PDxxSIM I/O DLL Kit

 

 

The PDxxSIM I/O DLL kit is supported by the following simulator debuggers :

• M3T-PD32RSIM V.2.00 Release 1 or later
• M3T-PD308SIM V.3.00 Release 2 or later (Discontinued product)
• M3T-PD30SIM　V.5.00 Release 1 or later (Discontinued product)

Note: For the High-performance Embedded Workshop environment, use the I/O DLL Kit.

Overview

The PDxxSIM I/O DLL kit provides a means for extending the functions of the M3T-PDxxSIM simulator debugger. This kit supports the creation of I/O DLLs.

The I/O DLL refers to a DLL* that operates in cooperation with the simulator engine of the M3T-PDxxSIM.

Once the necessary settings are made, the M3T-PDxxSIM allows you to load an I/O DLL and operate it synchronously with the timing at which instructions are single-stepped, memory is read or written or an interrupt occurs. That way, the operation of the input/output ports or the internal peripheral functions of the microcomputer can be simulated as a means of debugging the target program. Furthermore, linked operation with an external tool can be realized by, for example, sending and receiving data to and from that tool.

Any desired I/O DLL can be created by using C/C++ language. To create an I/O DLL, you need to have Microsoft Visual C++, a Windows application development environment available on the market.

*DLL is the acronym of Dynamic Link Library. This is a function of the operating system that allows you to save executable routines (routines that supply a specific function or a set of functions) to be saved separately as a file with the extension ".dll". These routines are loaded only when they are needed by the calling program.

Development Background

The M3T-PDxxSIM simulator debugger is capable of debugging in the absence of a user target. However, peripheral I/O simulations of input/output ports, A/D conversion and interrupts are not supported. The M3T-PDxxSIM supports an I/O simulation function to assist you in debugging a program that accesses the peripheral I/O. Use of this function enables you to simulate input/output to and from I/O ports, generation of interrupts and the operation of peripheral I/Os such as timers and A/D converters.

However, complicated I/O simulations cannot be realized unless they are written in an I/O script. I/O scripts had a problem that they need to be written in an original script language, which is difficult to learn.

To solve this and other problems, we have developed an I/O DLL function that allows you to define I/O simulations by using Visual C++ from Microsoft Corporation.

Development Tools Used

To create an I/O DLL, you need to have Microsoft Visual C++, a Windows application development environment available on the market.

Operating Environment

Depends on the operating environment of the M3T-PDxxSIM used. Refer to the release note for each product for details about the operating environment of the M3T-PDxxSIM.

Sample Programs

The sample programs are stored in a location at the hierarchical level below the directory in which the PDxxSIM I/O DLL kit is installed (e.g., below c:\mtool\idoll\samples). Refer to the release note for details on how to install the PDxxSIM I/O DLL kit.

Sample Programs
