    A complete set of bit banged, software driven I2C routines I created for any PIC device - and they work!! These functions are single Master only functions, and are ideal for communicating with things like EEPROMs, LCD Drivers, ADC Converters etc

    VHDL實(shí)現(xiàn)SPI功能源代碼 -- The SPI bus is a 3 wire bus that in effect links a serial shift -- register between the "Master" and the "slave". Typically both the -- Master and slave have an 8 bit shift register so the combined -- register is 16 bits. When an SPI transfer takes place, the Master and -- slave shift their shift registers 8 bits and thus exchange their 8 -- bit register values.

    An AHB system is made of Masters slaves and interconnections. A general approach to include all possible "muxed" implementation of multi layered AHB systems and arbitrated AHB ones can be thought as an acyclic graph where every source node is a Master, every destination node is a slave and every internal node is an arbiter there must be one and only one arc exiting a Master and one or more entering a slave (single slave verus multi-slave or arbitrated slave) an arbiter can have as many input and output connections as needed. A bridge is a special node that collapses one or more slave nodes and a Master node in a new "complex" node.
