Concept of protection zone From the perspective of EMC (electromagnetic compatibility), an area to be protected can be divided into several levels of protection zones from the outside to the inside....
CodeGuard security enables partitioning and privileged access to on-chip memory for Microchip's dsPIC DSCs and PIC24H microcontrollers at no additional cost Microchip Technology Inc., a global leader ...
In the experiment, I used the ams1117 3.3 voltage regulator, and found that the resistance between vcc and gnd was several hundred ohms, and it was bidirectionally conductive. What effect does this ha...
This time, we mainly make two kinds of Uboot files, one is the version that can be started from NandFlash, and the other is the version that can be started from the SD card. (Both versions are explain...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
A single-chip microcomputer is also called a single-chip microcontroller. It is not a chip that completes a certain logical function, but a computer system integrated into one chip. In general, a c...[Details]
System design is a complex process. It is not enough to just use ICs. There are many details to consider. This article uses a high-fidelity music playback system as an example to introduce how to s...[Details]
