本来购买 ESP-Prog 调试 ESP32,发现无论如何 Ubuntu 22.04 都无法发现该设备(不知道是硬件问题还是驱动问题)(2024-02-13更新,是micro usb线的问题。有些micro usb线其实只有电源线,数据线不生效)。在网上看到一篇文章,可以利用树莓派进行 Jtag 调试。链接如下:ESP32 JTAG Debugging using Raspberry Pi。
mqttc.loop() #保持连接mqttc.connect()中的第三个参数是60,所以60s内要loop一下或者发布一条消息 (4)最后将时间和粉丝量发送给ESP32就行了,总代码如下: import json import time import requests import paho.mqtt.client as mqtt HOST="192.168.xxx.xxx" #改成你的树莓派ip ...
you need to move some zero-ohm links to route the USB port to the internal USB-serial-JTAG pins first, specifically R1 and R4 should be moved to R1 and R3. If these are too tiny for you, you can also take an USB cord, cut it in two, and connect the wires to +5V, GPIO18, ...
