Overview

QE for USB is a tool for embedded software development currently supports system development involving the USB modules of RX family and RL78 family devices. It eases the debugging of USB systems, shortening development periods and lowering costs.

By expanding the existing integrated development environment (IDE), it will help in resolving problems in development for systems which use the USB such as :
"How do I actually include the USB in my embedded application?"
"It seems the USB is not connecting even though I've included the code."

This product is a plug-in which extends the Renesas IDE "e² studio". You can download and utilize it free of charge.

Functions

View transitions of the USB state at a glance: [USB State Chart (QE)] view

A state chart of the USB connection (enumeration) process is displayed in real-time. As well as confirming the success of connection, the user can visually check the state and timing where processing stopped when connection has failed, which enables a problem to be quickly solved.

[USB State Chart (QE)] view

The registers to be set are listed, and pop-up messages indicate errors in settings: [USB Setting Registers (QE)] view

The register values and descriptions related to the settings for USB connection are indicated. If a register is not set to a correct value needed for connection, it is marked "NG" (no good) and the user can find problems simply by opening this view. For some MCUs, the tool also supports another feature where placing the mouse cursor over a register value in the view pops up a message with the meaning of the value so the user can see how to correct the setting.

[USB Setting Registers (QE)] view

Check the settings for USB descriptors in a dedicated list: [USB Descriptors (QE)] view

This is a list of the descriptor values and states which are set in the process of USB connection (enumeration). If the value of a descriptor is incorrect, it is marked "NG". A single-click on an "NG" location will cause a jump to the corresponding source code so the user can immediately edit it.

[USB Descriptors (QE)] view

Rapidly activated communications monitoring tool: [Simplified Protocol Analysis (QE)] view (Note1)

This feature activates the free and open "Wireshark" protocol analyzer, in this case for the monitoring of USB communications. Contents of USB connection can be checked through this view. To use this feature, "Wireshark" and "USBPcap", a free packet capture software tool, should also be installed.

[Simplified Protocol Analysis (QE)] view

Note

  1. [Simplified Protocol Analysis (QE)] view supports Wireshark V1.12.10. This view does not support latest Wireshark. For Wireshark version 2 or later, it can monitor USB communication by itself.
