Any chance you can show how this works for the datalogger video from #24 ?

Hi, How to Generate 1ms tick uding sys timer or Timer using Interrupt. Is there any Arduino library is there for precise time interval generation ?

No Arduino library for Timer, External Interrupt

How to use ws2811 led pixel with ch32x

Looking For Periodic Timer (Interrupt base) Arduino Library for CH32V003. All peripheral Example for CH32V003 are needed for Arduino. Or how to Implement EVT Board Code in Arduino?

@rvmaking would it be possible to pair a two of CH9160? Like one CH9160 used as a USB dongle, and other one paired up with CH32V307? Could it be connected to USB port of MCU, to then create a wireless connection with PC?

Because PIOC is located on the SWD pins, shouldn't be a good idea to put a small delay before the pins initialization just to ensure not to brick the MCU??

Thank you very much for doing our request.

❤😊

Do you have a link to buy the 8k usbhid chip?

Can you flash the ch9160 to be gamepad?

Great video, sir. Do you have a code repo and a pcb schematic/layout available?

Hello. After flashing CH32F207VC6 through openocd from MounRiver Studio under Linux i try to do Query chip info in WCH-Link Utility under Windows, and result is failed. But before flashing through openocd, WCH-Link Utility works fine. What happened? Thanks.

Can you provide link for the sample project being used here?

Appreciate if you can post a video on how to setup PIOC module. Thank you.

Very useful tutorial...just got me a CH32V307 board, will be trying some code soon.

thank you for this video because its really rear to see this support channel to add a new video about its own microcontroller. i have uploaded much more videos even tough i have less knowledge about this controller.

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.

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?

flashing CH32V002 via arduino is not possible in Linux, USB not found error, WHC-LinkE appears as ttyACM0 flashing CH32V002 via arduino is only possible in w$, WCH-LinkE appears as COM(x)

Risc-V MCU is great.

good job.

Nice

Hello, is there any future plans on adding oled support or maybe Ethernet support like the winznet modules?

How to achieve 6mbps Max baudrate?

at 0:29: WCH-LinkE photo is wrong, it is WCH-Link (without "E") , it cannot program CH32V00..

Wonderful, thanks!

Just using bitbang and I call it end of day ! 3 bytes per pixel less code size simple to use.

Are all boards in the CH32V307 supported in the Arduino IDE? I only see a selection for CH32V307VCT6.

I haven't gone through all your videos yet, since I just subscribed. Did get the CH32V003F4P6-EVT working - because of your help. I'm wondering if it is possible to do PWM on some of these pins, like we do in the Arduino and other boards. I don't seem to see it called out as a function on the CH32 boards.

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?

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

Great opportunity to make Qi-capable device with lower BOM. Where can I buy some of this MCUs and possibly a dev board? Nothing is available from Ali shop and 3rd party sellers.

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?

Hi, can i use ch32x035 USB pd to make a pd charger that can supply 20v or can it only act as client side

Hello, can you help me with one problem? I want to make an automatic window blind with servo and photoresistor, but i couldn’t figure it out, thanks CH32V003J4M6 Using only chip, without board

I use minichlink for this. The "-u" option will "unbrick" a chip. It needs to control power and be connected to pd1. I have never had it not work and I have tried to. I disabled PD7/nRST and PD1/SWDIO set them to GPIO immediately on startup. It still reaet it.

Im glad i found this channel. It helped alot in terms of understanding design. Thanks for your demo.

Nice work, nice project, thanks!

Fun project!

please guide for check spi communication in ch32v003???

hey, how do you make a analogRead? with analogRead(PA2) or other Analogpins i got nothing in return? digitalread is working? any ideas? thx

*Abstract* This transcript details the design and implementation of a compact PDF-generating data logger that measures temperature and humidity. The device is built around the CH592 microcontroller, featuring embedded USB 2.0 for seamless data transfer to a PC. It offers up to 90 days of battery-powered data logging. Upon connection to a computer, the device autonomously generates a PDF report containing tabular and graphical representations of the collected data. This unique approach requires no external drivers or software. The transcript covers hardware specifications, program flowchart, and the PDF generation process. disclaimer: i used gemini advanced 1.0 to create an abstract based on the transcript.

*Abstract* This transcript addresses a common issue experienced by users of certain microcontroller units (MCUs) - the misconception that the device is broken when, instead, the PD1 pin is occupied. The video details how to correctly resolve this situation by completely resetting the MCU. This is achieved using the WCH link utility tool to clear all code from the MCU, thus freeing the PD1 pin and restoring full functionality. I used Gemini Advanced 1.0 to create this abstract of the transcript.

*Abstract* This presentation explores the creation of an Electronic Speed Controller (ESC) suitable for controlling brushless motors, such as those commonly found in drones. The design utilizes the CH32 V203 microcontroller and the AM32 firmware. We'll cover the basic principles of ESCs, along with the process of preparing the ESC, including flashing the bootloader and firmware. The speaker demonstrates changing the operational modes (PWM, DSHOT 300, and DSHOT 600) with a servo testing tool to provide input signals, showcasing the differences in frequencies and their impact on motor control responsiveness and power consumption. This project, utilizing WCH chips, illustrates the potential to create custom ESC controllers capable of supporting various configurations and protocols. I used Gemini Advanced 1.0.

In the case of CH340C, why can´t we just hook RTS and DTR pins to BOOT0 and nRST pins of a STM32 micro, and set them high or low as needed to enter and exit bootloader mode? Why there is the neeed to use a NPN and a PNP transistor?

Patrick, hello! Great job! Can you share the source code of the project?

ordered mine, great device. Thanks for video

Is there way to do this via openocd?
