WCHlink Debugger for ARM/RISC-V, by WeAct Studio. ~ Steps to download firmware on CH582F (RISC-V) using WeAct WCHlink Debugger Related link: ~  gitee Wchlink (https://gitee.com/WeAct-TC/wchlink)

Its' CH582F BLE5.3 Core Board, by WeAct Studio. Related Link: ~ Product Page ~ Github WeActStudio.WCH-BLE-Core Remark in my start-up using CH582F BLE5.3 Core Board + WCHlink Debugger for ARM/RISC-V , by WeAct Studio. (on Windows 10) Install MounRiver & WCHISPTool (and driver) Download and install MounRiver Studio to build first Hello World. Firstly, I build a Hello World using MounRiver Studio and try to download to CH582F using ISP (In-System Programmer). At most beginning, I download and install  WCHISPTool_Setup.exe from Github , it's version 3.3. Suppose it will install WCHlink USB driver also. To put the CH582F in ISP mode, press and hold the BOOT button and connect to USB port. In my case, CH582F cannot be recognized. Then I download and re-install from WCH page (http://www.wch-ic.com/downloads/WCHISPTool_Setup_exe.html) . It's named  WCHISPStudio 3.4 now. Then it can be recognized, and everything get smooth. Whe

Last post show steps to display on 2.13" 250x122 3-color E-paper (SSD1680) with ESP32-DevKitC V4 using ZinggJM/GxEPD2 Library (in arduino-esp32 framework) . This video show using another library  Adafruit_EPD . It can be installed using Arduino IDE Library Manager. Connection Same as in previous post: e-paper ESP32 GPIO ------------------ 1 BUSY GP15 2 RES GP2 3 D/C GP0 4 CS GP5 5 SCL GP18 6 SDA GP23 7 GND GND 8 VCC 3V3 Library Search and install Arduino_EPD in Arduino IDE Library Manager.

Display on 2.13" 250x122 3-color E-paper (SSD1680) with ESP32-DevKitC V4 using ZinggJM/GxEPD2 Library (in arduino-esp32 framework). Visit WeAct Studio 2.13/2.9 Inch Epaper Module EPD in GitHub (https://github.com/WeActStudio/WeActStudio.EpaperModule) . It provide info and example code for WeAct Epaper Modules. We are going to use EpaperModuleTest_Arduino_ESP32 Example later, it use GxEPD2 library to control e-paper. Visit Github ZinggJM/GxEPD2 (https://github.com/ZinggJM/GxEPD2) . To download library in ZIP: Click on Code > Download ZIP Open Arduino IDE, to install download library: Sketch > Include Library > Add ZIP Library Select the downloaded ZIP file Connection To run the examples below, we follow the connection in WeAct Example: e-paper ESP32 GPIO ------------------ 1 BUSY GP15 2 RES GP2 3 D/C GP0 4 CS GP5 5 SCL GP18 6 SDA GP23 7 GND GND 8 VCC 3V3 Try WeAct Example Then copy  WeAct Example, EpaperModuleTest_Arduino_ESP32

This video show steps to install Rust (1.67.1) on Linux Mint 21.1 (over VirtualBox). To install Rust on Linux (or macOS), enter the command in Terminal: $ curl --proto '=https' --tlsv1.3 https://sh.rustup.rs -sSf | sh The command downloads a script and starts the installation of the rustup tool, which installs the latest stable version of Rust. ref: ~  https://doc.rust-lang.org/book/ch01-01-installation.html After Rust installed, you can follow the steps in the video to try your first Hello World using rustc, or using Cargo. rustc is fine for simple programs. But as your project grows, you’ll want to manage all the options and make it easy to share your code. Cargo will help you write real-world Rust programs. Cargo is Rust’s build system and package manager. Most Rustaceans use this tool to manage their Rust projects because Cargo handles a lot of tasks for you, such as building your code, downloading the libraries your code depends o
