}
错误现象是
Build target 'Target 1'
compiling ZQL_nvic.c...
..\src\ZQL_nvic.c(62): error: #20: identifier "UART4_IRQn" is undefined
..\src\ZQL_nvic.c: NVIC_InitStructure.NVIC_IRQChannel = UART4_IRQn;
..\src\ZQL_nvic.c: ^
..\src\ZQL_nvic.c(69): error: #20: identifier "UART5_IRQn" is undefined

麻烦高手大虾帮忙解决一下 |
