xorg - using /dev/fb1 in /usr/share/X11/xorg.conf.d/99-fbturbo.conf for fbturbo is not contributing. The white screen is residual. But the x startup was only a test, in the end I'd like nothing more than a console. 

Any ideas?
