I have used PADS to package the device and would like to print it out for comparison.I only know how to use CAM to print layer by layer. How can I print the pads and silk screen together to form a com...
I am currently adjusting the SD card (2.0 protocol) driver. Its read and write speed is very slow, writing about 200KB/s, and reading is about 2-3 times faster than writing. The communication mode I a...
[size=4]The designed board has reached the SRIO debugging stage. On the board, one V6 and two 6678s are interconnected through 4XSRIO, without a switch in between, and finally the communication betwee...
1 AMBA AHB byte strobe problem
For example, my memory is 32 bits wide. ARM is a byte-aligned operation, and the byte is selected by the lower two bits of the address. That is to say, after receiving t...
Magnetic resonance imaging (MRI) systems can take high-resolution cross-sectional perspective images of the human body, providing very useful information for medical diagnosis. The radio frequency pro...[Details]
The role of digital-to-analog converters
Real-world analog signals, such as temperature, pressure, sound, or images, are constantly being converted into digital form that is easier to store, p...[Details]
Magnetic resonance imaging (MRI) systems for medical and scientific applications require a high-performance, high-power inductor capable of establishing a uniform, strong magnetic field. Transverse el...[Details]
A biped robot joint constructed by pneumatic artificial muscles is introduced. The joint uses the flexible characteristics of pneumatic artificial muscles to effectively control the impact of the la...[Details]
Conventional ECG recorders are one of the main means for doctors to diagnose heart diseases, but they can only record short heartbeats. In many cases, it is difficult to record ECG changes during a...[Details]
This issue will briefly introduce the test related to spectrum - occupied bandwidth.
Definition: Occupied bandwidth refers to the bandwidth corresponding to 99% of the total transmitted power, cent...[Details]
Many MEMS devices, such as accelerometers and mechanical resonance devices, require a vacuum environment to realize their designed functions. However, verifying whether the package cavity has reach...[Details]
In the future, a complete automobile safety system must fully combine gyroscopes, accelerometers, steering wheel and brake pedal position detectors, and tire speed detection systems to accurately ...[Details]
