Overview
Description
The RX130 Group integrates a built-in max. 36-channel capacitive touch sensor. The capacitive touch sensor uses an improved detection method compared to previous products and so has vastly improved noise immunity, sensitivity and water resistance. As a result, malfunctions have been reduced, and touch keys are now able to be applied to a variety of materials like e.g. wood, other than the typical acrylic or glass: The RX130 touch feature is an ideal fit for consumer electronics products that are used in wet environments such as in the kitchen or bath. The RX130 Group has a lot of built-in functional safety hardware, and can easily support the IEC/UL 60730 safety standard for consumer electronics. The RX130 operates at a maximum voltage of up to 5.5V. So it is suitable for applications such as home appliances (washing machine, IH cooking heater) with touch panel function.

Strange I2C behaviour on RX130
Hi there, I'm using the RX130 target board for interfacing to some I2C peripherals. For a basic test, I've created a blank project, configured with the default RIIC communication driver using the Smart Configurator, and in the main() function call: R_Config_RIIC0_Create(); R_Config_RIIC0_Start ...
