BackgroundI have purchased and built 2 LED Matrix cubes from AliExpress. They are this type:
https://www.aliexpress.com/item/32853366041.html?spm=a2g0s.9042311.0.0.27424c4dvT9DIdAfter weeks of trying they said they could not supply any software or instructions on the unit. I got them built okay but I was interested in the WiFi, the mobile App, the Sound to Light and the remote control.
After days of searching I found what seems to be the correct zip package. I will give a link here as there are MANY people complaining that they can not find any software or support for these cubes.
https://drive.google.com/open?id=168var_nNprlkf-gPrFDGTQoDvgAKZGJNAdditionally I will add some details in this post as a log for others in the same situation.
All I really want to do is just upload some more LED sequences.FeaturesWiFi & mobile App: The ESP01 WiFi Module is seen and I can connect to it using the Android phone app in the ZIP file. This all seems to work okay.
Sound Activated: The inner most 3.5mm jack is the sound input and the cube reacts to sound when set in that mode on the phone APP or with the mode button on the front on the cube. The cube displays Note symbols when in that mode.
Remote control: There are no instructions for the small remote control but you can change the led display speed. Apart from that I am lost!
SpecsMCU: Labelled as IAP12C5A62S2 (Maybe a STC clone of a 12C5A6062)
Support chips: 8 x 74HC595D shift registers (used as Serial to Parallel converters), 4 x 4953 Dual channel P type Enhanced MOSFET (used as power drivers for each layer I believe)
The front buttonWhen the cube starts up it seems to just display sheets of LEDs so I image that is just a test mode. The front button seems to change its modes but I have no idea what they are apart from one which displays a music symbol. That mode the cube responds to sound on the 2nd 3.5mm audio socket.
This is one of the most important missing bits of information about what the other modes do. The one that seems to show the most patterns initially looks like it displays a 2f but this could well be a Chinese letter/character.
Questions/IssuesCan not get a sucessful response from the cube via a serial connectionUsing the proveded PC software
3D8S_alpha.exe ...
... and other similar software, I can not get the cube to respond. The cube is running the stock firmware and I am using the stock software so it should respond okay. I am using the supplied TTL to USB converter (Prolific & installed driver) and I have also used one of my standard converters (CH340 & driver) that I use on everything.
I found a text document in the ZIP file that said about powering the cube from the power cable not the comms adapter which I was doing anyway.
CHINGLISH...
Because the current of light cube will affect the downloader,
so 5V line does not need to connect, supply power directly with the power line,
when downloading the SCM needs cold start,
means that the SCM needs to power off and then re-power on before downloading) the power switch as a cold start,
after downloader finish connection, you need to disconnect the switch and then re-power to download,
the host computer's connection method is the same, use the power cord directly powered.All I really want to do is just upload some more LED sequences by updating the firmware via serial.
I have seen on Github some firmware that will let you control your cube 'Live' on your PC. I am unsure if this will even work on my model of cube and it is not really what I am after. I just want to add/change/make new patterns. If I have to wipe the existing firmware and loose the currently working Android App feature via a ESP01 WiFi module I may still do that. All I want is a cube full of patterns that runs itself.
There is very little online for this cube so any help is very welcome!
