First of all to ensure that the computer has downloaded the Git client, no self- https://git-scm.com/downloadSTEP1: Get the Build ToolchainWindows does not have a built-in "make" environment, so you will need a GNU-compatible environment to install the toolchain. We use the MSYS2 Environment to provide this. You don't have to use this environment all the time, you can program with front-end software such as Eclipse or Arduio, but the toolchain is actually running in the background. The quick

This post is suitable for entry-level personnel, but at the same time welcome new and old readers to criticize.A treasure bought a esp32, there is a ESP32 development guide book.And then the environment is built. The above is written mainly on Linux, I built a half-day on my orange Pi PC Development Board, there are some areas behind the problem, not ready. After the time to deal with the process, after all

This project has been managed to GitHub, the specific path is Https://github.com/tidyjiang8/esp32-projects/tree/master/sta In the previous blog "Let ESP32 connect to your WiFi hotspot", we have simply analyzed the WiFi workflow and briefly prompted the event scheduler/wifi state machine, which we will analyze in detail in this blog post. In ESP-IDF, the entire WiFi stack is a state machine that has a stat

Esp32's system initialization and startup process and design learning methods For esp32, only one app_main function exists in the development program. This function is the entrance of the user program. This is equivalent to the main function in the system where FreeRTOS is not called, but before app_main, the system has another initialization process, which can be roughly divided into the following three pr

This project has been managed to GitHub, the specific path is Https://github.com/tidyjiang8/esp32-projects/tree/master/sta Git plus--recursive Function Description: Connect ESP32 as an STA to a WiFi hotspot. "Quick Start" "Suppose" you have installed the ESP-IDF and toolchain. You already have a WiFi hotspot. "Step" uses the data cable to connect the board to your system, allowing the system to recognize y

0 Introduction CAD/CAE/CAM, Computer Aided Engineering/Computer Aided manufacturing, is a comprehensive application technology which integrates and penetrates computer and numerical computing, mechanical design and manufacturing technologies. It not only changed the way people design and manufacture products, gave full play to the creativity of designers, at the same time, it can greatly improve the management level and market competitiveness of ente

Recently when using ESP32 to drive an SPI device, the SPI device did not answer, strange when I used stm32 successfully driven the SPI device, how to transplant to ESP32 is not possible. When using Stm32 I use SPI mode3, i.e. cpol=1, Cpha=1, refer to the generic SPI mode definition: SPI four mode SPI phase (CPHA) and polarity (Cpol) can be 0 or 1 respectively, the corresponding 4 combinations constitute the

Cam block chain is recently seen on the GitHub open source project, because it is. NET written, more familiar, easy to see the source code to understand the operation of the block chain principle.

Play ESP32 (2): WiFi Code Implementation ESP32 as a wifi+ Bluetooth chip, the realization of WiFi is its most basic function, and in ESP32, the use of WiFi can be achieved STA, AP, Sta+ap three ways. STA Code Implementation First look at one of the simplest examples of implementing WiFi sta. #include "freertos/freertos.h" #include "freertos/task.h" #include "fre

Core Tip: I believe that flash Cam is a lot of people are looking forward to the Flash Image Capture tool, is a very good to do demo software. In advocating research-oriented learning and independent learning today, when teachers to students to teach a computer skills, can be made in advance to make good demo courseware to enable students to learn independently. Here, I recommend Flash Cam, a very good sof

In the previous article, I have already talked about downloading ESP-IDF using Linux's own tools, but in order to develop the system, we use eclipse to compile the IDF as a whole.First of allCd/esp32Run Eclipse and select workspace under/home/li/esp32/workspace/hello_worldUsing directivescd/esp32/esp-idf/examples/get-started/hello_world/ and Instructions Cp-r Hello_world/home/li/

effects from your photos. It is quite interesting to look at your "ghost" in your spare time. But now, if you are still playing with the photo, it will be out. VideoCopilot, which has made special effects for many blockbusters and games, has developed a new Demon Cam application. Through this application, you can also create special effects videos that are visually appealing like VideoCopilot. The most fascinating thing is that this application i

corresponding file. The conditions for flushing the buffer zone are as follows: 1) buffer Filling 2) The written characters include '\ n' 3) Call fflush to manually refresh the buffer 4) When scanf is called to read data from the buffer, it also refreshes the data in the buffer. Someone asked why I can print the program smoothly without adding '\ n', because your printf is not in a loop and won't involve any problems, because even after printf is executed, the content is only sent to the buffer
