In addition, when configuring the GPIO interrupt, I also set an IRQ handler function. In that handler, I check the state of the mentioned GPIO, and if it's LOW, I change both the interrupt and wakeup type to "GPIO_INTR_HIGH_LEVEL". Additionally, when the state of the GPIO is LOW,...

EN在从ccs811空气传感器寄存器读取数据时，我遇到了一些问题，例如，我想从css811_Programming_Guide重新创建一个示例，该示例是从下面介绍的硬件ID寄存器中读取的：对于esp32的玩法，基本上定位都是做上层应用，乐鑫官方提供的ESP-IDF物联网开发框架已经十分的完善，做上层应用按照这套框架进行开发，完全不必了解底层的...

You define a structurecolor_twhich specifies the red, green and blue component of a color. To show a color, you callsetColor()function. Inside this function, you set and update duty cycle for each LEDC channel based on the value of the red, green or blue component, for example, thered...
