- GuideDescribes the RX products migration map, which shows the relationship between previous-generation products and new-generation products, and the preparation status of difference documents, which summarize the functional differences between each RX product. Please use this application note to gather information when migrating from previous-generation products to new-generation products or when using different RX products.

- Application NoteAI-generated Summary: The document details the Renesas CAN Controller's usage, including compatibility, evaluation results, and principles of pretended networking. It covers sample software descriptions, CAN driver functionalities such as initialization, configuration, transmission, reception, and diagnostics. The text also explains mapping of lower CAN drivers, application examples, and frequently asked questions addressing CAN conformance, transceiver issues, bit timing, operation modes, power save modes, transmission, reception, message storage, peripheral bus access, and interrupt handling.

- Application NoteAI-generated Summary: The document explains key compiler option differences when migrating source code from the SuperH family to the RX family. It highlights that char types default to signed in SuperH but unsigned in RX, requiring the 'signed_char' option to maintain behavior. It also covers the 'auto_enum' option for automatic enum size selection and the 'dbl_size' option to specify double type size, which defaults to 4 bytes in RX compared to 8 bytes in H8 compilers. Configuration steps in the CS+ IDE are provided for each option.

- Application NoteAI-generated Summary: The document explains how to register and uninstall Call Walker within the High-performance Embedded Workshop (HEW). It guides users to launch HEW without opening a workspace, access the Tools Administration menu, and register the Call Walker tool by specifying the registration file path. After registration, Call Walker version 2.3 appears in the menu. Upon uninstalling HEW, users must manually delete the remaining Call Walker directory. It also provides Renesas Electronics website and contact information for support. The revision history notes the first edition release date.
- Application NoteAI-generated Summary: The SH-2 and SH-2A Fixed-point Library (Ver. 1.02) provides fixed-point arithmetic functions through the 'fixmath.h' header and corresponding libraries (sh2fix.lib, sh2afix.lib). It supports fixed-point operations like conversion between float and fixed-point types and trigonometric calculations. Usage instructions include copying files to local directories and specifying libraries in the High-Performance Embedded-Workshop environment. The library warns that results exceeding fixed-point range are not guaranteed. The 'fixmath.h' file defines types and macros for fixed-point operations, with function names indicating bit widths.Related Files:
- Application NoteAI-generated Summary: The document presents performance data of the signal processing library on SH2A-FPU and RX devices, detailing CPU cycles for various DSP functions such as FFT, FIR, and IIR filters across different sample sizes and coefficients. It also provides Renesas Electronics website and support contact information. The revision record notes the first edition release date as December 17, 2010.Related Files:View More (70)
