During the serial communication, I use PC to send data to MCU. On the transmission line, these data are transmitted at their corresponding levels. When the data is inside the MCU, someone told me that...
I bought the YL2440 development board from Youlong. The board has two SDRAMs connected to the BANK6 area with a capacity of 32x2MB. I want to connect two more SDRAMs to the bank7 area to expand the SD...
1 IntroductionWith the expansion of monitoring sites and the increase in the number of probes, the image display system at the monitoring end often needs to receive external data and display the relev...
[b][color=blue]This topic seems to be very old, because it seems to be a louse on the monk's head, everyone knows it. Domestic mobile phone companies lack technology, this may be the answer given by 9...
Designers use PSpice primarily to simulate analog circuits. However, it can also be used to simulate digital filters. The main components in a digital filter are delay elements, adders, and multipl...[Details]
TD-SCDMA (Time Division Synchronous Code Division Multiple Access) is one of the three major standards for the third generation of mobile communications. It is a communication standard with indepen...[Details]
As medical equipment develops towards intelligence, miniaturization, serialization, digitization, and multi-functions, the logic control devices in medical equipment have also evolved from medium- a...[Details]
Radio Frequency Identification (RFID) technology is a non-contact automatic identification technology that uses wireless radio frequency communication. Compared with the currently widely used barco...[Details]
