Build a Tiny OLED Display Subsystem 4 hours ago SSD1306 Out on a Cheap Date We live in an era where huge display screens are commonplace. But embedded systems often demand small displays, hopefully with low-overhead control electronics. In this project article, Jeff endeavors to design and build a low-cost 128×64 OLED display subsystem using an 8-bit MCU and I2C interfacing. Topics Discussed What are the choices in small displays How to craft a stripped down character scheme How to implement the display modes How to use UART interfacing and I2C Tech Used Microchip Technology PIC16F18313 MCU SSD1306 single-chip display driver from Solomon Systech
