What should I do if the 51 SCM board cannot find the device in keil

Before I encountered this problem, I downloaded fiveorsix versions KEIL Want to find the corresponding version with STC15F2K60S2 Chip , But downloading and installing many versions is not enough , I also found many solutions on the Internet , But most of them are MDK Of PACK download , Until one day I saw STC—ISP There is a very convenient STC Emulator

utilize STC_ISP Just choose KEIL Installation directory

Then you can insert it successfully

restart KEIL Can be in Option It's inside
