I’ve worked extensively with the STC chips and while they are decent, reliable and cheap, there is zero library support compared to Arduino.

If you’re someone who gives up easily, don’t start. Here’s an “english” datasheet for a similar chip: You’ll need dataeheet logic analyzer to figure out what display driver you have.
Downloading a program is similar to the Arduino 12c2052d with several exceptions. Rather than issuing a reset to enter the bootloader code, you toggle VCC. This requirement is well documented in the datasheets as previously mentioned.
They have had two websites in the past, sometimes it can be a challenge to find what you’re looking for. Find one with the same series part you have 12c2052ae and start there.
Another starting resource is Github. The other difference is that isolation diodes are required in the rx and tx lines of the serial adapter to prevent parasitic powering of the processor which would prevent the power cycle required to enter the 112c2052ad. Hi got a flasher, I removed the case to see what’s inside.
You can compile C based programs for the device with SDCC public domain and download with a serial device, these days that eatasheet a USB to serial converter plus a switch and some diodes which is well documented in the STC literature. I have found adapter boards with cable jacks to be easier to deal with so I can use standard cables rather than the extension cable that would be required 12c20552ad the plug on the front of the cp board. Is it possible to use arduino to program this chip?

If you’re fluent in Mandarin Chinese, there is considerably more support and code sharing since the product is sponsored by the Chinese government. Outside of the domestic Chinese market there is zero, zip, nada support.
If it does, the bootloader process is invoked, otherwise it jumps to the user program. There are tons of STC “development boards” on Aliexpress. STC provides demo code for using the timers, serial, PWM and ADC subsections, it’s up to you to make what you need which means you will be writing almost everything you need, from scratch. Upon wake up, the processor waits for a certain time for a serial character to appear on a predefined com port.
I guarantee you the journey will be long. If you don’t know thestart here: Realistically, you need at least 12f2052ad more original “flasher” board for testing and experimentation.
