模拟SPI部分引脚设置： sbit P24 = P2^4; sbit P25 = P2^5; sbit P26 = P2^6; sbit P27 = P2^7; #define CH376_SPI_SCS P24 /* P14连接CH376的SCS引脚 */ #define CH376_SPI_SDI P25 /* P15连接CH376的SDI引脚 */ #define CH376_SPI_SDO P26 /* P16连接CH376的SDO引脚 */ #define CH376_SPI_SCK P27 /* P17连接CH376的SCK引脚 */

#if 0 #define CH376_SPI_BZ P10 /* P10连接CH376的BZ引脚 */ #endif

#define CH376_INT_WIRE INT0

sbit P35 = P3^5; P35接 RSTI /* RSTI 端口 */ sbit P20 = P2^0; /* SDWP 写保护引脚 */ sbit P21 = P2^1; /* SDINSERT 检测卡插入引脚 */

#define SDWP P20 #define SDINSERT P21 请问大神们，用C8051f120的话，他的端口应该怎么配置，还有RSTI引脚有没必要接

P24,P25,P27设置为输出， P26设置为输入。RSTI根据你的需要选择连接还是不连接，如果你程序中需要复位则连接，否则不连接
