EEVblog 1524 - The 10 CENT RISC V Processor! CH32V003

Now imagine the potential of those super little beasts in 10 years or so!

Bit banging over USB-C

That’s funny

eclipse can be configured to auto save before build

I downloaded the EVT zip file for this chip but I cant seem to find examples for doing floating point or scientific calculations. Unlike Microchip PIC ("the boss"), the compiler guide is readily available and properly documented.

You have to close other projects to make flash and debug work properly

I've downloaded the MounRiver Studio Community package twice and both times there were no examples at all. Searched everywhere. Anyone know how Dave got them and how I can find them? Cheers

Just found this video. I enjoy these diamond in the rough finds even though I haven't done more than intro blinky programs with arduinos. Does this channel or anyone else give a good breakdown on what is the point you would consider one of these less well known MCUs like this or the one by Paduak over the ones with the bigger community like PICs and Arduinos?

Be nice for a programmable keyboard or several other types of peripherals

We are testing this to add an automatic closing function to the bathroom ventilation fan. About 40% cheaper than comparable MCUs. Compared to the STM8, it's almost free.😁😁😁 My only concern is that if they don't last long and discontinue the product, the STM8 won't be a cost-effective alternative.

Nice video, thank you for sharing it :)

Does someone know which oscilloscope is used to study the behavior of the board ? Thanks :)

The more vital thing is how available development tools.

Wish I had one of these in High School in 1982. Amazing!

The "WCH CH32V003 48MHz RISC V processor demo board" is 19990 cents + 15000 cents shipping, not 10 cents. Very intentional misinformation to make people watch the advertisement.

I'd love to see some kind of project with the cheap RISC-V chip

Looking forward to using this chip!

I dislike hardware manufacturers optimizing for time to hello world by bundling a huge ide instead of just making sure upstream compilers work out of the box

This chip is 20 cents now . Any 6 , 8 pin micro running at 32khz under 8 cents similar to Padauk , Padauk programmer is difficult.

saving is necessary in order for make (or any other dependency tool) to pick up on the fact something is changed and need re-compilation.

I clicked on that datasheet link and it gives me a summary datasheet.. a tiny fraction of the full datasheet.

It's crazy how far things have come in the last 10-15 years. The last time I programmed a micro in anger was an AT90S2313 with all of 2K flash and a whopping 128 bytes of SRAM, you practically had to use assembler in order to cram all you needed into that space, it's nice to have the luxury of a high level language for a chip at an affordable price. I can imagine there are some old grackles on here that will be rolling their eyes and going "Baaah! back in my day we had to write everything in ones and zeroes, and before that we didn't even have zeros and had to use the letter 'O'" (to paraphrase a Dilbert cartoon)

Many interesting products made in China included this MCU.
May be Risc-V replace the ARM in Apple products. Intel x86 is history.

2023. They’re now selling this on a tiny development board for $1.50, or a bigger board with USB for $6.00!!

I think in five years or so China will be making TSMC quality chips. Seems the world is wanting that.

This needs to be the future: how small, simple, and lightweight can we make our tech?

I like how this fool acts like he knows what he is doing....

Dave,
I can't stand your voice or your attitude.

Will it eventually be possible to program from the Arduino IDE?

I ordered the evaluation kit and finally received it. Only issue I had was to get the MounRiver IDE to generate a hex file. I dug into the Settings an found the setting under "GNU RISC-V Cross Create Flash Image/General. I selected Intel HEX in the drop down and all is well.
Thanks for the Video I was looking for a device that did not require the investment of the Keil development software. Thanks to you and WCH!

u write 10cents but the link only show a dev board for 20 us dollars . wheres the lnk to buy only the chips for the 10c ?

Damn, that is cheap

Hey I have some problem with console - COM does not appears when I click on console toggle button. Do I have to setup something? I can open COM with different application, so it works fine.

It's funny how so much of it is either ripped off or based on STM32. Chip naming scheme, memory map diagrams in the datasheet, function names and mich much more :)

Hmm. I went to Tindie to look for one of these - they had them - but at $9.90 USD each. How is it the CTO (Patrick Wang) says the price is under ten cents, but nobody can find them anywhere? But I put my order in, and s/b getting the demo board (not the chip alone), because I expect (hope) to be able to find something eventually closer to the 10 cent price for my projects. And I love the Eclipse IDE! I used it once before to teach myself Java; fantastic IDE! I have missed Assembly language too.

ey. whicsch is better. mcu or mpu. idk

Actual price right now on Ali is about $30 incl postage for the kit you have

WHC official store on Ali has these in at £6 summat plus postage for 50. I just got 200 of them to go with the dev kit. I'm hoping to use them to drive leds

Ming has been feeling out the sending out of his "certain sequence of events" balloons....

Somebody is very confident in the abilities of his virus scanner. I'd have set up 5 nested VMs before I touched that software with a 10 foot pole. Even if it's just because the whole aesthetic looks like one of those sites, where you have to find out which one the real download button is.

I have the development kit but entire document is in Chinese

Can you help in its development support

Imagine, 10 cents for a powerful micro-controller. I wonder how many MITS Altair 8800s it would take to match it. Amazing

yes but the balloon!

Interesting idea, Dave. It's nice to see that microcontrollers are coming at a good price.

16kB flash is enough for many projects, the 48Mhz is great! 8Mhz is already Ok most of the time.

10 cents is a steal deal, nice find Dave.

cool 😎 😎

I started doing embedded through Platformio, and then when a project required a bunch of the stm32 build tools, their eclipse based IDE was so miserable, that to this day I don’t like it. It had good tools, I just dislike the unnecessary complexities of the eclipse interface.

Perhaps I'm missing something. I did a search on LCSC and came up with a single hit for something called "CH32V003F4P6-EVT+WCH-LinkE" which is not $0.10 but in fact US$ 6.39, and there are 0 in stock.

I think however that a cheap price is not really the point, but rather access to reasonably priced and well supported risc-v microcontrollers. For the past week and a half, I've been playing around with an ESP32-C3 board, with the intent of being able to write risc-V assembler and do hardware debugging. I've been able to set up the environment on Eclipse and do just this. Turns out that the C3 chip V3+ (most of them) also has a hardware JTAG debugger built into the chip which is really simple to use. The board I'm using was from the "Estardyn Official Store" on AliExprss, costs CAD$ 3.12, and there are 358 available at this moment. Contrary to the 10 cent microcontroller, there is quite a bit of documentation available in English. Even if you're a moron and none of this makes sense, it's also supported on the Arduino IDE, so you can just plug it in and blink LEDs.

Just my opinion? ... (I don't mean to get political), but I imagine that recent hostilities by the usa towards China in the tech sector, is forcing the Chinese to come up with alternatives ... and risc-v must be high on their list, so I'd expect a huge growth in risc-v moving forward.

Thanks. Watched this a week ago. Did some research, bought some dev boards and have a few hundred chips on the the way. Have been using PIC since the mid 1990s and a few Atmel chips after Microchip took over, using MPLABX on Linux since it came out. MIcrochip once told me there wouldn't be Linux dev support because nobody wanted it. Always been troubled by availability and in recent times price. Price is not the most important thing. As long as chip availability from China remains good we may at last be able to leave Microchip behind. Over the past year have been using a few esp8266 and esp32, mostly modules but recently bought a few chips. Have a few products at the moment in transition from PIC to esp32.
