Introduction

This is the library for the Adafruit RA8875 Driver board for TFT displays ---------------> http://www.adafruit.com/products/1590 The RA8875 is a TFT driver for up to 800x480 dotclock'd displays It is tested to work with displays in the Adafruit shop. Other displays may need timing adjustments and are not guanteed to work.

Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!

Function Documentation

__attribute__()

__attribute__

(

(weak)

)

Frequency of the clock feeding an SPI peripheral (before the baud prescaler). Weak: override it in your project if the default does not match your MCU family/clock tree.

Note

Default: APB2 for SPI1/4/5/6, APB1 otherwise (STM32F4/F7/L4/G4...); STM32H7 asks the RCC for the SPI kernel clock.
