I am using the K60N512 as a slave device in my project. I am using the IAR development platform. I am using the K60 tower for initial development. I am in the process of getting Interrupt enabled SPI drivers for the K60 and I have looked at MQX 3.7 SPI drivers. (spi_int_dspi.c, spi_int.c). I was also given drivers from the MCF5445. The drivers from the MCF5445 only work with a single SPI interface and they are written for master. Therefore I think my approach will need to utilize the MQX files. We do not want to integrate the MQX into our build so I will have to take these low level driver files files and modify them to work with our interface. When I looked at these files I also believe these are written for master SPI as well. Does anyone know if slave code exists or if there may be a better approach? I am new to SPI and MQX.
