Thanks a ton, it worked like a charm, and for the adafruit 1.8" clone, the gpio was the same "no MISO":
MOSI - 19, SCK (SPI_CLK) - 23, CS - 24, RESET, DC and LED - 11, 13, 15. power supply and ground as usual
and the modprobe is:
sudo modprobe fbtft_device name=adafruit18 gpios=reset:1,dc:0,led:3 speed=16000000 fps=25 rotate=90
thanks again and keep up the good work.
