Hello CH32V307, flash & run GPIO_Toggle example on CH32V307V_EVT-R1, to blink LED and monitor USART.

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 between WCH-LinkRV and WCH-DAPLink mode.
- WCH-LinkRV (BLUE LED OFF) for RISC-V
- WCH-DAPLink (BLUE LED ON) for ARM
To work with CH32V307, have to set WCH-LinkRV mode (BLUE LED OFF).

Build and Download code:

In MounRiver, 
> Project > Build All
> Flash > Download

To monitor the output of GPIO.
Connect a wire between PA0 on J6 to LED0 on J3, you can notice that the onboard LED0 is blink.

To monitor the USART output by printf():
> Window > Show View
> Other...
> Terminal > Terminal

FNIRSI 2C23T 3-in-1 Dual Channel Oscilloscope/Multimeter/Signal Generator Steps to upgrade of FNIRSI 2C23T 3-in-1 : Remark@2024-03-23: Please check the comment by dmitriivanov5330 in the video. How to distinguish the hardware? please press menu , and if you can see the words in Setting: "Hardware version No.:XXXXX " then the device is made with latest hardware, it has the latest firmware, and now it doesn't need to upgrade.  If you can not see the words in Setting: "Hardware version No.:XXXXX ", then it is made with old hardware, and it can be upgraded with firmware 2.0.2, and if you confirm this, the firmware for the device with old hardware is attached.  By the way, the firmware 2.0.2 only fixes device with old hardware. The device with new hardware can not use this firmware to upgrade. - Download firmware from FNIRSI Official Web Site - Connect USB to PC - While 2C23T is OFF, press and hold MENU button, then press POWER button to power...
