AS5043 10-BIT PROGRAMMABLE MAGNETIC ROTARY ENCODER

Adapter PCB Operation Manual

9 AS5043 Demoboard Software

The AS5043 Demoboard Software can be downloaded for free from the Internet at:

http://www.austriamicrosystems.com/03products/products_detail/AS5043/download_AS5043.htm?#software

It has several indicators and extra features, such as:

Displaying the absolute angle as 10bit-word (0..1023), as absolute degrees (0..360) and as rotary dial

Displaying the analog voltage output

Displaying the status and diagnostic bits (magnitude ranges) of the AS5043

Programming the zero position (OTP)

Programming clockwise or counterclockwise operation

Putting the AS5043 in alignment mode to aid centering the magnet over the IC.

Further information on the AS5043 Demoboard Software is available in the AS5043 Demoboard Operation Manual

9.1

Connecting the AS5043 adapter PCB to the demoboard

The AS5043 Adapter PCB is intended as a standalone device that allows easy and quick testing of the AS5043

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 8-pin female connector is designed to fit directly onto the AS5043 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.
