I use PDA to connect to Access database in VS2003. I wrote a small program. When I run it, it always prompts that an unhandled "System.IO.FileNotFoundException" type exception occurred in InTheHand.Ad...
1 Please see if my understanding is correct: After executing setvect(0x1c,func1), the main function is interrupted and the func1 function is executed instead. 2 How many times does the func1 function ...
I. PrefaceRecently, I was honored to get a GD32VF103C-START development board from Chuangyi Stack. It is a 32-bit general-purpose microcontroller based on the RISC-V core. From this website, I have a ...
I'm developing a project recently that requires the use of STM32F205. This is my first time using STM32, and everything was done under the guidance of my colleagues. Since I don't use STM32 very much,...
I modified the httpdisk code and changed it to: 1. After communicating with the server program, it is virtualized into the entire logical hard disk. It seems to have passed and no problems were found....
