My understanding of the sentence with blue background in the picture is that in order to further reduce the influence of parasitic capacitance of negative input pin, a space should be left for ground ...
I have been engaged in PLC programming for a year, and I feel that I have to design a separate program for each device I encounter. Do you have a universal program template that can be applied?...
[i=s]This post was last edited by paulhyde on 2014-9-15 03:10[/i] It is said that orthogonal signals are needed this year. How can this be achieved using AD9851? Please give me some advice!...
How big is the imagination space for pressure sensing?
Will said that MEMS pressure sensors are a new interactive method compared to traditional touch. Intuitively speaking, "touch" is an action, and ...
I'm doing AD conversion recently. The specific situation is as follows: I use the voltage of the potentiometer as a given value, and through AD conversion, the conversion result is used as the basis f...
Basically, all the systicks that can be searched are used for delay, because the design requirements are more practical for system time judgment. If I have an LED that needs to flash every 10 seconds,...
