Sensirion SFM3x00 series flow meter. Supported devices include SFM3200, SFM3300 and SFM3400. Wraps a modified version of https://github.com/PubInv/SFM3X00. This is a work in progress. I do not have the device so have not been able to perform any testing.
Nodes to work with WS2812 (NeoPixel). The main difference from the other libraries that this library does not use a buffer to light up the LEDs. So it gives a possibility to light up a really long LED strip with a small microcontroller without a huge amount of RAM.
Nodes to drive ST7735 based TFT LCD displays. This library supports 128x160 resolution displays which are connected through the hardware SPI interface. Physically, some displays based on the 7735 chip may differ from each other and have different sets of instructions for initialization. To solve this, the library contains several device nodes for different types of displays. These nodes are labeled "B", "G", "RG", and "RR".
