Connectivity with USBx


USBX

USBX is Express Logic’s Universal Serial Bus (USB) protocol stack

USBX includes Host, Device, and OTG support

USBX is provided in full source code, is small and fast


USBX Features

Available for host, device and a combination of both

USB low speed, full speed and high speed

Supports all embedded CPUs

Supports many USB host/device and OTG controllers in discrete or IP form integrated with a SOC

OHCI, EHCI, or proprietary like Renesas

Supports most of the standard USB classes drivers

Integrated with Express Logic’s ThreadX, FileX and NetX

Mass Storage, CDC/ECM, RNDIS

SSP Framework


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

Messaging framework

Express Logic NetX™

Express Logic Telnet Application Layer

Module

Provides

Requires


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 e2 studio

Framework

Driver

BSP

X-Ware


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

Application

SF_UART_COMMS

R_SCI_UART

BSP

Requires: sf_comms

Provides: sf_comms

Requires: uart

Provides: uart


Provides: ux_device_class_cdc_acm

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

Application

SF_EL_UX_COMMS

UX_DEVICE_CLASS_CDC_ACM

BSP

Requires: sf_comms

Provides: sf_comms

Requires: ux_device_class_cdc_acm

UX

Provides: ux

Requires: sf_el_ux

Requires: ux

SF_EL_UX

Provides: sf_el_ux


Provides: nx_telnet_server

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

Application

SF_EL_NX_COMMS

NX_TELNET_SERVER

BSP

Requires: sf_comms

Provides: sf_comms

Requires: nx_telnet_server

NX

Provides: nx

Requires: sf_el_nx

Requires: nx

SF_EL_NX

Provides: sf_el_nx


Renesas Synergy™ Configuration Tool


Building Stacks in e2 studio

Select module from “New” dropdown list on Threads tab




Dependency requirements marked with red X

Hover feature shows what dependencies aren’t met






Dependencies met using interface and instance name







Some dependencies met using Properties tab







Some dependencies met using Properties tab

No red X = stack complete


General Usage of SSP

Select Interface and Instance from dropdown list

e2 studio guides you and makes configuration easy

Allocate control and configuration structures

e2 studio generates all of these these based on your configuration

Access API functions through API pointer in Instance structure

e2 studio creates a convenient named Instance pointer

err = my_comms.p_api->write(my_comms.p_ctrl,

&buffer, buffer_size,

TX_NO_WAIT);


Summary

The SSP includes high quality, integrated, tested and production ready software stacks and

modules

SSP framework provides additional well integrated, high level software components

Adding them to your application is easy

Use the E2Studio Synergy configuration tool

Can have a working communications interface within minutes, not days

Still have the flexibility to use the modules (X-Ware, HAL) directly, without going through the

software frameworks, if desired
