# Version 2 Software Prerelease ### https://github.com/tgolla/SphereBot Arduino Firmware for use with the Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit (https://www.adafruit.com/product/1438) and the optional addition of the Adafruit 2.8" TFT Touch Shield v2 with Capacitive Touch (https://www.adafruit.com/product/1947). This fork takes on a large number of changes including consistent naming conventions, an advanced G-Code parser, additional custom G-Code commands, a touchscreen control, SD card reader support and audio alerts. Many of these features are being actively developed. Additional documentation can be found in the documentation folder along with comments in both the SphereBot.ino and configuration.h files. This code release works with the original hardware configuration (Arduino & motor control shield) where g-code files are send to the SphereBot from a PC through a USB cable or you can add a touchscreen shield which allows you to operate in either the original mode cabled to a PC supplying the g-code file or in fully autonomous mode using g-code files stored on the SD card. Also addressed is a MAJOR bug fix in the arc drawing function. Previous code used the current x,y location stored in the stepper motor control code which was rounded to it's integer value while g-code values are represented with 6 decimal places (doubles). At times this would cause the start angle of the arc to be greater than ending angle, which resulted in the drawing of a full circle and not a partial arc. The version 1.9.4 prerelease is missing the follow features. - Version 2.0 release setup notes/documentation. - A completed comprehensive mechanical assembly document. - InkScape documentation stepping through creating gcode with the gcodetools along with using some of new the advanced Mxxx commands. https://www.youtube.com/watch?v=cl23-D_daTk
