Pinball FX3 Williams™ TALES OF THE ARABIAN NIGHTS
1 have 12 of these and have absolutely no idea what I can do with them. Purchased by mistake. Can I install wled on them?
first 2.8”, then the cheaper 2.4” now 1.9” ? Is at least the resolution the same?
Program name
How many open gpio pins does it have?
Name from the Programm?
Where to buy it?
Where to buy it?
This can be really usefull thanks !
Looks great !! I want to get going with a simple Z80 project soon . Do you have a project description for this project ?
How to change frequency using clock circuit
This looks amazing! Try running basic on it, make a special code to make a driver which will allow RCA connectors, then you got a computer! Thats what im making, originally planned to use the famous, one and only 6502 CPU. Sadly, when i got it i got scammed. It was not the 6502, it was some chinese CPU which worked like a ATMEL arduino chip. But i did get a hold of the Z80 thank Goodness, which I really like
I have a problem here i ordered some 8 pin microcontrollers with sop 23 package but forget the coustom pcb for them ... How can i use them with these normal board if no... Is there any other way without using coustom pcb or any other way ... please help me ...men 🥲
This wont work. The P mosfet wont close fully so the current will get through even if its closed. You will be able to use this circuit once.
I saw some recent reviews of people describing such issues. I'm working with a TTGO t-display now but thinking of getting one of these CYD's. Thanks for the fix tip. 👍🏽
I would greatly appreciate if you could provide some explanation.
Brother, your comment also used to get deleted automatically, that problem has been fixed please tell.
I have not tested to build this, but when you press the OFF button and don't release it, the led doesn't turn off until you release the button. So this kind of circuit may not work in all situations.
So, what’s an example of a sophisticated, ‘high dollar’ wave form generator?
Almost everything else will be more high-dollar. 😁 A higher-end waveform circuit could be created using specialized ICs (such as XR2206 or ICL8038) or MCUs with built-in controllable DACs. If these options aren't adequate, external DACs could be considered, possibly integrating an FPGA or higher-end MPUs for extensive control. Such a system would be capable of generating various waveforms and protocols at high speed, with a wide amplitude range, and would include features for modulation (ADC channels, GPIOs, and other inputs), measurements, etc. There are also options like op-amp waveform circuits. In general, these circuits can generate higher frequency waves than 555 circuits but suffer from similar problems as 555 circuits with none or poor adjustability and features. This is an example of another waveform generator with resistors and an Attiny: ruclips.net/user/shorts27xqN26_U9w And an example with MCU(Atxmega) and built-in DAC with DMA, which can generate nice waves without distortion up to 150kHz: ruclips.net/user/shortsfySTUIPW4vw
Thanks
Top gedaan! Ben zelf ook begonnen aan iets gelijkaardigs. Zou idd top zijn als we je code ergens konden bekijken (qua logica) etc!
I want to put this on my tone control bass for my subwoofer, would his work perfectly or would need to put additional components?
No UART project in your GitHub profile kindly share link
mine look like spec not correct this my board have flash only 8MB and don't have PSRAM and i order from china
There are a bunch of variation of the kind of board, some with more flash and less features, some with more!
What do you mean here ? Do you mean is it a software problem ?
beautiful illustration
Your technological distinctiveness is worthy of being added to the Collective's perfection. It will be assimilated 😮😢😂😅😊
Coincidence! I am also soldering a ch32v003!
Nice! I've got some CH32V003 chips myself. Currently, I'm working on a 6502 emulator written in RV32E assembly for these chips. However, the one I'm soldering in the video is a CH32V203, which is the big brother of the CH32V003. It features the V4B core instead of the V4A core, runs at 144MHz instead of 48MHz, and includes a USB 2.0 controller, etc.
This is so cool

Sorry for all the shaking, it's because I'm sitting behind the camera, with stretched-out arms and unable to rest on the table. After a couple of minutes, my arms start to shake.
