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...
As the title says, the project needs to set a timeout and use clock() + time to set the timeout time, and then compare whether the current clock() is greater than the set time to determine the timeout...
A differential input amplifier, no matter it is bilateral input or unilateral input, I have seen many circuit diagrams that add a 5V pull-up resistor to the output pin (I don't know if this statement ...
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]
In order to prevent traffic accidents, when the intelligent detection device of the car detects danger ahead, it must send a warning message to the driver. The voice alarm clearly reminds the drive...[Details]
