Description
Many modern control circuits use the value from a digital counter to directly determine a setting or position. Manipulating this value under computer control is not difficult, but when one has to interface with a human operator, several other factors must be considered. Human interfaces often require that the circuit respond to changes in a setting – up or down, left or right, clockwise or counterclockwise. These controls need a simple interface, which the ELM415 provides.
