In this post on the Arduino.cc forums and this blog post, [Majek] announced that he had fooled the AVR microcontroller inside and Arduino into writing user data into its own flash memory during run… ...

Renesas Electronics has introduced the new 16-bit RL78/L23 microcontroller (MCU) group, expanding its low-power RL78 family.

How do you save data from an Arduino-based device to a memory card? Fortunately, a microSD card and SD card breakout board now make this an easy task.

Renesas’ RL78/L23 16-bit MCUs provide LCD control and capacitive touch for responsive HMIs in smart appliances, electronics, and meters.
