12CAD datasheet & applicatoin notes – Datasheet Archive

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 12c2052af, from scratch.

If you’re fluent in Mandarin Chinese, there is considerably more support and code sharing since the product is sponsored by the Chinese government.

Is it possible to datashedt arduino to program this chip? 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.

Upon wake up, the processor waits for a certain time for a serial character to appear on a predefined com port. If it does, the bootloader process is invoked, otherwise it jumps to the user program. There are tons of STC “development boards” on Aliexpress.

If you don’t know thestart here: Outside of the domestic Chinese market there is zero, zip, nada support. They have had two websites in the past, sometimes it 12c2025ad be a challenge to find what you’re looking for.

I guarantee you the journey will be long. Rather than issuing a reset to enter the bootloader code, you toggle VCC.

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


Find one with the same series part you have 12C and start there. Realistically, you need at least one more original “flasher” board for testing and experimentation.

If you’re someone who gives up easily, don’t start. You’ll need a logic analyzer to figure out what display driver you have.

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: Downloading a program is similar to the Arduino process with several exceptions. Another starting resource is Github. Hi got a flasher, I removed the case to see what’s inside.

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