9 AS5045 Demoboard Software

The AS5045 Demoboard Software can be downloaded for free from the Internet at:

http://www.austriamicrosystems.com/03products/products_detail/AS5045/download_AS5045.htm?#software

It has several indicators and extra features, such as:

Displaying the absolute angle as 12bit-word (0..4095), as absolute angle and as rotary dial

Displaying the pulse-width-modulated (PWM) output as bar-graph

Displaying the Push-Button functionality (MagCompEn)

Putting the AS5045 in Alignment mode

Permanently programming (OTP) the zero position or CCW bit.

Reversing the direction of rotation

Further information on the AS5045 Demoboard Software is available in the AS5045 Demoboard Operation Manual

9.1

Connecting the AS5045 adapter PCB to the demoboard

The AS5045 Adapter PCB is intended as a standalone device that allows easy and quick testing of the AS5045

without the need of having to make your own PCB.

It allows access to each IC pin via a standard 100mil pitch, 600mil Dual-In-Line connector, has LEDs on all digital

outputs and comes with an onboard 5V linear voltage regulator (78L05) and a battery clip to supply the board from

a 9V battery.

The 7-pin female connector is designed to fit directly onto the AS5045 Demoboard and use the Adapter PCB as

external encoder (software setting: Encoder = external).

The demoboard however, runs at 3.3V supply voltage. The Adapter PCB is configured for 5V supply voltage.

Connecting both boards without modifications will not harm any of the boards, but may lead to data transmission

errors due to the different digital levels, especially when an extension cable is used between demoboard and

Adapter PCB.
