I have a existing motherboard with coldfire MCF5307 processor with RTOS MQX 2.4.0. I want to add USB OTG application and for this PIC controller is being choosen (USB stack is available).
I wont be using parallel port ( because it is being used by other peripheral) or serial port. I have decided to use 8 bit data bus for the communication between MCF5307 and PIC32(it will be configured as PSP mode for the communication).
Here i am attaching image file which depicts hardware interface.
I need firmware help. Does anybody have experience of developing firmware for the same application.
Can i get sample code for the same??
Your help shall be highly apprecitaed.
