Hi Friends, Im a newbie to LPC. Currently i am working on a project which requires me to interface the LPC2214 chip with MSC1210 using SPI, and is proving to be very problematic. In both the below cases i have tried debugging using JTAG. Case 1 I have tried with LPC as a Master and also connected the SS- pin to High. Here, the transmission from LPC to MSC is perfectly fine, and also the reception of bytes at MSC is perfect, but the MSC Tx i.e. slave output doesnot respond at all. The MSC doesnot shift the data out from its SPIData register on receiving the clock from the master. STRANGE!!!!! na Case 2 Having tried the above, i then tried with the MSC as master and LPC as slave. Here the things are even interesting. I am able to transfer data both ways. But the data received at the Slave i.e MSC, doesnot match the data which was sent by the Master. However, the data is received in correctly at the Master end. The data was verified using UART's on both the controllers. I hope some one has tried this and will be able to help me out. Its been over 2 weeks now that i have been struggling with this problem. Is there any compatibility issues between the LPC2214 and MSC1210. Regards, Jerome
