TCPmaker Embedded web server software for PIC devices provides a wide variety of gauges and indicators, to display numeric values.

[video demo of gauges and indicators]

Linear gauges are very versatile.  They are a natural choice for displaying things like how full a tank is. The versions without bezels are narrow enough that an number of them can be placed next to each other, as you would do in an audio spectrum bar graph.

Radial gauges have a moving needle. They are a natural choice for displaying quantities like speed, or instantaneous audio volume.

Sometimes you need to see a precise numerical value for the quantity you are displaying.  TCPmaker Pro provides several indicators that display a quantity as a formatted string (You control the format with a TCPmaker [link to Format Your Data With No Code] string variable.

TCPmaker Pro's gauges and indicators come in a number of variations:

• With a surrounding bezel, so you can display the same quantity in both graphical and numeric form.
• Without a bezel, to save space so you can place indicators close together on a page
• With adjustable color bands, to optionally indicate warning and danger zones at the low and high end of scale.
• Without color bands, for simplicity
