3.2.2 LCD
The LCD available on the Adafruit 1.8" TFT shield uses 4-wire SPI to communicate with the
STM32F3 chip (Digital I/O pins 13, 11, 10 and 8) and has its own pixel-addressable frame
buffer to display text, shapes, lines, pixels, etc.
The SPI peripheral is configured within the stm32f3xx_nucleo.c/.h driver which contains
also the SPI bus link mechanism and IO operations.
The LCD is controlled by a dedicated BSP LCD driver stm32_adafruit_lcd.c/.h which uses
the st7735 component that exports in a generic way the LCD IO operations needed for its
process.
3.2.3 MicroSD
The microSD slot available on the Adafruit 1.8" TFT shield uses 4-wire SPI to communicate
with the STM32F3 chip (Digital I/O pins 13, 12, 11 and 4).
The SPI peripheral is configured within the stm32f3xx_nucleo.c/.h driver which contains
also the SPI bus link mechanism and IO operations.
The microSD is controlled by a dedicated BSP SD driver stm32_adafruit_sd.c/.h which
exports in a generic way the SD IO operations needed for its process.
