Problems encountered when burning 2812 FLASH
When I am programming the FLASH of 2812 CE, MC/MP is set to 1, SCITXDA=1, but the right half of the programming interface is grayed out and cannot be selected for programming. The encryption interface
Which of these embedded system studies is easier to find a job in Dalian?
I am working on APS.Net and using C#, but I have developed a strong interest in embedded system development and want to switch to this industry. I have looked at C, C++, WinCE, embedded Linux, VxWorks
It's broken. How can I program a laptop without a serial port?
My laptop doesn't have a serial port, so I bought a USB-to-serial cable to write programs to the board. When burning 51 programs, it was fine to connect directly to the 9-pin serial port of the board.
