ABSTRACT:
The present invention provides a bar indicator that minimizes the burden placed on the microcontroller. A horizontal bar indicator is generated that requires very little microcontroller firmware overhead, allowing a less powerful microcontroller to be used in the application. The reduced firmware requirement translates into smaller microcontroller firmware ROM requirements, thus enabling a lower cost system to be realized. The bar indicator uses a single byte written to a counter to represent the size of the bar. This byte written to the counter is readily available from the actual parameter value representing the size of the bar without significant additional calculation. The OSD video coming from the OSD logic is overridden with a pixel overwrite when the location of the bar indicator is located. The bar overwrites whatever is located at the position of the bar indicator. The pixel override occurs for a predetermined time. For example, if the bar indicator is set to the maximum range then the time may be twice as long as compared to the time to display a bar indicator that is set to at 50% of the range.
