The search function of Hotai compiler is easy to use.

There is not much online information about Hetai's microcontrollers, and there are not many source codes for reference. It is really a lot of effort to get started.

However, fortunately it is a domestic microcontroller and the datasheet is in Chinese, which seems a lot more convenient.

Holtek Semiconductor was founded in 2012 and is affiliated to Taiwan's HOLTEK SEMICONDUCTOR INC. Group. Holtek Semiconductor is headquartered in Songshan Lake, Dongguan, Guangdong, China. It is responsible for the research and development, production, sales and after-sales service of HOLTEK products in China.

Hetai's development software HT-IDE3000 is not very friendly to C language support and may still have many problems, so it is recommended to use assembly.

Of course, if you're like me and don't learn assembly very well, you'll have to use C language, and you'll run into a lot of pitfalls during the development process.
