R32C/111 goes OLED

OLEDs are hot news these days and rightly so, considering the new opportunities and applications they offer. It’s not all plain sailing, however, since driving them by microcontroller presents developers with a number of challenges.
Continuing our series on the Renesas R32C, we trawl the theory to come up with a highly practical solution using the R32C carrier board.
Organic LEDs — OLEDs for short — represent the latest in display technology and in the truest sense of the word offer ‘visible’ advantages over the now widespread TFT liquid crystal display (LCD).