I forgot to include two 100nF caps and a pull-up resistor in the part list. The pull-up resistor is optional. I've connected the RST pin to VCC via a pull-up resistor so that I can easily add a wire without desoldering anything.
Lo malo que nadie me explica el switch mode de cómo funciona el punto y la barra no hay un diagrama para eso
The dot and bar pin is a mode settings pin that changes the behavior of the outputs. When pulled high, it's in bar mode, and when pulled low, it's in dot mode. "A single pin changes the display from a moving dot to a bar graph." The datasheet shows the mode pin directly connected to VCC or GND.
What's the name of the song 😢😢😢
Vampire by Emmit Fenn. You can download it from the RUclips Music library. I'm a bit curious, why does that make you so sad? 😋
Heb je dit systeem ergens op github staan oid?
Sorry, I don't have a project page. It's an old project from 2014. However, I do have a video demonstrating the PH circuit used for this computer: ruclips.net/user/shortshEUJX90VsKk
Does this project on github?
Not jet, but if you want the code I can upload it?
@@PeetHobby It''ll be cool, if it's not hard for you!
Where is the power source for motor? My biggest confusion is how does the current flow with 2 power sources? 5v being the internal logic and other power source for motors.
There is only one power supply. If you see multiple positive traces in the schematic with the same name, such as +5V, it means they are all connected to the same +5V trace. Therefore, all the +5V connections in this motor example are linked to the same power supply.
@@PeetHobby the motor has to run off a separate power supply
Project link?
Which app ???
nice, i purchased a 10 uns, but how insert it in a protoboard??
You don't insert dev boards with double rows; you lay them next to a breadboard and use wires. Or, you can skip the breadboard altogether and connect peripherals directly to the development board.
what is the step angle of these motor
where you buy these
Chào bạn.Có thể cho mình hỏi 1 chút về con vi điều khiển này được không. Con vi điều khiển này có được cấu hình bằng CubeMx và lập trình bằng keilC đc ko. Nếu không thì nó có thể lập trình và debug bằng phần mềm nào. Nó hay bị lỗi của hàng fake giống như của mấy con Stm32 f103 rẻ tiền của Trung Quốc ko. Cảm ơn rất nhiều😊😊😊
Hey! The invitation to watch the latest crime documentary video is still valid. Perhaps this video will catch your interest.
i2c?
No, is SPI and the LCD controller is ili9341. Edit: Or did you mean as a solution? In that case, no, I2C is too slow for larger color screens with 16-bit data per pixel. Hardware I2C in MCUs often max out at 1-2MHz and has more overhead.
Which ide is this?
That is MounRiver Studio, the IDE provided by WCH themselves. Is based on Eclipse, with RISC-V GCC V8 and V12 compilers. Supports the CH32V and CH32F series, as well as chips like CH582M and so on.
@@PeetHobby i am currently using embeetle, if you have a chance, can you give it a try, i found it easier to handle.
I made a mistake, the main power supply is adjustable between 5-30v. And spilt power supply is adjustable between +-2.5v and +-15v.
😂this not computer !
Tell me, what's your take on what a computer is? 😁 I think you can see this as a minimalistic Z80 computer, it has a CPU, RAM, ROM, and terminal output and input. It can run Z80 programs written for any other Z80 computer, along as they fit in the ROM and RAM. It's essential a Z80 computer emulator with a real Z80 CPU, sort of a hybrid emulator(?). I've run the small text-based game from the C64 on an Arduino C64 emulator with a TFT as output. Haven't tried that with this Z80 yet, but I think that should be possible to run small text-based Spectrum games with it.
You’re right, there’s two computers in this video.
@@wcg66technically, there is one computer, and two processors. So kinda like modern PC, where one processor does computing and another one does graphics
Why the gain is only 1?
No particular reason; you can increase the gain if your project requires it.
Cool
needs to be explained..amen
What do you want to know?
