Hi!
I have tried to get the new Esplora TFT (ROBOT LCD) to work with my RaspberryPi using the FBTFT driver (GitHub - notro/fbtft: Linux Framebuffer drivers for small TFT LCD display modules), but all I get is these same black bars, mentioned here black bars on new esplora tft screen - Displays - Arduino Forum and here http://enduringbeta.com/2014/04/08/arduino-esplora-tft-screen-horizontal-bars-fix/.
It seems that the init sequence of the display has changed in comparison to the older model of the screen (LCD Modules · notro/fbtft Wiki · GitHub). Is there something else new/changed?
I have download the latest nightly of the Arduino for OSX and tried to extract the right init sequence values from there (file: Adafruit_ST7735.h) but with no avail.
These are the sequences i have tried:
Original init sequence:
modprobe fbtft_device name=adafruit18 init=-1,0x01,-2,50,-1,0x11,-2,100,-1,0x26,0x04,-1,0xb1,0x0b,0x14,-1,0xc0,0x08,0x00,-1,0xc1,0x05,-1,0xc5,0x41,0x30,-1,0xc7,0xc1,-1,0xec,0x1b,-1,0x3a,0x55,-2,100,-1,0x2a,0x00,0x00,0x00,0x7f,-1,0x2b,0x00,0x00,0x00,0x9f,-1,0x36,0xc8,-1,0xb7,0x00,-1,0xf2,0x00,-1,0xe0,0x28,0x24,0x22,0x31,0x2b,0x0e,0x53,0xa5,0x42,0x16,0x18,0x12,0x1a,0x14,0x03,-2,50,-1,0xe1,0x17,0x1b,0x1d,0x0e,0x14,0x11,0x2c,0xa5,0x3d,0x09,0x27,0x2d,0x25,0x2b,0x3c,-2,50,-3

Soooo.... does anyone have any idea what to do / try now? I have contacted the creator of the driver, but the help he provided sadly did not work. I would really appreciate any help!
