I have a stupid curiosity. I just received a CH32V003F4P6-EVT. When I run the GPIO toggle, nothing happened. But if I hooked up an external LED to PC_3, it did blink as programmed. I noticed in your program, that the LEDs on the board blinked. How did that happen?
Never mind. I did some trace tracking on the board and realized that there are LED pins. I see you simply jumpered PC_3 to one of those pins. :) I thought they might be built-in LEDs, so I spent a lot of time looking through the documentation to see how to access them. I should have simply looked at the board more closely.
First of all, thank you for your effort. Any suggestions about a problem: PD6 (RX pin) of the CH32V003F4P6 does not receive data over UART communication. PD5 (TX pin) works fine, sending data is not an issue. Tested with WCH LinkE + WCH-LinkE-R0-1v3 board and with ESP32 C3 too, CH32 was able to send but unsuccessful in receiving data. edit: Arduino Ide 2.3.2
Thank you soo much for this tutorial. I was wondering could you do a demo of the low powered modes using the Arduino IDE. and Posibly waking it up with a button. I would be very interested in seeing the real power consumption tested.
Thanks for making this video. The dev board I have is the CH32Vx03C-R0-1v0 (with the CH32V203 chip) and I am not sure if this is essentially the same as the the CH32V203G8U board you discuss in this video.
I noticed that you removed the XTAL from the board. Where can I configure to use the external XTAL? As a suggestion it should be mention in your demonstration. Thanks
Here I noticed that this simple led blinking program using nearly 65% of program memory space and more than 10% of RAM.. what's the reason? Is it bcos of Arduino?

It would be good to support their higher capability chips also. UART, DAC, ADC, WDT, hardware interrupts...etc. Just like on the reset of the Arduino supported devices.
Great work! Especially your documentation on GitHub is excellent! I'm still waiting for my WCH Link E. What I'm wondering: is this a normal CMSIS-DAP probe or something custom?

Hi there, just got this working, the ADC is disabled by default, you just need to edit the .arduino15/packages/WCH/hardware/ch32v/1.0.4/variants/CH32V00x/CH32V003F4/variant_CH32V003F4.h file and remove the '//' from the line that says #define ADC_MODULE_ENABLED
I've started using the ch32v003fun environment instead. It's a bit more complex than Arduino (which was great for getting started), but binaries are way smaller - 560 bytes for a 'blink' example for me.
In my case, after uploading the sketch, I had to disconnect LINK-E then connect it again, otherwise the LED wouldn't blink. The same goes for testing serial output. It would be better to reset uC like AVR.
@@petermuller608 Thank you! I did learn quite by accident that if you select D5 in your Arduino sketch, you have to run a jumper between PC3 and the LED pins on the dev board. I guess it's clearly labeled, but confusing for me none the less. Other wise the tools and hw run great, a lot of value for 7$ dev board, and sophisticated programmer/debugger. Batteries included totally.
You say Arduino IDE but show what looks like VScode IDE. After adding the supplied URL to 'Additional Bd Manage URLs -- Then WCH to Board Manager brings up nothing. Poor poor poor ! I won't be using ANY of this.
Please where is the link to download this software? WCH Serial Port Debug? I can't find it. TKS

Why plain blink spent over 60% flash? using Wire.h spent over 86%. It's stranger.
Hi I would like to use CH32V003F4P6 board to connect with LCD 16x2 display to show text messages, can I use Arduino IDE to implement it?

The dev board of V203C8T6 is a little bit different from V203G8, but it's easy to remap the pin-map file in .cpp source file.

How to configure ch32v003 timer interrupt for led toggle
Hey,
Is there also the posibillity to use Visual Studio Code with the PlatformIO extension instead of Arduino IDE?
It would be good to support their higher capability chips also. UART, DAC, ADC, WDT, hardware interrupts...etc. Just like on the reset of the Arduino supported devices.

I'm still waiting for my WCH Link E. What I'm wondering: is this a normal CMSIS-DAP probe or something custom?
I think it's selectable DAP-Link for ARM, or Risc-V programmer in software.
For V003, it's the 1-wire debug protocol. For V203, it's the 2-wire debug protocol.

Hello. Congratulations on the channel. Can you tell me if it is possible to use an internal reference for the ADC on the CH32V008?
You mean you wanna use the internal 1.2V for the reference of ADC?
@@rvmakingyes, because my VDD voltage cannot be stable all the time, it varies from 3v to 5v.
Great work! 👏👍😀

does the toolchain work on linux as well?
why the CH32 board doesnt have an on board USB to UART converter?
The WCH-LinkE has the USB-UART converter inside :)
