Based on years of designing industrial control products, I think that industrial products should be reliable and safe first. Secondly, they should pursue accuracy, beautiful interface, and easy operat...
The manual says that before starting ADC calibration, the ADC must be powered off for more than two ADC clocks, i.e. ADON = 0.But why does the routine first enable the ADC (ADC_Cmd(ADC1, ENABLE)) and ...
I recently planned to work on wireless ad hoc network communication. I saw the contiki operating system and it seemed like a good fit. But I have a few questions: Does contiki have any hardware requir...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
