17 Background: SSP Modules Basic building block of SSP All modules provide an interface Interface is a contract with the user that defines functionality and API Some modules require an interface Examples of modules: Driver code for peripheral Provides Module Requires Messaging framework Express Logic NetX Express Logic Telnet Application Layer 2016 Renesas Electronics Corporation. All rights reserved. Page 17

18 SSP Framework Modules SSP Framework modules are higher level software components Tied to interfaces rather than specific peripheral May use more than one interface Often integrated with ThreadX RTOS (drivers never are) Source code is encrypted, but can be viewed in e 2 studio Framework Driver X-Ware BSP 2016 Renesas Electronics Corporation. All rights reserved. Page 18

19 Framework Example: Communications (UART) Standard communications interface including APIs to open, close, read, write, etc. Can be implemented by an RTOS integrated UART framework UART framework uses SCI Synergy peripheral Requires: sf_comms Provides: sf_comms Requires: uart Provides: uart Application SF_UART_COMMS R_SCI_UART BSP 2016 Renesas Electronics Corporation. All rights reserved. Page 19

20 Framework Example: Communications (USB) Uses the same standard comms interface (open, close, read, write, etc.) Application code does not change Uses USBX CDC ACM device class CDC ACM is a USB device class used to emulate a serial port Requires: sf_comms Provides: sf_comms Application SF_EL_UX_COMMS Requires: ux_device_class_cdc_acm Provides: ux_device_class_cdc_acm UX_DEVICE_CLASS_CDC_ACM Requires: ux Provides: ux Requires: sf_el_ux Provides: sf_el_ux UX SF_EL_UX BSP 2016 Renesas Electronics Corporation. All rights reserved. Page 20

21 Framework Example: Communications (Telnet) Uses the same standard comms interface (open, close, read, write, etc.) Application code does not change Uses NetX Telnet server Telnet is a session layer protocol used to emulate a terminal Requires: sf_comms Provides: sf_comms Application SF_EL_NX_COMMS Requires: nx_telnet_server Provides: nx_telnet_server Requires: nx Provides: nx NX_TELNET_SERVER Requires: sf_el_nx Provides: sf_el_nx NX SF_EL_NX BSP 2016 Renesas Electronics Corporation.
