App note: How to Port U8g2 to LPC55(S)6x and support a mono OLED display

App note from NXP Semiconductors helping you to use cheap OLED panels found on Taobao or Amazon to interface with their LPC5500 series micro using U8g2 graphics library. Link here (PDF) The LPC5500 is an Arm® Cortex®-M33 based microcontroller for embedded applications. There are many 128 × 64 resolution OLED panel modules on the market […]

Current meter based on ESP-12E and LTC4150

Victor Chew made a simple current meter based on ESP-12E, LTC-4150 and SSD1306 OLED module that measure the average current draw of a variable load accurately: The meter is powered by the micro-USB port on the ESP-12E. I soldered header pins onto the IN and OUT terminals of the LTC-4150. The whole idea is that […]

Tutorial: Adding the SSD1306 OLED screen to an Arduino logger (without a library)

Edward Mallon writes: While I loved the Nokia 5110 LCD’s readability in full sun, the pressure sensitivity was a real problem for the underwater units. So I started noodling around with some cheap OLED screens from eBay. With the exception of the init & XY functions (which are more complicated on the 1306 controller) the […]

SSD1306 and Python with the BeagleBone Black

Ethan Zonca of Protofusion writes: The SSD1306 is an OLED display made with SPI and I2C interfaces. With a simple Python library I adapted (a modified version of py-gaugette), it is easy to render text, images (from bitmaps of pretty much any format), progress bars, etc. This guide is a bit on the long side, […]
