显示屏为原子4342 RGBLCD4.3寸屏

目前问题与硬件无关，实验14 LTDC LCD（RGB屏）实验  在KEIL5下编译时出现问题：
Rebuild target ' LTDC LCD'
compiling main.c...
main.c: Error: C9580E: CT.Compiler5 is not supported by this product
Product: MDK-ARM Lite 5.10
Component: ARM Compiler 5.06 update 2 (build 183)
Tool: ArmCC [4d35cd]
"..OBJLTDC LCD.axf" - 1 Error(s), 0 Warning(s).
Target not created


请问是编译器不对吗？或者keil5的设置设置好？
