nathan bryant / Mbed 2 deprecated Grove_LCD_RGB_Backlight_VFD_Display

A platform to create a remote control with display for a 10hp up-cut saw that cuts aluminum, plastic and other materials. It is controlled by a Variable Frequency Drive (VFD) which is mounted at the back of the saw, making it inconvenient to change the blade speed to match the material being cut.
