Micropython玩转ESP32P4：开启屏幕显示
本帖最后由 PY学习笔记 于 2025-8-19 17:40 编辑近期，DFRobot已经推出了全新开发板 FireBeetle 2 ESP32-P4。这块开发板搭载了 ESP32-P4 主控，虽未集成 Wi-Fi 与蓝牙，但凭借强劲性能，依然令人眼前一亮。很荣幸能体验这块开发板！1.开发板介绍FireBeetle 2 ESP32-P4有很多种外设:
[*]Type-C USB CDC：Type-C USB烧录、调试接口
[*]IO3/LED：板载LED引脚
[*]Power LED：主板电源指示灯
[*]RST：复位按键
[*]IO35/BOOT：IO引脚/BOOT按键
[*]MIC: MEMS PDM麦克风
[*]HIGH-SPEED USB OTG 2.0: Type-C高速USB OTG 2.0
[*]ESP32-P4：ESP32-P4芯片
[*]MIPI-DSI: 两通道MIPI-DSI屏幕（兼容树莓派4B DSI屏幕线序）
[*]MIPI-CSI: 两通道MIPI-DSI屏幕（兼容树莓派4B CSI摄像头线序）
[*]TF Card: TF卡插槽
[*]16MB FLASH: 16MB Flash存储
[*]ESP32-C6：ESP32-C6-MINI-1模组，通过SDIO与ESP32-P4连接，用于扩展WiFi、蓝牙
2.添加屏幕驱动依旧放在GitHub上：https://github.com/Vincent1-python/esp32p4-micropython-dfrobot-rpi-dsi-driver按照《Micropython玩转ESP32P4：绑定AI相关模块》再次编译下载即可3.正式体验这里先做一个单显示测试：from lcd import *
from machine import Pin
from machine import I2C
i2c = I2C(0,scl=Pin(8), sda=Pin(7))
init()
i2c.writeto_mem(0x45, 0x86, b'\xff')
# 初始化LCD
clear(WHITE)
string(10, 0, 500, 32, 32, "DFRobot ESP32-P4 MIPI LCD TEST", RED)
string(10, 40, 240, 24, 24, "PYSN", BLUE)
string(10, 80, 240, 24, 24, "DFRobot", BRRED)
触摸测试：from machine import Pin
from machine import I2C
import time,lcd
from ft5x06 import FT5x06
# 触摸点颜色和状态
POINT_COLOR_TBL =
last_points = [ for _ in range(5)]# 5个触摸点的最后位置
def lcd_draw_bline(x1, y1, x2, y2, size, color):
"""优化后的带宽度直线绘制函数"""
dx = abs(x2 - x1)
dy = abs(y2 - y1)
sx = 1 if x1 < x2 else -1
sy = 1 if y1 < y2 else -1
err = dx - dy
while True:
lcd.fill_circle(x1, y1, size, color)
if x1 == x2 and y1 == y2:
break
e2 = 2 * err
if e2 > -dy:
err -= dy
x1 += sx
if e2 < dx:
err += dx
y1 += sy
if __name__ == "__main__":
lcd.init()
i2c = I2C(0,scl=Pin(8), sda=Pin(7))
t = FT5x06(i2c)
i2c.writeto_mem(0x45, 0x86, b'\xff')
lcd.clear(lcd.WHITE)
while True:
touch = t.get_positions()
if touch:
for i, point in enumerate(touch[:5]):
# 计算当前触摸点坐标
curr_x = 800-point
curr_y = 480-point
# 绘制从上次位置到当前位置的线
if last_points != :
lcd_draw_bline(last_points, last_points,
curr_x, curr_y, 4, POINT_COLOR_TBL)
# 更新最后位置
last_points =
else:
# 无触摸时重置所有点
for i in range(5):
last_points =
