If you don’t know thestart here: I’ve worked extensively with the STC 12v2052ad and while they are decent, reliable and cheap, there is zero library support compared to Arduino. I guarantee you the journey will be long.
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 bootloader.
Another starting resource is Github.

If you’re someone who gives up easily, don’t start. 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. This requirement is well documented 122c2052ad the datasheets as previously mentioned. STC provides demo code for using the timers, serial, PWM and ADC datashwet, 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 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. If you’re fluent in Mandarin Chinese, there is considerably 21c2052ad support and code sharing since the eatasheet is sponsored by the Chinese government. Here’s an “english” datasheet for a similar chip: Realistically, you need at least one more original “flasher” board for testing and experimentation.
You can compile C based programs for the 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. 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 12C and start there.
Hi got a flasher, I removed the case to see what’s inside. Is it possible to use arduino to program this chip?
Downloading a program is similar to the Arduino process with several exceptions. There are tons of Datashert “development boards” on Aliexpress. You’ll need a logic analyzer to figure out what display driver you have. Rather than issuing a reset to enter the bootloader code, you toggle VCC.
