Hello everyone, I work in the inverter industry, my main job is DSP development, and I have been in the industry for less than a year.
I have recently encountered some problems at work and there is no...
More than two decades ago, engineers working on RF circuits envisioned an “ideal switch.” These switches would have ultra-low resistance when “on” and ultra-high resistance when “off.” They would also...
CC2541 has four oscillators, namely:32MHz external crystal
16MHz internal RC oscillator
32kHz external crystal
32kHz internal RC oscillatorFrom this we can see that CC2541 has its own oscillator, that...
The last time I used these two USB shields was probably ten years ago. I don’t need them anymore, so I took them apart and took a look.Use a flat-blade screwdriver to pry open a crack along the gap, t...

There is no column for viewing GPIO registers in the VIEW menu in CCS5.5, but considering that the status of the 32 ports of GPIOx are all in GPxDAT, the value of GPxDAT can be viewed in the memory vi...
With the disappearance of the demographic dividend and the continuous increase in labor costs, traditional manufacturing has gradually shifted from labor-intensive to technology-intensive. More and m...[Details]
In order to monitor the environment around underwater robots, a design scheme for an underwater robot environment monitoring system based on PC104 and C8051F120 was proposed, and the system's softwar...[Details]
Unlike incandescent lamps, which radiate heat, the heat generated by LEDs must be dissipated away from these semiconductor devices by conduction. Without proper thermal management, LED light output...[Details]
1 Introduction
In the process of designing and debugging automatic control systems, sine waves, triangle waves and square waves of different frequencies are often used as signal sources, which are v...[Details]
