I want to connect pcf8563 rtc integrated circuit with rx140. Is there a chance to find ready code including smart configuration via e2studio?
This IC appears to communication via I2C which is supported by the Smart Cfg. Finding code that interfaces to a device from NXP would likely require finding sample code provided by NXP that could be adapted to a non-NXP device.
Thanks for your interest. There is no 'Vbat' pin on Rx140. Is there a way to advance the internal RTC when there is a power outage?
