Importing Middleware/Drivers

RL78/G23 Group: Importing middleware (e.g. capacitive touch sensing middleware)

You can also use such middleware in conjunction with code from the driver code generator.

How to Use the RL78/G23 peripheral functions

Generating Driver Code

The Smart Configurator provides you with a GUI environment for generating driver code that handles the details of the settings of peripheral modules.。

Clock settings

Image
RL78 SC clock setting

You can make clock settings by selecting a clock source and making connections in the block diagram in the [Clocks configuration] window.

Component settings

Image
RL78 SC component setting

In the [Software component configuration] window, you can make settings for peripheral modules. After selecting the module you wish to set up for use, you can check for errors in settings (with some types indicated on the display) or switch the channels for use by drivers of multi-channel modules.

Pin Settings

The assignments of pins can be set up through a GUI, which also checks and offers solutions for cases of contention for the same pin by multiplexed functions.

The [Pins Configuration] window (displayed per peripheral module)

Image
RL78 SC pin setting

Specifying a peripheral module in the [Pins Configuration] window displays the pin functions for use by the module and allows you to set the assignment of the functions to pins.

[MCU Package] window

Image
RL78 SC mcu package window

The [MCU Package] window displays a symbolic view of the pins, indicating by colors which pins are and are not in use, which have been assigned contending multiplexed functions, and so on. This makes it easy to check the overall situation.

Automatic resolution of contention between pin functions

Image
RL78 SC pin conflict

In cases of contention for a pin, clicking on the pin brings up a list allowing automatic changing of the assignment of the pin to resolve the contention.
