5/17/2012   Post a comment
HMIs developed with HTML5 reside in a high-level, virtualized environment but still need to access hardware. In mobile devices, for example, they need to retrieve the device orientation and, if there are GPS or accelerometer chips, information these chips provide for applications that use geo-location. In-vehicle systems need to retrieve even more information from low-level components such as the CAN bus, GPIO pins, and I2C and SPI devices. Persistent Publish/Subscribe (PPS) provides a simple, e
