The circuit in Figure 1 uses only five I/O lines to drive a dot- or bar-graph display of 20 LEDs. Although this version of the design uses a small and inexpensive one-time-programmable microprocessor, ...
Traditional bar-graph display adapter circuits have either employed large arrays of low-accuracy analog comparators or microprocessors with additional I/O porting to drive the multiplicity of ...
