than the USB camera, which is a more expensive reason for it.Then there is a question, why take a picture for 7 seconds?Increase the-v parameter to view debug information:raspistill -o image.jpg -rot 80 -vYou can see a line of information inside: Time Delay:5000 . Then look at the command document and find that the default-t parameter equals 5000, which will wait 5 seconds before taking the picture.Then increase the speed of the-t parameter set a little bit faster, it is true, but in the test f

' App_group_list ' = ' home,admin ', ' default_group ' and ' Home ',
Although the new independent group can completely replace the original normal grouping mode, but in order to take into account the original group project smooth upgrade, this new version adds a configuration parameter:
The App_group_mode is used to configure the grouping mode, which defaults to 0 for the original normal grouping mode, and if set to 1, the

The traditional procedure for running an ASP. NET Web site or WEBAPI is to install Libgdiplus, install Mono, and then install Jexus. In this process, although it is easy to install Jexus, it is relatively time-consuming and laborious to install mono.The situation is different now, in order to overcome the tedious installation of mono, simplifying the deployment of the ASP. NET WEB application on the Linux operating system, we have created a " standalone
