通过 STM32 的 FSMC 接口来控制 TFTLCD 的显示。

TFTLCD简介

TFT-LCD 即薄膜晶体管液晶显示器。其英文全称为：Thin Film Transistor-Liquid Crystal Display。TFT-LCD 与无源 TN-LCD、STN-LCD 的简单矩阵不同，它在液晶显示屏的每一个象素上都设置有一个薄膜晶体管（TFT），可有效地克服非选通时的串扰，使显示液晶屏的静态特性与扫描线数无关，因此大大提高了图像质量。TFT-LCD 也被叫做真彩液晶显示器。

FSMC简介

STM32的FSMC外设简介
STM32 FSMC/FMC原理保姆级讲解(一)
FSMC，即灵活的静态存储控制器，能够与同步或异步存储器和 16 位 PC 存储器卡连接， STM32 的 FSMC 接口支持包括SRAM、NAND FLASH、NOR FLASH 和PSRAM 等存储器。
STM32自带的FSMC功能，就是专门为这类存储器设计的，在STM32上，有一些引脚被专门设计成地址线，还有一些被专门设计成数据线，还有一些被设计成控制线，然后这些地址线和数据线对应着固定的地址，只要外部的DRAM等存储器将对应的数据线连接到STM32这些对应的引脚上，引脚功能设置为复用模式，通过配置FSMC ，你可以直接给上面那个固定的地址赋值，其他操作STM32都会自动给你完成，就可以把数据存储到SRAM中。
FSMC 的框图如图18.1.2.1 所示：

从上图我们可以看出，STM32 的FSMC 将外部设备分为 3 类：NOR/PSRAM 设备、NAND设备、PC 卡设备。他们共用地址数据总线等信号，他们具有不同的 CS 以区分不同的设备，比如本章我们用到的TFTLCD 就是用的FSMC_NE4 做片选，其实就是将TFTLCD 当成SRAM 来控制。

外部SRAM 的控制一般有：地址线（如A0 ~ A18）、数据线（如D0~ D15）、写信号（WE）、读信号（OE）、片选信号（CS），如果SRAM 支持字节控制，那么还有UB/LB 信号。而TFTLCD的信号包括：RS、D0~ D15、WR、RD、CS、RST 和 BL 等，其中真正在操作LCD 的时候需要用到的就只有：RS、D0~D15、WR、RD 和CS。其操作时序和 SRAM的控制完全类似，唯一不同就是 TFTLCD 有RS 信号，但是没有地址信号。
TFTLCD 通过 RS 信号来决定传送的数据是数据还是命令，本质上可以理解为一个地址信号，比如我们把RS 接在A0 上面，那么当FSMC 控制器写地址0 的时候，会使得A0 变为0，对TFTLCD 来说，就是写命令。而 FSMC 写地址 1 的时候，A0 将会变为1，对 TFTLCD 来说，就是写数据了。这样，就把数据和命令区分开了，他们其实就是对应 SRAM 操作的两个连续地址。当然RS 也可以接在其他地址线上，精英STM32 开发板是把RS 连接在A10 上面的。

对于NOR FLASH 控制器，主要是通过FSMC_BCRx、FSMC_BTRx 和 FSMC_BWTRx 寄存器设置（其中 x=1~4，对应 4 个区）。通过这 3 个寄存器，可以设置 FSMC 访问外部存储器的时序参数，拓宽了可选用的外部存储器的速度范围。FSMC 的NOR FLASH 控制器支持同步和异步突发两种访问方式。选用同步突发访问方式时，FSMC 将 HCLK(系统时钟)分频后，发送给外部存储器作为同步时钟信号 FSMC_CLK。此时需要的设置的时间参数有 2 个：
1，HCLK 与 FSMC_CLK 的分频系数(CLKDIV)，可以为2～16 分频；
2，同步突发访问中获得第 1 个数据所需要的等待延迟(DATLAT）
对于异步突发访问方式，FSMC 主要设置 3 个时间参数：地址建立时间(ADDSET)、数据建立时间(DATAST)和地址保持时间(ADDHLD)。FSMC 综合了SRAM／ROM、PSRAM 和NOR Flash 产品的信号特点，定义了 4 种不同的异步时序模型。

这里，我们使用存储块1，STM32 的 FSMC 存储块1（Bank1）被分为 4 个区，每个区管理64M 字节空间，每个区都有独立的寄存器对所连接的存储器进行配置。Bank1 的 256M 字节空间由 28 根地址线（HADDR[27:0]）寻址。其中 HADDR[25:0]来自外部存储器地址FSMC_A[25:0]，而HADDR[26:27]对4 个区进行寻址。
当Bank1 接的是 16 位宽度存储器的时候：HADDR[25:1]→ FSMC_A[24:0]。
当Bank1 接的是 8 位宽度存储器的时候：HADDR[25:0]→ FSMC_A[25:0]。
不论外部接8 位/16 位宽设备，FSMC_A[0]永远接在外部设备地址A[0]。

