Compiling but not working on AtTiny85

[Duico]

I'm running the Example.c file you provide, compiling it inside Arduino IDE.

My wiring: AtTiny85->1.8" TFT

• 0->SDA
• 1->AO
• 2->SCK
• 5->RESET
• GND->CS

Is it right to ground the CS pin? I used this display before but CS was connected to a data pin in that case.

According to SPI standard (wiki), CS (Chip Select) is pull-up when disabled and is pulled to ground whtn master wants to select the given device. So it is perfectly normal to connect CS to GND if you use only one SPI device. Your problem should be in something else.
