有時候我們需要在MDK中忽略掉某一個具體的warnning,怎么做呢？
只需在Misc Control中添加 “--diag_suppress=<num>” 就可以了， num就是Keil中的警告代碼，，比如在工程中需要忽略..\..\..\..\src\drivers\gpio\gpio.h(169): warning: #61-D: integer operation result is out of range 這個警告，只需添加 --diag_suppress=61，如下圖所示：
我自己的截圖：
..\Bsp\DAC8562\dac8562.c(307): warning: #177-D: variable "cmd" was declared but never referenced
..\App\global\global.c(102): warning: #69-D: integer conversion resulted in truncation——這里沒有屏蔽
testValue = 0xaacc;
..\App\global\global.c(73): warning: #550-D: variable "addr" was set but never used
uint32_t addr = 0;
..\Bsp\IO_driver\IO_driver.c(1699): warning: #188-D: enumerated type mixed with another type
