谁用MCC配置过SPI啊？分享一下经验，初始化函数看不懂啊。
- bool SPI1_Open(uint8_t spiConfigIndex)
- {
- bool returnValue = false;
- if(false == SPI1CON0bits.EN)
- {
- SPI1CON0 = spi1_configuration[spiConfigIndex].con0;
- SPI1CON1 = spi1_configuration[spiConfigIndex].con1;
- SPI1CON2 = spi1_configuration[spiConfigIndex].con2 & ~(_SPI1CON2_SPI1RXR_MASK) & ~(_SPI1CON2_SPI1TXR_MASK);
- SPI1BAUD = spi1_configuration[spiConfigIndex].baud;
- SPI1CLK = spi1_configuration[spiConfigIndex].clksel;
- TRISBbits.TRISB4 = 0;
- SPI1CON0bits.EN = 1U;
-
- returnValue = true;
- }
- else
- {
- returnValue = false;
- }
- return returnValue;
- }
配置好后这么操作
SPI1_Initialize();
while(SPI1_Open(SPI1_DEFAULT)==false);
发现没反应啊，卡这走不下去。
