STC8H8K64U Minimum Development Board

Overview

On the STC8H8K64U minimum development board for Mac, the programming

was tested by entering the command
: `shell
stc8prog -p /dev/cu.usbserial-14610 -e -f . / build/Debug /LearnSTC89C52RC.hex`
. When the screen displays " Witing for MCU, please cycle power: ", press the power button to start programming . (Images of the power button are included . )

Accessories - Sickle

These are ordinary handicrafts, accessories for another project. When I made them, I forgot to cut a window behind the flower and covered it with oil so it wasn't very translucent. I'm too lazy to change it, so you can modify it yourself if you want. As for the circuitry, you can figure it out yourself. The ceramic filaments are generally too short, and the packages in the library that are drawn according to the specified lengths are quite difficult to solder.

This sickle design is for personal reference; please cite the source if using it.
Gerber file is attached .

CH32V003F4U6 Nano Board

A Qinheng CH32V003 mini development board.

It was done rather hastily, referencing this project (https://oshwhub.com/maxgustav/ch32v003f4). I feel the pin header order could be optimized.

It uses the CH32V003F4U6, QFN-20 (3x3) package, and has full CH32V003 functionality. It has an onboard 24MHz passive crystal oscillator. Functionality has been verified.

The silkscreen printing on the prototype board in the image had a slight issue, but it has been corrected in the project files and should be OK now.

C64 PLA replacement

Used for repairing and replacing PLA chip 906114-01 in Commodore 64 computers.

The Commodore 64, released by Commodore in 1982, sold over 12 million units throughout its lifecycle, holding the Guinness World Record for "Best-Selling Single Desktop Computer Model." The PLA chip is responsible for memory address decoding. A malfunction manifests as a black screen upon startup. Because the PLA chip (906114-01) has been discontinued for many years, finding an original replacement is difficult. Therefore, a GAL chip can be used for simulation. This project is a re-drawn version of the PLA20V8 project. https://www.freepascal.org/~daniel/c64pla/

USB2514B-USB Hub Expansion Dock

USB2514B-AEZC-TR Dock

This high-speed 2.0 expansion dock uses

the MICROCHIP USB2514B-AEZC-TR high-speed and stable hub controller.
While the chip itself is relatively expensive, it's cheaper on Taobao, but refurbished units are common. I bought three, all refurbished, and one failed. It's worth a gamble; this design uses a refurbished unit.

The
circuit doesn't require programming; it's ready to use after soldering.
The speed of copying files via USB is shown in the image below. Playing internal videos from a Type-C SSD is also very stable and smooth.
Be aware of cold solder joints, as refurbished units are prone to this.
If the computer doesn't respond or displays a "USB device request failed" message, it's a soldering issue.
The CH340 port is recognized successfully, but a USB flash drive fails to display the "USB device request failed" message—this may be a chip problem .
This project uses a 0402 package.
