- change language of an existing Smart Configurator project from C to C++
Hi all, a year ago we started a software project in C, using RA Smart Configurator. Now we want to move to C++. How can we change an existing Smart Configurator Project from C to C++. I only see the language setting, when setup a new Configurator Project. Thanks in ...
Jun 9, 2022 - Could not able to configure QSPI for micron chip(MT25QL512ABB8ESF-0SIT) in smart configurator
... flash for micron chip (MT25QL512ABB8ESF-0SIT) for RX66N (R5F566NDxFC) and in smart configurator have an option to configure only for Macronix devices. I could see the code for Micron N25Q but not finding how to configure in smart configurator. Please guide us how to configure for micron devices. Thank you!

May 14, 2024 - RL78 Family: Why can't the maximum transfer rate be used in master mode with Simplified SPI (CSI) in Smart Configurator?
Please refer to the "Electrical Characteristics" section in the user’s manual. The transfer rate for Simplified SPI (CSI) communication depends on the operating voltage range. For example, in the RL78/G23, when HS mode is selected and EVDD is set between 1.8V and 5.5V, the transfer ...
