微控制器應用實驗室: STM32 HAL|| 16 bit parallel LCD-TFT driver using FSMC interface for LVGL || DMA

本文章介紹如何移植LVGL graphic library 到STM32上，另外說明有關LCD-TFT的driver使用STM32F4xx 的FSMC介面，STM32透過FSMC external memory access的方式驅動LCD-TFT。

一、使用硬體：

LCD-TFT

開發版STM32_F4VE

二、STM32F4xx Bus matrix:

CPU or DMA透過Bus Matrix可直接存取FSMC。

三、STM407xx memory map:

使用FSMC bank1 其範圍為0x6000 0000~0x6fff ffff。

四、 FSMC write waveform and LCD-TFT write cycle sequence 的時序圖。

LCD-TFT D/CX: Low時為command, High 實為GRAM data or commana的parameter data。相對於FSMC_A[25:0]的某一個address pin。

五、LCD-TFT Command&DATA address

本文章專案的FSMC設定如下圖：

LCD register select使用A18, 16 bits Data。因此A18為low時Address 為0x6000 0000代表command(D/CX low),。當A18為high 時Address 為0x6008 0000代表Data。

A[18]=HADDR[19]

六、移植LVGL library到STM32上：

copy lvgl中的scr資料夾與lvgl.h和lv_conf.h(由lv_conf_template.h更改檔名)檔案到專案中，並將檔案加到include paths中。
設定定期呼叫lv_tick_inc(x)的timer，本專案設定為5ms。
在main loop:定期呼叫lv_timer_handler()。
呼叫lv_init()並設定display與input device的driver。

詳細程式碼附於文末。
