grbl_hmi | Simple LCD and PlayStation2 controller interface

grbl_hmi is a Java library typically used in Internet of Things (IoT), Arduino applications. grbl_hmi has no bugs, it has no vulnerabilities and it has low support. However grbl_hmi build file is not available. You can download it from GitHub.

this is a very simple arduino hmi for grbl. it links to my fork of grbl and provides an lcd displaying position and a ps2 controller to give some control over manual operations. to use: place these files in a directory called grbl_hmi and open the grbl_hmi.pde in the arduino ide. the code uses the lcd and ps2x_interface modules. grbl_hmi gets counts from the main grbl code. it needs lc_display.h to give it the sacling between counts and millimetres. the format should be fairly obvious from the code, but see also the i2c.cpp code in the grbl project, which gives the other half of the relationship. the two wire interface, or i2c bus, is used to communicate with grbl. five byte packages are sent to the hmi: the
