[align=left][font=宋体][size=11.5pt] [/size][/font][/align][align=left][font=宋体][size=11.5pt]Some people say that for multilayer boards, all signal lines should be routed on the inner layer. Is this tru...
Many main control chips have timers. The use of timers is nothing more than setting a timer, generating an interrupt when the time is up, and then doing something in the interrupt. If you follow this ...
I received the board on August 14, 2015. Here’s a quick picture:The design of the core board of the board is really lamentable. When you press a button, the core board will sway slightly, haha!...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
