有谁用过CC2530的SPI，通过W5500联以太网？
P1_3 ------ RST
P1_4-------CS
p1_5 ------CLK
p1_6 ----MOSI
p1_7 -----MISO
WIZ_SPI_Init(){
CLKCONCMD = 0x80; while (CLKCONSTA != 0x80); // 32MHz
PERCFG |= 0x02; // PERCFG.U1CFG = 1
P1SEL |= 0xE0; // P1_7, P1_6, and P1_5 are peripherals
P1SEL &= ~0x10; // P1_4 is GPIO (SSN) SPI_CS
P1DIR |= 0x10; // SSN is set as output
// Set baud rate to max (system clock frequency / 8)
U1BAUD = 0x00; // BAUD_M = 0
U1GCR |= 0x11; // BAUD_E = 17
U1CSR &= ~0xA0; // SPI Master Mode
// Configure phase, polarity, and bit order
U1GCR &= ~0xC0; // CPOL = CPHA = 0
U1GCR |= 0x20; // ORDER = 1
P1SEL &= ~0x08; // P1_3 is GPIO (SSN)
P1DIR |= 0x08; // P1_3 is set as output
}
以下是主调用：
WIZ_SPI_Init();
Load_Net_Parameters(); //装载网络参数
W5500_Hardware_Reset(); //硬件复位W5500
W5500_Initialization(); //W5500初始货配置
W5500_Socket_Set(); //W5500端口初始化配置
W5500_Interrupt_Process(); //W5500中断处理程序框架
但是ping不通，有没有知问题在那里？
