How to Display CPU Temps and ADC Voltage?

Post by Belial88 »

Hi, so I'd like to use an RGB Negative 20x4 LCD (HD44780) http://www.adafruit.com/products/498 and arduino micro to display:
CPU Temp
GPU Temp
CPU Vcore
CPU VRIN

off a haswell i7-4770k/ud3h system. I'd use the adc from arduino micro, using actual hardwired voltage points, but I'm not sure how to get that to display on the LCD.

I also don't know how to get cpu temp or gpu temp on the lcd smartie, but I'd prefer to use HWinfo to do it.

Thanks
alx

Got almost the same setup as you, arduino nano with a 20x4 hd44780 negative display from ebay.

Found a sketch that emulates a matrix orbital display.

This works just fine, but you would not be able to change color or brightness on the display. (So why waste money on a expensive display? ;) )

If you decide to go my way you should know theres an issue with animated and custom chars with the code. Follow the fix under issues on the site.
