0x1 目的 先前用80行实现了一个极为简陋的虚拟机, 它虽然也很好的对 VM 进行了抽象(指令集, 程序, 栈; 取指令、对指令解析和求值), 但是似乎只做了a+b这件事, 并且除了 PC、 SP 外没有涉及其他的寄存器。 这次实现的 LC-3 虚拟机, 实现了LC-3 指令集, 区别有: 是基于寄存器的, 而不是基于栈的:...

puts "> Crud::before_create" if @crud_options[:log] before_action endNotice that before_create calls a second hook; before_action. This is a generic hook that fires before every crud method's call to save, update or destroy. This means it might be helpful for you to call super when...
The sleep pin, Sleep, is internally pulled low, which puts the board into low-power sleep mode by default. You must drive this pin high to use the board. This can be accomplished with a microcontroller I/O line if you want selective control of sleep mode, or you can make a solder br...