FSMC寄存器

SRAM/NOR 闪存片选控制寄存器 FSMC_BCRx（x=1~4）

EXTMOD：扩展模式使能位，也就是是否允许读写不同的时序，很明显，我们本章需要读写不同的时序，故该位需要设置为 1。
WREN：写使能位。我们需要向 TFTLCD 写数据，故该位必须设置为 1。
MWID[1:0]：存储器数据总线宽度。00，表示 8 位数据模式；01 表示 16 位数据模式；10和11 保留。我们的TFTLCD 是 16 位数据线，所以设置WMID[1:0]=01。
MTYP[1:0]：存储器类型。00 表示SRAM、ROM；01 表示PSRAM；10 表示NOR FLASH;11保留。前面提到，我们把TFTLCD 当成SRAM 用，所以需要设置MTYP[1:0]=00。
MBKEN：存储块使能位。这个容易理解，我们需要用到该存储块控制 TFTLCD，当然要使能这个存储块了。

SRAM/NOR 闪存片选时序寄存器 FSMC_BTRx（x=1~4）

这个寄存器包含了每个存储器块的控制信息，可以用于 SRAM、ROM 和NOR 闪存存储器。如果 FSMC_BCRx 寄存器中设置了 EXTMOD 位，则有两个时序寄存器分别对应读(本寄存器)和写操作(FSMC_BWTRx 寄存器)。因为我们要求读写分开时序控制，所以 EXTMOD 是使能了的，也就是本寄存器是读操作时序寄存器，控制读操作的相关时序。

ACCMOD[1:0]：访问模式。00 表示访问模式 A；01 表示访问模式B；10 表示访问模式C；11 表示访问模式D，本章我们用到模式A，故设置为 00。
DATAST[7:0]：数据保持时间。0 为保留设置，其他设置则代表保持时间为: DATAST 个HCLK 时钟周期，最大为255 个HCLK 周期。对 ILI9341 来说，其实就是RD 低电平持续时间，一般为355ns。而一个HCLK 时钟周期为 13.8ns 左右（1/72Mhz），为了兼容其他屏，我们这里设置DATAST 为15，也就是16 个HCLK 周期，时间大约是234ns（未计算数据存储的2 个HCLK时间，对9341 来说超频了，但是实际上是可以正常使用的）。
ADDSET[3:0]：地址建立时间。其建立时间为：ADDSET 个HCLK 周期，最大为 15 个HCLK周期。对 ILI9341 来说，这里相当于 RD 高电平持续时间，为 90ns，本来这里我们应该设置和DATAST 一样，但是由于 STM32F103 FSMC 的性能问题，就算设置ADDSET 为0，RD 的高电平持续时间也达到了 190ns 以上，所有，我们这里可以设置 ADDSET 为较小的值，本章我们设置ADDSET 为1，即 2 个HCLK 周期，实际RD 高电平大于200ns。

SRAM/NOR 闪写时序寄存器 FSMC_BWTRx（x=1~4）

该寄存器在本章用作写操作时序控制寄存器，需要用到的设置同样是：ACCMOD、DATAST和ADDSET 这三个设置。这三个设置的方法同 FSMC_BTRx 一模一样，只是这里对应的是写操作的时序，ACCMOD 设置同FSMC_BTRx 一模一样，同样是选择模式A，另外DATAST 和ADDSET 则对应低电平和高电平持续时间，对ILI9341 来说，这两个时间只需要 15ns 就够了，比读操作快得多。所以我们这里设置 DATAST 为 3，即 4 个HCLK 周期，时间约为 55ns（因为9320 等控制器，这个时间要求比较长，要50ns）。然后 ADDSET（也存在性能问题）设置为 0，即1 个HCLK 周期，实际WR 高电平时间大于 100ns。

FSMC_BCRx 和 FSMC_BTRx，组合成**BTCR[8]**寄存器组，他们的对应关系如下：
BTCR[0]对应FSMC_BCR1，
BTCR[1]对应 FSMC_BTR1
BTCR[2]对应FSMC_BCR2，
BTCR[3]对应 FSMC_BTR2，
BTCR[4]对应FSMC_BCR3，
BTCR[5]对应 FSMC_BTR3，
BTCR[6]对应FSMC_BCR4，
BTCR[7]对应 FSMC_BTR4

FSMC_BWTRx 则组合成BWTR[7]，他们的对应关系如下：
BWTR[0]对应 FSMC_BWTR1，
BWTR[2]对应 FSMC_BWTR2，
BWTR[4]对应 FSMC_BWTR3，
BWTR[6]对应 FSMC_BWTR4，
BWTR[1]、BWTR[3]，BWTR[5]保留，没有用到。
