I recently ported the TCPIP protocol to LPC2292. During the test, I found that the program ran away. After looking for the cause, I found that when assigning the first data to a structure pointer poin...
[size=4]When it comes to lithium-ion batteries, we should think of several parts: [/size][size=4]battery cells, fuel gauge, battery protection board, and battery charging circuit. [/size] [size=4] [/s...
As shown in the figure:What is the function of the components in the red box in the above figure? What is the benefit of this connection? The two ends of the LED are connected to a 5V power supply...
I want to collect several DC voltage signals to the computer, and then output them to the peripheral to display some numbers after calculation. I don't know what hardware circuit is needed? Because I ...
First of all, the LPC1114 board is not easy to separate. My only tool is a pencil sharpener, so I just cut the PCB line. Last night, I separated the power supply of the peripheral circuit and the chip...
I haven't posted in the analog section for a long time, which also means that I haven't touched circuits for a long time. Except recently, because I was tossing this ultrasonic ranging circuit. So I d...
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]
