esp32与 micropython 编写IP修改界面

1. 导入必要的库

import network
import time
import ujson
from machine import Pin
from machine import SoftSPI
from ili934xnew import ILI9341

2. 设置SPI总线和ILI9341显示屏

spi = SoftSPI(
    baudrate=40000000,
    polarity=1,
    phase=0,
    sck=Pin(18),
    mosi=Pin(23),
    miso=Pin(19))

lcd = ILI9341(
    spi,
    cs=Pin(5),
    dc=Pin(27),
    rst=Pin(33),
    width=320,
    height=240,
    rotation=0)

3. 设置WiFi

sta_if = network.WLAN(network.STA_IF)
sta_if.active(True)

4. 定义IP修改界面

def ip_setting():
    ip = sta_if.ifconfig()[0]
    subnet = sta_if.ifconfig()[1]
    gateway = sta_if.ifconfig()[2]
    dns = sta_if.ifconfig()[3]

    lcd.fill(ILI9341.BLACK)
    lcd.text("IP Setting", 50, 50, ILI9341.WHITE)

    lcd.text("IP Address:", 20, 80, ILI9341.WHITE)
    ip_input = ""
    ip_cursor = 0
    while True:
        lcd.fill_rect(20, 100, 280, 30, ILI9341.WHITE)
        lcd.text(ip_input, 20, 100, ILI9341.BLACK)
        lcd.rect(20 + ip_cursor*10, 100, 10, 30, ILI9341.RED)
        if len(ip_input) >= 15:
            break
        if lcd.touch_in_rect(20, 140, 80, 40):
            break
        if lcd.touch_in_rect(20, 180, 80, 40):
            ip_input = ip_input[:-1]
            ip_cursor = max(0, ip_cursor-1)
        if lcd.touch_in_rect(240, 140, 60, 40):
            break
        if lcd.touch_in_rect(240, 180, 60, 40):
            ip_input += "."
            ip_cursor += 1
        for i in range(10):
            if lcd.touch_in_rect(110+i*20, 140, 20, 40):
                ip_input += str(i)
                ip_cursor += 1
    ip = ip_input

    lcd.text("Subnet Mask:", 20, 150, ILI9341.WHITE)
    subnet_input = ""
    subnet_cursor = 0
    while True:
        lcd.fill_rect(20, 170, 280, 30, ILI9341.WHITE)
        lcd.text(subnet_input, 20, 170, ILI9341.BLACK)
        lcd.rect(20 + subnet_cursor*10, 170, 10, 30, ILI9341.RED)
        if len(subnet_input) >= 15:
            break
        if lcd.touch_in_rect(20, 210, 80, 40):
            break

            subnet_input = subnet_input[:-1]
            subnet_cursor = max(0, subnet_cursor-1)
        if lcd.touch_in_rect(240, 210, 60, 40):
            break
        if lcd.touch_in_rect(240, 250, 60, 40):
            subnet_input += "."
            subnet_cursor += 1
        for i in range(10):
            if lcd.touch_in_rect(110+i*20, 210, 20, 40):
                subnet_input += str(i)
                subnet_cursor += 1
    subnet = subnet_input

    lcd.text("Gateway:", 20, 260, ILI9341.WHITE)
    gateway_input = ""
    gateway_cursor = 0
    while True:
        lcd.fill_rect(20, 280, 280, 30, ILI9341.WHITE)
        lcd.text(gateway_input, 20, 280, ILI9341.BLACK)
        lcd.rect(20 + gateway_cursor*10, 280, 10, 30, ILI9341.RED)
        if len(gateway_input) >= 15:
            break
        if lcd.touch_in_rect(20, 320, 80, 40):
            break
        if lcd.touch_in_rect(20, 360, 80, 40):
            gateway_input = gateway_input[:-1]
            gateway_cursor = max(0, gateway_cursor-1)
        if lcd.touch_in_rect(240, 320, 60, 40):
            break
        if lcd.touch_in_rect(240, 360, 60, 40):
            gateway_input += "."
            gateway_cursor += 1
        for i in range(10):
            if lcd.touch_in_rect(110+i*20, 320, 20, 40):
                gateway_input += str(i)
                gateway_cursor += 1
    gateway = gateway_input

    lcd.text("DNS Server:", 20, 370, ILI9341.WHITE)
    dns_input = ""
    dns_cursor = 0
    while True:
        lcd.fill_rect(20, 390, 280, 30, ILI9341.WHITE)
        lcd.text(dns_input, 20, 390, ILI9341.BLACK)
        lcd.rect(20 + dns_cursor*10, 390, 10, 30, ILI9341.RED)
        if len(dns_input) >= 15:
            break
        if lcd.touch_in_rect(20, 430, 80, 40):
            break
        if lcd.touch_in_rect(20, 470, 80, 40):
            dns_input = dns_input[:-1]
            dns_cursor = max(0, dns_cursor-1)
        if lcd.touch_in_rect(240, 430, 60, 40):
            break
        if lcd.touch_in_rect(240, 470, 60, 40):
            dns_input += "."
            dns_cursor += 1
        for i in range(10):

                dns_input += str(i)
                dns_cursor += 1
    dns = dns_input

    sta_if.ifconfig((ip, subnet, gateway, dns))

    lcd.fill(ILI9341.BLACK)
    lcd.text("IP Setting", 50, 50, ILI9341.WHITE)
    lcd.text("IP Address:", 20, 80, ILI9341.WHITE)
    lcd.text(ip, 120, 80, ILI9341.WHITE)

    lcd.text("DNS Server:", 20, 170, ILI9341.WHITE)
    lcd.text(dns, 120, 170, ILI9341.WHITE)
    time.sleep(2)

5. 在主程序中调用IP修改界面

while True:
    if lcd.touch_in_rect(10, 10, 60, 40):
        ip_setting()
    time.sleep(0.1)
