This video show how to flash & run GPIO_Toggle example on WCH CH32V307V_EVT-R1 using MounRiver Studio, to blink LED and monitor USART. Prepare CH32V307EVT evaluation board manual and reference routines Visit: https://www.wch.cn/products/CH32V307.html to download CH32V307评估板说明及参考应用例程 (CH32V307EVT evaluation board manual and reference routines)： CH32V307EVT.ZIP Open GPIO_Toggle.wvproj with MounRiver Studio (under \CH32V307EVT\EVT\EXAM\GPIO\GPIO_Toggle folder), this example toggle PA0 and print something on USART. Connect USB to CH32V307V_EVT-R1: It's a built-in WCH-LinkE (same function as this one ) on CH32V307V_EVT-R1, used for online debugging and downloading of WCH RISC-V MCU, and also for online debugging and downloading of ARM MCU with SWD/JTAG interface. Connect USB to the USB port on the onboard WCH_LinkE of CH32V307V_EVT-R1. Configure WCH_LinkE: In MounRiver Studio, > Flash > Configuration. You can switch WCH_LinkE...

With openwch/arduino_core_ch32 , now we can develop  CH32 RISC-V MCU in Arduino IDE 2.0+/Windows 11. This video show steps to install arduino_core_ch32 in Arduino IDE 2 (fail to install version 1.0.4, then success in version 1.0.3). Then program  Muse Lab nanoCH32V003 (32-bit RISC-V development board) , and upload using  Muse Lab WCH-LinkE (WCH-Link Emulation Debugger Module) . Install arduino_core_ch32 in Arduino IDE 2 Add the following link in the "Additional Boards Managers URLs" field: https://github.com/openwch/board_manager_files/raw/main/package_ch32v_index.json Then search and install CH32 MCU EVT Boards by WCH. Currently, 1.0.4 is the most updated version, but fail: Downloading packages WCH:riscv-none-embed-gcc@8.2.0 WCH:openocd@1.0.0 WCH:beforeinstall@1.0.0 WCH:ch32v@1.0.4 Installing WCH:riscv-none-embed-gcc@8.2.0 Configuring tool.

It's a UART example run on Muse Lab nanoCH32V003 . Actually, it is the default Hello World generated by MounStudio Studio. It demonstrates that USART1 receives the data sent by CH341 and inverts it and sends it (baud rate 115200). This video also show the  Muse Lab WCH-LinkE act as USB to TTL serial adapter to communicate with CH32V003 via UART using RuTTY .

(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 everythin...
