ILI9341 display driver for the STM32F4 microcontroller

This repository contains a display driver for the STM32F4 microcontroller. The ILI9341 should be connected to the STM32F4 in 16-bit parallel mode.

Because the 16-bit parallel mode is used in combination with the MCU's FSMC, the data transfer to the display is very fast.

The driver only supports 16-bit (RGB565) colors.

Usage

The driver offers three functions for display memory access. Include stm32_ili9341p16_display.h to use the driver.

gd_display_init() should be called before any other display operations.

gd_display_fill(...) fills a rectangle on the display with a single color.

gd_display_bitmap(...) transfers data from the memory to the display.

LVGL wrapper

This driver can be used with the LittleV Graphics Library. This is a library to build GUI's.

To use this driver with LVGL, enable double buffering in LVGL with #define LV_VDB_DOUBLE 1 in lv_conf.h.

disp_fill is not implemented yet.

Dependencies

This driver requires the following libraries:

• ThrowTheSwitch's CException
• STM32F4 HAL
• CMSIS
