我在阅读CYRF69213的范例
在main.c中出现：
#pragma ioport EP0_DR0: 0x050 // Endpoint 0 Data Register 0
BYTE EP0_DR0;
#pragma ioport EP0_DR1: 0x051 // Endpoint 0 Data Register 1
BYTE EP0_DR1;
#pragma ioport EP0_DR2: 0x052 // Endpoint 0 Data Register 2
BYTE EP0_DR2;
#pragma ioport EP0_DR3: 0x053 // Endpoint 0 Data Register 3
BYTE EP0_DR3;
#pragma ioport EP0_DR4: 0x054 // Endpoint 0 Data Register 4
BYTE EP0_DR4;
#pragma ioport EP0_DR5: 0x055 // Endpoint 0 Data Register 5
BYTE EP0_DR5;
#pragma ioport EP0_DR6: 0x056 // Endpoint 0 Data Register 6
BYTE EP0_DR6;
#pragma ioport EP0_DR7: 0x057 // Endpoint 0 Data Register 7
BYTE EP0_DR7;
在lpradio.h文件中出现：
#pragma fastcall16 RadioReset
#pragma fastcall16 RadioRead
#pragma fastcall16 RadioWrite
#pragma fastcall16 RadioSetPtr
#pragma fastcall16 RadioSetLength
#pragma fastcall16 RadioFileRead
#pragma fastcall16 RadioFileWrite
#pragma fastcall16 RadioBurstRead
#pragma fastcall16 RadioBurstWrite
#pragma fastcall16 RadioSetFrequency
#pragma fastcall16 RadioSetChannel
#pragma fastcall16 RadioGetFrequency
#pragma fastcall16 RadioGetChannel
#pragma fastcall16 RadioSetTxConfig
#pragma fastcall16 RadioGetTxConfig
#pragma fastcall16 RadioSetXactConfig
#pragma fastcall16 RadioGetXactConfig
#pragma fastcall16 RadioSetFrameConfig
#pragma fastcall16 RadioGetFrameConfig
#pragma fastcall16 RadioSetThreshold32
#pragma fastcall16 RadioGetThreshold32
#pragma fastcall16 RadioSetThreshold64
#pragma fastcall16 RadioGetThreshold64
#pragma fastcall16 RadioSetPreambleCount
。。。。。。
请问，在与处理命令#pragma之后的的特征字符串“ioport”和“fastcall16”表示什么意思？
#pragma ioport EP0_DR0: 0x050 // Endpoint 0 Data Register 0
BYTE EP0_DR0;
这条命令似乎还有别的作用，请是否有，是什么啊？
谢谢 |
