3) Modify the Makefile file in the u-boot directory. Find the place where smdk6400_config is found, and under it, create the compilatio...
Different pins of the same group of io ports of stm32 are set to different input and output modes. For example, PA1 of PA port is used as input to read input value, and PA2 is used as output to output...
1. First find the project file in Z-stack Home 1.2.2 that you want to modify, the project file with .ewd .ewp .eww as the suffix (in fact, these three files can be opened with a TXT editor. If you kno...
After connecting to the experimental board, debug--connect prompted an error, so I pressed the power connector and heard a crash. What happened? Is the board burnt?...
RS-485 Network Troubleshooting Despite the increasing availability of more modern alternatives, RS-485 technology remains a mainstay in countless communications networks. Here is an 8-step method for ...
introduction
In the discharge process of tokamak plasma physics, the study of rupture and sawtooth is of great significance. Rupture and sawtooth exist in most tokamaks. Rupture is a notew...[Details]
