Let UV4 support STC microcontroller-EEWORLD

Collect

Keil itself does not come with data for the STC 8051 microcontroller, which makes it very frustrating to use. Fortunately, a young man in China has compiled a patch.

This patch contains three fixes:

Chinese character bug correction is a commonplace issue. It is strange that Keil has not corrected this in the past ten years, which shows its complete indifference to the Chinese market.
STC header file
STC Device Database

OK, this patch is enough for general applications, but it is still a little insufficient for people who pursue perfection, because this patch will overwrite the UV4.cdb device database that comes with UV4. After applying the patch, the latest UV4 database will be lost.

How to solve this problem? In fact, since UV2, the function of user-defined device database has been supported. We can modify it as follows:

Back up UV4.cdb
Installing the patch
Modify C:KeilTOOLS.INI and add the following under the [UV2] section:

CDB0=uv4custom.cdb("STC 8051")
Rename the patched UV4.cdb to custom.cdb
Restore the backed up UV4.cdb

This way, the next time we select a device database, UV4 will ask us which library we want to select from.

What is the role of RAM in a microcontroller?

A single-chip microcomputer is a small computer. Although a flea is small, it has all the organs and can even jump very high! Naturally, a data storage system is indispensable for a large computer, and a small single-chip microcomputer also has it, and it is often integrated with the CPU, making it more compact and fl

Introduction to AVR MCU 1: The structure of MCU embedded system

1. Structure of a single-chip embedded system A single-chip embedded system generally consists of two parts: hardware and software. The hardware part is divided into a single-chip control chip (i.e., a single-chip microcomputer) and peripheral circuits. The peripheral circuits are divided into basic system circuits

Why do we need chip select control and address selection for microcontrollers?

Answer: In the single-chip microcomputer application system, all peripheral chips are connected to the single-chip microcomputer through the bus. The single-chip microcomputer data bus transmits data with the peripheral chips in a time-sharing manner. In order to make this transmission reliable, chip selection control
