I'm driving a segment code LCD screen, but it's not very clear (it's only clear when you look at it diagonally, and it's blurry when you look at it from top to bottom). It's not clear when the scannin...
How do I define global variables in Verilog? Because several modules need to use the same variable, such as: reg[7:0] time_counts; how can I use the time_counts variable in both the av file and the bv...
[align=left]I drew a board. The input power is 3.3V. I used a 3.3 to 5V chip TLV61220. I found that the chip output is less than 3V after powering on. I started debugging. [/align][align=left]This is ...
Preface:
It has been a long time since my last post! I have been answering the same question for a long time, that is, how to successfully burn the program (because I have not been able to burn the pr...
Hi everyone, I have posted a question in the VB area, but maybe the friends here are more familiar with hardware, so I would like to ask you for help. In short, I have a small program that simulates t...

Pulse oximeters, non-invasive instruments used to monitor a patient's blood oxygen saturation, are benefiting from moving away from expensive discrete component solutions toward more integrated design...[Details]
Many medical applications require portable, self-powered devices that do not require external power and data cables. The most obvious example is a portable data logger that patients carry with them to...[Details]
The hardware circuit principle is shown in Figure 1. In the specific design, each part should consider the anti-interference problem to minimize the impact of interference on the performance of the...[Details]
In a Class D audio power amplifier, the preamplifier is a relatively important module. It is located at the front of the entire topology and completes the processing of the input signal source,...[Details]
Most
embedded
systems are powered from a 48V backplane. This voltage is typically stepped down to a lower intermediate bus voltage of 24V, 12V, or 5V to power the circuit board racks withi...[Details]
