In addition, hardware improvements have caused the kernel to start much faster than before; the messages flash by so quickly, it can be difficult to see what is happening. 传统的Unix系统在启动时会产生许多诊断消息,告诉你有关启动过
Before we get into that let’s make sure that our ESP32 module has this external PSRAM and that it is addressable from our code. The ESP32/Arduino platform exposes a couple of methods to find out how much RAM you have in total and how much you can use. #include <Arduino.h> void s...
There is one more thing, the ESP32 takes 7 bit address for the I2C device. All the functions, which are included in the library of ESP32 will shift this address to the left by 1 bit, 0x27<<1, and the LSB here will be responsible forread(1)/ write(0)operation. If you plan to ...

Hi, I have a question regarding the 30-pin DIP Arduino-like ESP32 device. I want it to operate together with another high-speed device, and I would like the two devices to operate synchronously, so I can keep them generally in step with one another. The other device (a "UPduino" ...
Luckily, we need not do much to get this value. There are readymade functions available, that give out the value in bytes. Let’s have a look at them: Overall Free Memory If you want to get overall free memory available, use the function esp_get_free_heap_size(). An example usage ...
This concludes my introduction to VS Code and ESP-IDF. In my opinion, they make for a powerful combination of development tools, and, together, provide a comfortable and simplified development environment for ESP32 applications, regardless of the OS you're using. Using VS Code with ESP-IDF ...

Now as a project enclosure, I am using a Styrofoam disk that has been cut out from a larger sheet. This makes for a great insulator. Another much smaller disk is stuck on top but a bit to the side. This is for wrapping the extra length of wires so they are not dangling all over ...
Answers checklist. I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there. I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there. I have s...
