I guarantee you the journey will be long. STC provides demo code for using the timers, serial, PWM and ADC subsections, it’s up to dagasheet to make what you need which means you will be writing almost everything you need, from scratch.

Is it possible to use arduino to program this chip?

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. You’ll need a logic analyzer to figure out what display driver you have.


Hi got a 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 datazheet Arduino. If you don’t know thestart here: 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.

This requirement is well documented dataheet the datasheets as previously mentioned.

The other difference is that vatasheet 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. There are tons of STC “development boards” on Aliexpress.

Realistically, you need at least one more original “flasher” board for testing and experimentation.

If it does, the bootloader process is invoked, otherwise it 12c2502ad to the user program. If you’re someone who gives up easily, don’t start.

Here’s an “english” datasheet for a similar chip: Find one with the same series part you have 12C and start there. Another starting resource is Github.

Outside of the domestic Chinese market there is zero, zip, nada support. If you’re fluent in Mandarin Chinese, there is considerably more support and code sharing since the product is sponsored by the Chinese government.


Rather than issuing a reset to enter the bootloader code, you toggle VCC. They have had two websites in the past, sometimes it can be a challenge dataeheet find what you’re looking for. Upon wake up, the processor waits for a certain time for a serial character to appear on a predefined com port. Downloading a program is similar to the Arduino process with several exceptions.
