struct Crybus::Connector::Segment

• Crybus::Connector::Segment
• Struct
• Value
• Object

Overview

An address chunk assigned to this connector.
Each segment takes up a portion of address space
and has an individual output and input proc (function pointer).

Segments can act as either one connection to the bus or a chain of connections which would function similarly to IO registers, with each segment having a seperate output and input proc based of what that register should do when being read/written.

Defined in:

cry-bus/connector.cr

Constructors

• .new(start_adr : UInt32, length : UInt32, seg_out : Proc(UInt32, UInt8), seg_in : Proc(UInt32, UInt8, Nil))

  Creates a new segment given its start address, size, and IO procs.

• .new(start_adr : UInt32, seg_out : Proc(UInt32, UInt8), seg_in : Proc(UInt32, UInt8, Nil))

  Creates a new segment given its start address and IO procs.
  end_adr is set to start_adr + 1

Instance Method Summary

• #end_adr : UInt32

  The address in which the bus will no longer see this segment

• #seg_in : Proc(UInt32, UInt8, Nil)

  The function for when the segment is called to input.
  Takes an address and the 8 bit data

• #seg_out : Proc(UInt32, UInt8)

  The function for when the segment is called to output.
  Takes an address.

• #start_adr : UInt32

  The address in which the bus will begin to see this segment

• #would_hit?(address : UInt32) : Bool

  Returns whether or not an address is within this segments address space
