Communication Pipe Service
Xmodem Service
Presentation
The Xmodem service is an application of the communication pipe abstract layer. This layer is
media-independent (USART, USB, etc.) and gives entry points to carry out reads and writes on
an abstract media, the pipe.
The pipe communication structure is a virtual structure that contains all the functions required to
read and write a buffer, regardless of the communication media and the memory management.
The pipe structure defines:
The following structure defines the pipe object:
• a pointer to a communication service structure
• a pointer to a buffer manager structure
• pointers on read and write functions
• pointers to callback functions associated to the read and write functions
typedef struct _AT91S_Pipe
{
// A pipe is linked with a peripheral and a buffer
AT91PS_SvcComm pSvcComm;
