You’ll need a logic analyzer to figure out what display driver you have.
Hi got dstasheet flasher, I removed the case to see what’s inside. I’ve worked extensively with the STC chips and while they are decent, reliable and cheap, there is zero library support compared to Arduino.

They have had two websites in the past, sometimes it can be a challenge to find what you’re looking for. Outside of the domestic Chinese market there is zero, zip, nada support. Rather than issuing a reset to enter the bootloader code, you toggle VCC. If it does, the bootloader process is invoked, otherwise it jumps to the user program.

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. This requirement is well documented in datasheeet datasheets as previously mentioned. 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 for the plug on the front of the cp board.
Here’s an “english” datasheet for a similar chip: If you don’t know thestart here: Find one with the same series part you have 12C and start there.
The other difference is that isolation diodes are required in the rx and tx lines of the serial adapter 112c2052ad prevent parasitic powering of the processor which would prevent the power cycle required to enter the bootloader. If you’re fluent in Mandarin Chinese, dataasheet is considerably more support and code sharing since the product is sponsored by the Chinese government. I guarantee you the journey will be long.
Downloading a program is similar to the Arduino process with several exceptions. You can compile C based programs for 122052ad device with SDCC public domain and download with a serial device, these days that means a USB to serial converter plus a switch and some diodes which is well documented in the STC literature. Upon wake up, the processor waits for a certain time for a serial character to appear on a predefined com port. Realistically, you need at least one more original “flasher” board for testing and experimentation.
There are tons of STC “development boards” on Aliexpress.
Is it possible to use arduino to program this chip? Another starting resource is Github. If you’re someone who gives up easily, don’t start.
