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...
[size=4]:pleased:I have always felt that difficult problems are accumulated from simple knowledge points. Similarly, if you want to carry out more advanced and complex designs, you must first lay a so...
