CAN Controller Usage: Applications and Frequently Asked Questions Rev.2.03
Log in to Download PDF 1.81 MB R01AN2535ED0203-CAN Rev.2.03 May 15, 2019
AI-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.

RX Development Environment Migration Guide Migration from SuperH Family to RX Family (IDE ed.) (High-performance Embedded Workshop to CS+)
PDF 1007 KB REJ06J0102-0200 Rev.2.00 日本語 Apr 20, 2017
AI-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.

Compiler Package Application Note: The application guide of Call Walker Rev.1.00
PDF 243 KB R20AN0294EJ0100 Rev.1.00 日本語 Feb 18, 2014
AI-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.

SH-2A Open Source FAT File System M3S-TFAT-Tiny: Introduction Guide
PDF 252 KB R20AN0190EJ0101 Rev.1.01 日本語 Nov 08, 2013
AI-generated Summary: The TFAT library supports FAT12, FAT16, and FAT32 file systems with 8.3 filename format and one drive. It is based on Fatfs (RO.06) and does not support long file names or filesystem formatting. The software stack includes the FAT file system, TFAT library, and device drivers. Development uses High-performance Embedded Workshop and SuperH C/C++ compiler. Compiler options for SH-2A and SH2A-FPU are specified. Version 2.00 is available for both CPU types. The library requires about 8.4KB ROM, 6 bytes RAM, and varying stack sizes depending on API functions. Memory allocation depends on the number of open files and directory structures.

SH-2, SH-2A Fixed-point Library (Ver. 1.02)
PDF 242 KB R01AN1355EJ0102 Rev.1.02 日本語 Sep 11, 2012
AI-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.
