I drew one before 24x16 dot matrix https://oshwhub.com/kurashizu/cheng-ben-5yuan-DotMatrix-24x16
, this time I drew a super mini version, and reduced the current limiting exclusion from 6 to 4, refreshing the mode Change from horizontal refresh to vertical refresh.
The layout is compact, and except for the lattice module, the rest are all chip designs and can be cooked in one go. Mass production is simply not that exciting!
The dot matrix is ​​66 pieces for 4 yuan and more than what I bought from Laowujia before. The test is all good, it’s so fragrant. The price of a certain treasure is basically around 1-2 yuan each.
 
The main control STC8G1K08A-8Pin squeezes out almost all hardware performance and works at 35MHz.
The current firmware can store 74 frames offline, which is approximately equivalent to 24fps video playback for 3 seconds.
When connected to the host computer, it can display banners, play black and white videos, and can also be used as a hardware occupancy monitor (displaying CPU, GPU, memory, network occupancy, etc.)
 
MCU firmware and Python SDK See the attachment. If you are interested, you can secondary develop some interesting functional
interface reference documents based on the ./lib/device.py driver library. See the ./lib/device.py comment.
The firmware code and the host computer code are all open source.
