需要什么

**
一块lcd ，市面上大多数为spi ，i2c驱动的lcd，我这块是比赛剩下的模拟8080端口驱动。区别不大，仅需改动发送数据的函数
一个摄像头，我这里使用的是某宝17块钱买来的ovxx具体多少忘了，树莓派自带驱动。
opencv，仅用来把摄像头传来的图片转为lcd可显示的bgr565格式，也可不使用自行编写转化函数（百度一下马上知道）。
picamera，树莓派自带的摄像头驱动库，import即可使用

端口定义

驱动芯片为ST7735，8080并口发送数据
RST（复位线）
DB0~DB7(数据线)
RS（数据/指令选择线，1:数据读写,0:命令读写
CS（片选信号线）

下面是最终的成品，效率有待提升，可以看见屏幕刷新的条纹

下面上代码

底层代码

端口及一些参数定义

import RPi.GPIO as GPIO
import time
# 引脚定义
LCD__CS = 5
LCD_RST = 6
LCD_WR = 13
LCD_RS = 19
LCD_RD = 26
LCD_SIGN = [LCD__CS, LCD_RST, LCD_WR, LCD_RS, LCD_RD]
LCD_D0 = 21
LCD_D1 = 20
LCD_D2 = 16
LCD_D3 = 12
LCD_D4 = 7
LCD_D5 = 8
LCD_D6 = 25
LCD_D7 = 24
LCD_DATA = [LCD_D7, LCD_D6, LCD_D5, LCD_D4, LCD_D3, LCD_D2, LCD_D1, LCD_D0]
#液晶大小
X_ORIGIN = 0
Y_ORIGIN = 0
X_MAX_PIXEL = 128
Y_MAX_PIXEL = 128#存储颜色
COLORLIST = []
# 颜色代码
RED = 0xf800
GREEN = 0x07e0
BLUE = 0x001f
WHITE = 0xffff
BLACK = 0x0000
YELLOW = 0xFFE0
GRAY0 = 0xEF7D
GRAY1 = 0x8410
GRAY2 = 0x4208

gpio端口的初始化，使用BCM模式

# gpio初始化
def gpio_init():GPIO.setwarnings(False)GPIO.setmode(GPIO.BCM)GPIO.setup(LCD_WR, GPIO.OUT, initial=GPIO.LOW)GPIO.setup(LCD_RD, GPIO.OUT, initial=GPIO.HIGH)GPIO.setup(LCD__CS, GPIO.OUT, initial=GPIO.HIGH)GPIO.setup(LCD_RS, GPIO.OUT, initial=GPIO.LOW)GPIO.setup(LCD_RST, GPIO.OUT, initial=GPIO.LOW)GPIO.setup(LCD_DATA, GPIO.OUT, initial=GPIO.LOW)  # datatime.sleep(0.1)

为提高效率提前对颜色代码进行转化，如COLORLIST[1]=[False,False,False,False,False,False,False,True]

def bit_to_list(t):s = [False for i in range(8)]i = -1while t != 0:if t % 2 == 1:s[i] = Trueelse:s[i] = Falset = t >> 1i -= 1return s
# 提前生成颜色列表
def generate_colorlist():for i in range(0xff + 1):COLORLIST.append(bit_to_list(i))

数据和指令发送函数

# 发送数据
def send(bits):GPIO.output(LCD_DATA, COLORLIST[bits])
# 发送8位数据
def Lcd_WriteData(data):GPIO.output(LCD__CS, False)GPIO.output(LCD_RS, True)send(data)GPIO.output(LCD__CS, True)
# 发送8位命令
def Lcd_WriteIndex(cmd):GPIO.output(LCD__CS, False)GPIO.output(LCD_RS, False)send(cmd)GPIO.output(LCD__CS, True)
# 发送16位数据,颜色
def Lcd_WriteData_16(cmd):GPIO.output(LCD__CS, False)GPIO.output(LCD_RS, True)send(cmd >> 8)GPIO.output(LCD__CS, True)GPIO.output(LCD__CS, False)send(cmd % 256)GPIO.output(LCD__CS, True)
# 发送16位数据,少两步
def Lcd_WriteColor_16(cmd1, cmd2):GPIO.output(LCD__CS, False)GPIO.output(LCD_RS, True)send(cmd1)GPIO.output(LCD__CS, True)GPIO.output(LCD__CS, False)send(cmd2)GPIO.output(LCD__CS, True)

液晶初始化，主要设置液晶的显示模式，copy别人的，具体设置可参考芯片手册

# 复位
def reset():GPIO.output(LCD_RST, False)time.sleep(0.1)GPIO.output(LCD_RST, True)time.sleep(0.1)
# 初始化

树莓派驱动1.44寸TFT液晶并实时显示摄像头图像

需要什么

端口定义

底层代码

端口及一些参数定义

gpio端口的初始化，使用BCM模式

为提高效率提前对颜色代码进行转化，如COLORLIST[1]=[False,False,False,False,False,False,False,True]

数据和指令发送函数

液晶初始化，主要设置液晶的显示模式，copy别人的，具体设置可参考芯片手册

开窗，每次想刷新屏幕必须在要刷新的位置开窗。

显示代码能驱动屏幕剩下的都好办了

字符显示所需要的ASII表

最后当然是调用这些函数来达到开头的显示效果，这里使用了opencv来把摄像头采集的24位全彩图转化为液晶可显示的16位真彩图。当然也可以不使用opencv，自己进行转化。`
