Sensor Mode 2 Circular Progress

A circular progress sensor (known as fan in the AOOSTAR-X software) masks a progress bar image for a certain angular range based on the corresponding sensor value. The masked image is alpha-blended with the panel image.

Sensor configuration fields:

• mode: 2 (for fan)
• direction: 1 = clockwise, 2 = counter-clockwise
• label: label identifier, also used as sensor value data source identifier
• x, y: position on the panel
• width, height: size of the circular progress element (not yet used)
• pic: circular progress image to overlay. Should match width, height
• minAngle, maxAngle: range of the masked image
• minValue, maxValue: clamp sensor value to this range
• xz_x, xz_y

Example

The following configuration and graphics are taken from the 仪表盘_windows panel configuration in 有线网卡 windows驱动.rar.

Example panel.json with a single "fan" indicator sensor and the following (partial) background image in img:

Known Issues

Fan sensor rendering has been reverse engineered from the AOOSTAR-X app. Not all options are supported.

• Work in progress, not yet fully tested
• direction: 2 doesn't seem to work
• widht, height should be considered and auto-resized as for mode 4
