AS5011

Low power Integrated Hall IC for human interface applications

DEMOBOARD AND SOFTWARE OPERATION MANUAL
1 General Description

The AS5011 is a complete Hall Sensor IC for smart navigation key applications to meet the low power requirements and host SW integration challenges for products such as cell phones and smart handheld devices. Due to the on chip processing engine, system designers are not tasked with integrating complex SW algorithms on their host processor thus leading to rapid development cycles. The AS5011 single-chip IC includes 4 integrated Hall sensing elements for detecting up to ±2mm lateral displacement, high resolution ADC, XY coordinate and motion detection engine combined with a smart power management controller. The X and Y positions coordinates and magnetic field information for each Hall sensor element is transmitted over a 2-wire compatible interface to the host processor. The AS5011 is available in a small 16-pin 5x5mm QFN package and specified over an operating temperature of -20 to +80°C.
2 The AS5011 Demoboard

The AS5011 demoboard consists of an input module and an USB interface PCB. The whole system is USB powered. Once plugged on a PC running Windows, the AS5011 demoboard will work as a standard HID mouse. Pressing down the knob of the module works as a left mouse click.

Figure 2 AS5011 demoboard

As the AS5011 is considered as a standard HID mouse in Windows, a right mouse button has been implemented.

In order to compensate an inaccurate centering of the module’s knob, an automatic centering calibration is performed each time the demoboard is plugged on the PC. The calibration procedure can be manually done by clicking the calibration knob on the USB interface. If this button is kept pressed, the mouse pointer doesn’t move, but can be controlled by the normal mouse or touchpad of the PC. The AS5011 Mouse and a standard mouse can work in parallel if they are connected at the same time.

Two LEDs are present on the USB interface
• Power Mode LED Indicates the actual power mode configured in the AS5011, and automatically updated. - Power mode LED off Shutdown mode 50uA current - Power mode LED on Low power mode 200uA current
• Center LED Indicates that the knob is centered on the 0,0 corrected position
3 AS5011 Mouse pointer

Due to the high number of velocity steps provided by the AS5011 to the Windows mouse driver, the pointer displacement speed can be too high to control it properly.

The mouse pointer speed can be configured in Windows Settings Control Panel Mouse

Depending on the PC and the user’s feeling, speed level 1~level 3 are the best values.

Getting Started

As the AS5011 Demoboard works like a standard HID mouse, no software is needed to test it. But for more flexibility and in order to become familiar with the principle of the AS5011 sensor, the AS5011 Mouse GUI software allows to modify the device registers, read the magnet coordinates and change some attribute of the mouse. In order to get started, you need:
• The AS5011 Mouse GUI Software installer
• a or Windows operating system
• one free USB slot on your PC to connect the demoboard

Installing the Software

Before plugging the demoboard on the PC, execute the AS5011 Mouse installer, and follow the instructions.
