Nokia5110_LCD

STM32 Low Layer(LL) library. At the heart of the module is a powerful single-chip low power CMOS LCD driver controller from Philips – PCD8544. The chip is designed to drive a graphic display of 84×48 pixels. It interfaces to microcontrollers through a serial bus interface SPI.

Features

• Small code footprint
• Interrupt and Polling LCD SPI versions
• Lot of predefined fonts
• Display printf function
• No HAL dependencies

Project configuration

1. Start project with STM32CubeMX:
   • SPI configuration
   • GPIO configuration
2. Select: Project Manager -> Advanced Settings -> SPI -> LL
3. Generate Code
4. Add sources to project:

• Polling LCD SPI

add_subdirectory(${STM32_CORE_SOURCE_DIR}/SPI/Polling)  # add SPI dependency

include_directories(${includes}
        ${NOKIA5110_LCD_DIRECTORY})   # source directories

file(GLOB_RECURSE SOURCES ${sources}
        ${NOKIA5110_LCD_SOURCES})    # source files

• Interrupt based LCD

add_subdirectory(${STM32_CORE_SOURCE_DIR}/SPI/IT)  # add for interrupt version

include_directories(${includes}
        ${NOKIA5110_LCD_IT_DIRECTORY})   # source directories

file(GLOB_RECURSE SOURCES ${sources}
        ${NOKIA5110_LCD_IT_SOURCES})    # source files

3. Then Build -> Clean -> Rebuild Project
