1.11.2. 编程学习

打开main.py文件开始编写代码:

导入库文件:

import lcd_show
import font
from lcd_show import *
from font import *
import pyb
from pyb import Pin
import time
import utime
from random import randint
import framebuf

之后开始初始化引脚，代码为：

usrspi = USR_SPI(scl=Pin('X6',Pin.OUT_PP), sda=Pin('X7', Pin.OUT),dc=Pin('X8', Pin.OUT))
disp = DISPLAY(usrspi,cs=Pin('X5', Pin.OUT),res=Pin('X4', Pin.OUT),led_en=Pin('X3', Pin.OUT))
disp.clr(disp.WHITE)

设置完毕后，即可编写函数实现日历效果的效果，代码如下：
