標題: cc2530f256 單片機 IAR編譯器能編譯，unsigned long 類型為什么
使用的是CC2530F256 ZigBee的單片機，因為需要讀字庫芯片 GT21L16S2W ,而給字庫芯片發送的地址是24位的地址需要用長整型 unsigned long 類型；但是IAR編譯器能正常編譯通過，又是按照unsigned int 類型在跑。而且也無法有bit 位的定義為什么IAR編譯器只能到達16位而不能達到32位 本人用的是CD-EW8051-8101 51 版本編譯器

如下程序：
#define SI P0_4
#define CLK P0_5
#define SO P0_6
#define CS P0_7

#define CS_L do {CS = 0;}while(0)
#define CS_H do {CS = 1;}while(0)
#define SI_L do {SI = 0;}while(0)
#define SI_H do {SI = 1;}while(0)
#define CLK_L do {CLK= 0;}while(0)
#define CLK_H do {CLK= 1;}while(0)

P0SEL &= ~0x10; // P0_4
 P0DIR |= 0x10;
 P0INP &= ~0x10;

P0SEL &= ~0x20; // P0_5 sck
 P0DIR |= 0x20;
 P0INP &= ~0x20;

P0SEL &= ~0x40; // P0_6 輸入
 P0DIR &= ~0x40;
 P0INP &= ~0x40;

P0SEL &= ~0x80; // P0_7 cs
 P0DIR |= 0x80;
 P0INP &= ~0x80;

void SendByte(uint32 cmd)
{
 unsigned char i;
 cmd=cmd|0x03000000;
 for(i=0;i<32;i++)
 {
 CLK_L;
 if(cmd&0x80000000)
 SI_H;
 else
 SI_L;
 CLK_H;
 cmd=cmd<<1;
 }
}

unsigned char ReadByte(void)
{
 unsigned char i;
 unsigned char dat=0;
 CLK_H;
 for(i=0;i<8;i++)
 {
 CLK_L;
 dat=dat<<1;
 if(SO)
 dat=dat|0x01;
 else
 dat&=0xfe;
 CLK_H ;
 }
 return dat;
}

unsigned char r_dat_bat(uint32 address,unsigned char byte_long,unsigned char *p_arr)
{
 unsigned int j=0;
 CS_L;
 SendByte(address);
 for(j=0;j
 {
 p_arr[j]=ReadByte();
 }
 CS_H;
 return p_arr[0];
}

void gt_16_GetData (unsigned char MSB, unsigned char LSB, unsigned char* DZ_Data)
{
uint32 BaseAdd=0,Address;
if(MSB == 0xA9 && LSB >=0xA1)
Address = (282 + (LSB - 0xA1))*32+BaseAdd;
else if(MSB >=0xA1 && MSB <= 0xA3 && LSB >=0xA1)
 Address =( (MSB - 0xA1) * 94 + (LSB - 0xA1))*32+ BaseAdd;
else if(MSB >=0xB0 && MSB <= 0xF7 && LSB >=0xA1)
 Address = ((MSB - 0xB0) * 94 + (LSB - 0xA1)+ 846)*32+ BaseAdd;
r_dat_bat(Address,32,DZ_Data);
}

gt_16_GetData(0xC7,0xE9,WZ_Data);

注：0xC7,0xE9 是內碼 WZ_Data保存32字節的點陣
