Differences to RL-TCPnet


The following sections describe the changes to the API functions of the Network Component compared to RL-TCPnet, the Real-Time Library provided with MDK Version 4. Previously, there have been two files carrying the header files: rtl.h and net_config.h. This has been unified in MDK-ARM Version 5 to one header file called rl_net.h. The MDK-ARM Version 5 Network Component requires CMSIS-RTOS functionality. Events are no longer called by interrupt service routines which makes the timing of the overall system more predictable.
The API functions along with the differences are shown in the order:
RL-TCPnet: MDK-ARM Version 4 with links to the RL-ARM online manual.
Network Component: MDK-ARM Version 5.
Description of the difference.
Note

• Some API function names are changed to unify the name space of the Software Components.

Changes from rtl.hrtl.h         // Network API for RL-ARM middleware components (MDK-ARM Version 4)rl_net.h      // Complete API for Network Component (MDK-ARM Version 5)MDK Middleware now uses a single header file for the Network Component.
void      init_TcpNet    (void)netStatus net_initialize (void)Return code changed to netStatus.
BOOL  main_TcpNet (void)int   net_main    (void)Return code changed to int.
void  timer_tick (void)removed The function is now replaced by CMSIS-RTOS functionality and therefore no longer required.

• Returns socket handle number or execution status as defined with netStatus.
• Event listening callback function added (must be provided by the user). Refer to net_udp_cb_t.
