1.The open-drain output is the same as the open collector output, which is the internal no load resistor.An open-drain output high must have a pull-up resistor externally between the output and the positive supply (VCC). Otherwise only high impedance states can be output.2.A is the normal output (there is a pull-up resistor): The field effect tube on the output low potential , the output high potential when the cutoff.B is open-drain output, external pull-up resistor: field-effect tube on-off ou

Csdn is getting better and better. I hope to add a pin in the blog of devteam. After logging in these days, I suddenly saw it. However, there is a feature that you do not want to add, and the feature is also added. Some themes seem to have added a feature for recent visitors a few days ago, which I think is very bad. I learned this from Sina? I don't think it is necessary.ProgramPersonnel, blog platforms that focus on technology, too much content wil

First, the database location analysis database Oracle 10g r 2 01 Secondly, two processes are developed for the moment called attribute process and transaction process. Obtain related data from the same big table and insert different tables. We should say that the two processes do not lock related objects! Second, both processes run well. Later, we used toad to run the process log table. Alter table ba. t_base_sp_runlog cache;Alter table ba. t_base_sp_runlog storage (buffer_pool keep )

Ruling pin-breakpoint The rod of the ruling, codenamed "ruling", is a very powerful weapon in fantasy, has the power to judge the ruling, and has the responsibility to monitor the sentient beings. I think there is something in common with the breakpoint, because the breakpoint can do what I want youProgramWhere to stop, you have to stop. I want to see what parameters of the program depends on what parameters of the program. Of course, the break

And of course there are other ways to replace them, such as:Some Linux versions have Dos2unix programs that can be used to remove ^m.Error reason : When writing a script, the script was edited using UltraEdit, and th

1, we search in the Win10 interface "Services", and then double-click the search to "service" open access, the effect is as follows 2, and then in the Service list interface We then find the IPSec Policy Agent, double hit open its properties. 3. Set the service startup type to "Automatic" and click "OK" to save the settings. 4, and finally manually open the service can be Well, the above is small series for you to introduce the PIN
