问题解决了。这个问题是在我的EEPROM内存调用中运行的DAC芯片选择CS。这损坏了我的内存数据。简单的代码位解决了PIC32、MPLAB 3.45、和声1.06(我也使用和声驱动……DRVYSST25VF020B用于EEPROM芯片)。我有一个SPI1 WI实例。第3个客户端,所有在动态模式下,用下面的代码打开句柄://StuteNeNordLe1= DAC芯片/sSpMeNeDeNeLe2= SPI温度计//StuteNeNeDeLe3=EEPROM存储器CHIPsStuteNoReLe1= DRVYSST25VF020BYOPEN(DRVYSST25VF2020BXIDEXOR0 0,DRVIIOION ITENtiN Read Wrrad DRVIOION ITENTIN非阻塞DRVYIIOI).SpEntHANDLe2= DRVYSST25VF020BYOPEN(DRVYSST25VF20BI索引X0,DRVIIOION EntEntRead Wrad DRVIIOION EntIn非阻塞DRVVIOION ITENTIN共享);StEngHANDURL3= DRVYSST25VF020BYOPEN(DRVYSST25VF2020BXIDEXX0 0,DRVIIOION EntEntRead Wrrad DRVIIOION EntIn非阻塞DRVVIOION ITEN共享)智能共享除了DAC和ErpOM芯片之间存在干扰之外,所有的工作都有。当我把数据写入EEPROM芯片保存并读取它时,数据每次都会被轻微地破坏,例如,我写下“我走狗”的字符串。当我读到这篇文章的时候,我得到了“我的狗”。当我禁用DAC时,内存写的工作正常。我如何阻止SPI的实例相互干扰?我试过的东西…我试着减慢SPI时钟…没有Goodii尝试& DrvyIOION EntEngBull≫and lt;DrvyIoItIntIn独家& Gt;…不好。

This was corrupting my memory data. simple bit of code solved this Pic32, mplab 3.45, hARMony 1.06 (I am also using the harmony driver...DRV_SST25VF020B for the eeprom chip ) I have one instance of SPI1 with 3 clients , all in dynamic mode I open the handles with the following code: //sstOpenHandle1 = DAC chip //sstOpenHandle2 = SPI Thermometer //sstOpenHandle3 = EEPROM memory chip sstOpenHandle1 = DRV_SST25VF020B_Open(DRV_SST25VF020B_INDEX_0, DRV_IO_INTENT_READWRITE | DRV_IO_INTENT_NONBLOCKING | DRV_IO_INTENT_SHARED ); .sstOpenHandle2 = DRV_SST25VF020B_Open(DRV_SST25VF020B_INDEX_0, DRV_IO_INTENT_READWRITE | DRV_IO_INTENT_NONBLOCKING | DRV_IO_INTENT_SHARED ); sstOpenHandle3 = DRV_SST25VF020B_Open(DRV_SST25VF020B_INDEX_0, DRV_IO_INTENT_READWRITE | DRV_IO_INTENT_NONBLOCKING | DRV_IO_INTENT_SHARED ); I have everything working except that there is interference between the DAC and the EERPOM chip. When I write data to the eeprom chip to save it and read it back ,, the data is slightly corrupted, in a random way each time. For example , I write the string "I walk the dog" . When I read this back I get something like, "I y thy dog". When I disable the DAC, the memory writes work correctly.. How do I stop the instances of the SPI interfering with each other? Things I tried... I tried slowing down the SPI clock..no good I tried |
