STM32 library for displays that are based on ST7735 controller.

Repository includes library and project files, library is device independent and uses one SPI module and 3 GPIOs to control:

• Reset line
• CS line
• DC line

Project is built for STM32F103RE with the following settings:

• SPI1 for communication (only MOSI ans SCK needed - PB5 for MOSI signal, PB3 for SCK)
• PB7 (Reset)
• PC11 (CS)
• PB6 (DC)

Software tools:

• IDE: IAR Embedded Workbench
• STM32CubeMx
• HAL Driver

Despite the fact that HAL driver is used SPI part is written with manual registers handling because it significantly increases LCD rendering speed. A detailed description is available on my site - STM32 ST7735 library.
