* README.md - Add new readme indicating that this host program is only intended for the stream-based demo, and explaining how to use it * host.adb - Add much more comments in the header block explaining how to use this program and why it is needed - Parameterize the host port number instead of hard-coding it * demo_serial_port_blocking.adb - Use normalized (new) procedure names for Send and Receive, for consistency with other versions - Add comments re: baud rate and other settings required * demo_serial_port_nonblocking.adb - Better name for local procedure - Add many more comments re: settings * demo_serial_port_streaming.adb - Replace source code in comment header block with location of the actual code and project file. - Add comment re: serial port settings * peripherals_blocking.ads - Peripheral should be a constant - COM can now reference the designated USART, the component of Peripheral * peripherals_nonblocking.ads - Same as for peripherals_blocking.ads * peripherals_streaming.ads - Same as for peripherals_blocking.ads * serial_io-blocking.ads - Type Serial_Port now designates a USART rather than type Peripheral - No longer provide call through routines for the Serial_IO package's Initialize_Hardware and Configure since client can easily call them. Better separation of concerns as a result. - Change signatures of internal routines to be access-to-USART * serial_io-blocking.adb - Internal simplifications reflecting change to access discriminant now designating type USART - Remove code for Initialize_Hardware and Configure, per removal from package spec * serial_io-nonblocking.ads - Type Serial_Port now designates a USART rather than type Peripheral - No longer provide call through routines for Serial_IO packages Initialize_Hardware and Configure since client can easily do so, and simplifies this package - Change signatures of internal routines to be access-to-USART * serial_io-nonblocking.adb - Internal simplifications reflecting change to access discriminant now designating type USART - Remove code for Initialize_Hardware and Configure, per removal from package spec - Use short-circuit control forms in ISR since don't need to check both conditions, should be a little faster * serial_io-streaming.ads - Type Serial_Port now designates a USART rather than type Peripheral - No longer provide call through routines for Serial_IO packages Initialize_Hardware and Configure since client can easily do so, and simplifies this package - Change signatures of internal routines to be access-to-USART * serial_io-streaming.adb - Internal simplifications reflecting change to access discriminant now designating type USART - Remove code for Initialize_Hardware and Configure, per removal from package spec * serial_io.ads - Procedure Initialize_Hardware's formal parameter is no longer an access parameter - Procedure Configure's first formal parameter is now access to USART * serial_io.adb - Change to prcoedures' signatures as per spec - Procedure Configure now uses distinguished receiver syntax for USART routines, much cleaner
