Yesterday, the same program was debugged normally, but today, something strange happened. The debug did not respond. See the picture. I don't know what happened. Yesterday, I installed IAR software to...
CIRCUIT FUNCTION AND BENEFITSThis circuit utilizes the ADP2114 dual synchronous step-down dc-to-dc regulator to provide the individual supply rails required for the AD9268 dual-channel, 16-bit, 125 MS...
This is a document from a Freescale engineer, which compares the Freescale coldfire v1 core MCU with the hot ARM cortex m3 through experiments. It can be seen that coldfire v1, as the lowest-end archi...
I have an MFC program. The Release version needs to reference a C LIB library called Encryption InitInstance(). When it is initialized, only one function of this library is called (and this library on...

Wireless Sensor Network (WSN) monitors the target by deploying a large number of sensor nodes in the target area. WSN realizes the positioning and tracking of the target, determi...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
In order to prevent the lithium battery from being damaged by abnormal conditions such as overcharge, over discharge, and overcurrent, a lithium battery protection device is usually used to prevent...[Details]
Multimedia processors are often the most power-hungry devices in portable electronic devices. Common ways to reduce CPU power requirements are to reduce clock frequency or operating voltage, but th...[Details]
Designing low power circuits while achieving acceptable performance is a difficult task. Doing so in
the RF
bands increases the challenge dramatically. Today, nearly everything has wireless...[Details]
In recent years, the application of single-chip microcomputer systems in the field of industrial measurement and control has become more and more extensive. However, for industrial sites with harsh...[Details]
