• Gnatstats Tiny OLED PC performance monitor  &  HardwareSerialMonitor  Windows Client  

by Rupert Hirst and Colin Conway

This project, assumes you have above average experience with Arduino, the IDE, compatible boards available and other related hardware.

___________________________

Project principles:

The HardwareSerialMonitor application  detects the sensors of most modern PC graphics, CPU and motherboards whilst, also pooling windows hardware stats.

This data is then sent over a serial com port to an Arduino Microcontroller running the Gnat-Stats Sketch and displayed on the OLED/TFT display.

Compatible boards:

•    ProMicro   (Atmel ATMega 32u4) 
•    Adafruit QT-PY / Seed Studio XIAO Series

Compatible Screens:

• OLED :  SSD1306 (i2c) or SH1106 (i2c)  128x64 Pixels 

Note: SH1106 are usually  screens over 0.96" but not limited to. The (GND/ VCC) pin out order is different, although, more recent versions have the same pin order as the SSD1306 (VCC/GND), buyer beware!!!

Library and MCU core links are included within the Arduino sketch.

Notes:

•               Plug the Arduino into a dedicated USB Port, try avoid using a USB hub. Timings can be critical to avoid garbled or corrupted screen info

•               HardwareSerialMonitor was designed for dedicated GPU's . Your mileage will vary with Integrated Graphics
