RX Smart Configurator User's Guide: e² studio

1. Overview

1.1 Purpose

This application note describes the basic usage of the Smart Configurator and the e² studio integrated development environment, including the procedure for creating a project.

Refer to the User’s Manual of the e² studio for how to use the e² studio.

1.2 Features

The Smart Configurator is a utility for combining software to meet your needs. It handles the following three functions to support the embedding of drivers from Renesas in your syste ms: importing middleware in the form of FIT (Firmware Integration Technology) modules, generating driver code, and making pin settings.

1.3 Software Components

The Smart Configurator supports two types of software components: Code Generator (CG) and Firmware Integration Technology (FIT). Drivers and middleware supported by each software type are:

• Basic drivers:

• CG drivers (CMT, A/D Converter, SCI, etc.)

• FIT modules (CMT, DTC, DMAC, RSPI, SCIFA, etc.)

• Middleware:

• FIT modules (USB, Ethernet, Flash Memory (programming the on-chip flash memory), etc.)

The basic driver is a control program for peripheral functions of microcomputer such as CMT, A/D converter, SCI, etc. It is convenient to embed a software component (CG driver or FIT module) using code generation function. In addition, FIT modules can be embedded for using middleware such as USB, Ethernet, and Flash memory (programming the on-c hi p flash memory) as software components.

6.3 Initializing Clocks

Configurati ons of the clock source selected in the [Clocks] page are generated to the macros in the r_bsp_config.h file located in ¥src¥smc_gen¥r_config folder. Clock initialization codes wi ll be handled by r_bsp before entering main().

The r_bsp_config.h file also contains other MCU related settings (e.g. package, stack size).

Configurations of other clocks are generated in ¥src¥smc_gen¥general folder.

7. Creating User Programs

The Smart Configurator handles two component types, [Firmware Integration Technology] and [Code Generator], with each requiring different methods to add custom code to the output source files. This section describes the methods to add custom code for both components.

7.1 Adding Custom Code in the Case of Firmware Integration Technology (FIT)

When [Firmware Integration Technology] is selected as the component type, the configuration options are set in r_xxx_config.h in the folder r_config. For the settings of the configuration options, refer to the application note (in the doc folder) on the FIT module (r_xxx) which yo u ha ve added to the project tree.

If the target file already exists, the existing contents of the file are protected when source code is output.

RX Smart Configurator User's Guide: e² studio

/* Start user code for xxxx. Do not edit comment generated here */

7.2 Adding Custom Code in the Case of Code Generator

When [Code Generator] is selected as the component type, if files which have the same name already exist, new code will be merge d only with the existing cod e that is b e tween the comments below.

/* End user code. Do not edit comment generated here */

In the case of [Code Generator], three files are generated for each of the specified peripheral functions. The file names are “Config_xxx.h”, “Config_xxx.c”, and “Config_xxx_user.c” as the default, with “xxx” representing the name of the peripheral module. For example, “xxx” will be “CMT3” for the compare-match timer (resource CMT3). The comments to indicate where to add custom code are at the start and end of each of the three files. Comments to indicate where to add user code are also added to the interrupt function for the perip heral module corresponding to Config.xxx_user.c. The following examples are for CMT3 (Config_CMT3_user.c).

General Precautions in the Handling of Microprocessing Unit and Microcontroller Unit Products

The following usage notes are applicable to all Microprocessing unit and Microcontroller unit products from Renesas. For detailed usage notes on the products covered by this document, refer to the relevant sections of the document as well as any technical updates that have been issued for the products.

1. Precaution against Electrostatic Discharge (ESD)

A strong electrical field, when exposed to a CMOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop the generation of static electricity as much as possible, and quickly dissipate it when it occurs. Environmental control must be adequate. When it is dry, a humidifier should be used. This is recommended to avoid using insulators that can easily build up static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work benches and floors must be grounded. The operator must also be grounded using a wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions must be taken for printed circuit boards with mounted semiconductor devices.

2. Processing at power-on

The state of the product is undefined at the time when power is supplied. The states of internal circuits in the LSI are indeterminate and the states of register settings and pins are undefined at the time when power is supplied. In a finished product where the reset signal is applied to the external reset pin, the states of pins are not guaranteed from the time when power is supplied until the reset process is completed. In a similar way, the states of pins in a product that is reset by an on-chip power-on reset function are not guaranteed from the time when power is supplied until the power reaches the level at which resetting is specified.

3. Input of signal during power-off state

Do not input signals or an I/O pull-up power supply while the device is powered off. The current injection that results from input of such a signal or I/O pull-up power supply may cause malfunction and the abnormal current that passes in the device at this time may cause degradation of internal elements. Follow the guideline for input signal during power-off state as described in your product documentation.

4. Handling of unused pins

Handle unused pins in accordance with the directions given under handling of unused pins in the manual. The input pins of CMOS products are generally in the high-impedance state. In operation with an unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of the LSI, an associated shoot-through current flows internally, and malfunctions occur due to the false recognition of the pin state as an input signal become possible.

5. Clock signals

After applying a reset, only release the reset line after the operating clock signal becomes stable. When switching the clock signal during program execution, wait until the target clock signal is stabilized. When the clock signal is generated with an external resonator or from an external oscillator during a reset, ensure that the reset line is only released after full stabilization of the clock signal. Additionally, when switching to a clock signal produced with an external resonator or by an external oscillator while program execution is in progress, wait until the target clock signal is stable.

6. Voltage application waveform at input pin

Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the CMOS device stays in the area between V (Max.) and V input level is fixed, and also in the transition period when the input level passes through the area between V

7. Prohibition of access to reserved addresses

Access to reserved addresses is prohibited. The reserved addresses are provided for possible future expansion of functions. Do not access these addresses as the correct operation of the LSI is not guaranteed.

8. Differences between products

Before changing from one product to another, for example to a product with a different part number, confirm that the change will not lead to problems. The characteristics of a microprocessing unit or microcontroller unit products in the same group but having a different part number might differ in terms of internal memory capacity, layout pattern, and other factors, which can affect the ranges of electrical characteristics, such as characteristic values, operating margins, immunity to noise, and amount of radiated noise. When changing to a product with a different part number, implement a systemevaluation test for the given product.

(Min.) due to noise, for example, the device may malfunction. Take care to prevent chattering noise from entering the device when the
