我可以在微芯片和谐框架中模拟pic 32 usart-static-wf32示例吗？

你必须在模拟器中注入接收值。检查模拟器帮助-刺激-注册表注入-消息触发器

    You have to inject receive values into the simulator.  Check out simulator help - stimulus - register injection - message trigger

嗨，乔治，谢谢你给我的建议，现在我可以用注册表注入我收到的数据。我有一个关于SPI的问题，一旦我收到了USAT字节，我想初始化SPI并用SPI发送数据，打开连接到我的另一个模块的LED。IC32。请看一下下面的代码，并建议这是正确的方法。也可以使用寄存器注入来模拟SPI吗？另一件事，如果我使用上面的代码SPI，我的程序总是困在下面的while循环在系统初始化。你能告诉我问题是什么吗？

    Hi George,
 
Thank you for the suggestion I looked into it and now I am able to receive the data I sent using register injection.
I have another question regarding SPI once I have received the usart byte I want to initialize SPI and send data using SPI to turn on led of another module connected to my Pic32. Can you please have a look at my code below and suggest if this is the proper way to go about it. And also can I simulate SPI also using Register injection? 
 
case APP_STATE_URX4: // USART receive state
        {
            if (!DRV_USART0_ReceiverBufferIsEmpty())
            {
               appData.rx4_byte = DRV_USART0_ReadByte(); // read received byte
if (appData.rx4_byte == 0b00001010)
               {
appData.state = APP_STATE_SPI_INIT; // change state to SPI
             }
}
            break;
        }

case APP_STATE_SPI_INIT:
{
if (DRV_SPI_STATUS(sysObj.spiObjectIdx0) == SYS_STATUS_READY) //Open SPI
{
appData.SPI_Handle = DRV_SPI_Open(DRV_SPI_INDEX_1, DRV_IO_INTENT_READWRITE);
}

if (appData.SPI_Handle != DRV_HANDLE_INVALID)
{
appData.state = APP_STATE_SPI_WRITE_LEC_IC;
}

break;
}

case APP_STATE_SPI_WRITE_LED_IC:
{
SPI_CSOn(); // Assert SPI Chip Select
SPI_Write_Buffer_Handle = DRV_SPI_BufferAddWrite2();
appData.state = APP_STATE_LED;
break;
}
 
Another thing if i use the above code for  SPI my program is always stuck in the below while loop at system initialization. Can you please tell me what the problem might be?
 

PLIB_TEMPLATE void SPI_BufferClear_Default( SPI_MODULE_ID index )
{
spi_registers_t volatile * spi = ((spi_registers_t *)(index));
uint32_t dummy = 0u;
/* For enhanced buffer mode, Read the SPIxBUF till RX FIFO gets empty */
if(1u == spi->SPIxCON.ENHBUF)
{
while(0u == spi->SPIxSTAT.SPIRBE)
{
/* Read the SPIxBUF to flush it */
dummy = spi->SPIxBUF;
}
