Overview
Description
An AP4 and Applilet is a standalone tool for automatically generating control programs (device driver programs) for peripheral modules in accordance with user settings. You can select the type of build tool (compiler). The control programs generated for the peripheral modules by the AP4 or Applilet are intended to suit the selected build tool.
Source code can also be generated for the IAR Embedded Workbench from IAR Systems and for MULTI® (support for RH850 and V850 family) from Green Hills Software and for the Development Studio (DS-5™; support for RZ family) from Arm® Limited.
Important: A Note to Users of the AP4 for RX: We recommend that you consider migrating to the Smart Configurator, as it supports the following three functions: importing middleware in the form of FIT modules, generating driver code, and setting pins from the AP4
The Code Generator plug-in is useful in conjunction with the GNU tools or Renesas compiler packages.
Features
- Standalone coding assistance tool
- Control programs generated for the peripheral modules suit the selected build tool (compiler).
- Simple operation by an easy-to-follow GUI
- Includes a feature to check for contention by peripheral modules for pins
- Supplies functions for operating peripheral modules in the form of an API

- Using I2C / IIC API code from AP4 / Applilet / Code Generator for RL78... only getting first clock
Overall I've been loving the AP4 Code Generator from Renesas for the RL78 (except for the billion possible names for the tool, not to mention I2C versus IIC, makes internet searches hard), but I'm having a problem getting I2C to work on my RL78 project and I've ...
