Re: Help program

So, I think here are tasks for you to make your project run: 1. If you are going to Arduino(which is a good choice for new beginner), you need to run Arduino on your esp first. https://github.com/espressif/arduino-esp32#installation-instructions https://www.arduino.cc/en/Main/FAQ 2. To control the m...

Re: I2C over DMA

In current version, we are still using interrupt to handle sending/receiving data.

Re: Inverting PWM signal on RGB Light

I think the best and easiest way to do that is to invert the GPIO output signal in esp32. Refer to func_out_sel_cfg register in components/soc/esp32/include/soc/gpio_struct.h. For example, if you want to invert GPIO18, you can use the following code to do that, after initializing light driver. GPIO....

Re: 請問一下以 Sample code 為框架的一些開發觀念問題!!

這些引用,應該找一下宣告的檔案再 include 進來就可解決
問題是,這樣的開發方式是正確的嗎???
其实,idf中所有模块的功能都是以 component 的形式提供,需要使用某个功能,必须要include对应的头文件,这个对于c语言开发来说都是这样。对于使用来说,也有的开发者会习惯通过IDE来配置路径。
esp-idf 所有相关的文档都可以在这里查看:
