@jvmo said in External libraries and I2C via UIFLOW:

i2c1.write_u8(0x24, 0x00)

Thanks for the sample code. I am trying to use UIFlow to write a program running on M5Stack Core on the BTC Base with DHT12 sensor. I found it kept reading wrong data until the i2c1.write_u8(0x24, 0x00) sentence in your code inspired me.

Thank you for your solution! It works!

Thanks for the fix! However, I tried to compile the Hello example with errors in Arduino IDE. Please take a look at the logs below:

Arduino:1.8.4 (Mac OS X), 开发板："M5Stack-Core-ESP32, 80MHz, 921600, None"

...

collect2: error: ld returned 1 exit status
exit status 1
为开发板 M5Stack-Core-ESP32 编译时出错。

Hi，今天尝试在Arduino IDE中添加这个包索引文件，结果得到404错误，请尽快修复一下，谢谢！
