MAGALPHA COMMUNICATION KIT SETUP
Follow the step below to setup MagAlpha Communication Kit.
1. Install Macom Application Software (Windows only)
2. Configure LPC-Link2 board in flash boot mode.
3. Plug connector board to the LPC-Link2 (EVMA-CONN or TBMA-CONN).
4. Connect daughter board to the sensor board (EVKT-KNOB or TBMA).
5. Connect LPC-Link2 to computer.
6. Start Macom App.
Install Macom Application Software
Visit the Monolithic Power Systems website at www.monolithicpower.com and go to the Position
Sensors Design Support page. The Macom App can be found on the Software section.
Configure LPC-Link2 Board In Flash Boot Mode
Plug the jumper on JP1 to configure the microcontroller in flash boot mode. In this mode, the
microcontroller will load the firmware binary stored in the flash.
Figure 12: Configure LPC-Link2 to flash boot mode
Plug Connector Board To The LPC-Link2
Plug carefully the desired connector board to the LPC-Link2 as shown on the figure below. Check that
female headers are correctly aligned with the LPC-Link2 pins before connecting the two boards
together.

Figure 14: Assembled LPC-Link2 with TBMA-CONN daughter board
Connect Daughter Board To The Sensor Board (EVKT-KNOB or TBMA)
Use the provided ribbon cable to connect the connector board to the sensor board.
EVKT-KNOB is delivered with pre-soldered female socket connector while TBMA boards are delivered
without it. TBMA boards require therefore to hand solder the female connectors in order to be used with
the EVKT-MACOM. Before soldering, make sure to place correctly the connector polarization slot next
to pin 1 (as shown below).
Figure 15: Solder connectors CN1 and CN2 to TBMA
On TBMA boards (RD and LT), CN1 connector must be connected to the TBMA-CONN CN1 connector
using one of the provided 8 conductors ribbon cable. CN2 connection is not required for SPI
communication but provides an easy access to MagAlpha output signals on the LPC-Link2 daughter
board.

MACOM APP
The Macom software is a powerful and easy to use application to interact with the MagAlpha sensor
family. It provides a graphical visualization of the angle output and a convenient way to read and write
sensor parameters. In addition this App also offers the following features:
Register map overview (Read/Write sensor registers)
Import configuration script (JSON)
Export current configuration (JSON)
Save measurement data
Update EVKT-MACOM firmware (stored on LPC-Link2 Flash)
Sensor Auto Discovery (automatic detection of the available parameters and of the sensor
generation)
The Macom graphical user interface is divided in 3 areas:
The toolbar
The angle readback
The sensor parameters

Feature Name
Description
Connection
Switch On/Off the USB connection to the EVKT-MACOM. It also launches a sensor
auto discovery when connection is switched On (see
Sensor Parameters).
Save Data
Save the latest 2000 measured angle in a csv file (can be also open natively by any
Spreadsheet applications like Excel).
Registers
Switch On/Off the registers overview window display (see Figure 24). This window provide
the overview of the complete register map in a glance. Users can switch between decimal,
hexadecimal and binary register value representation by using the dropdown button. It is
also possible to refresh all registers value by pressing the Read button.
Import
Import sensor register settings and/or Macom configurations from a JSON file.
Export
Export sensor register settings and Macom configurations to a JSON file.

Raw input
Measured angle value coded on 16-bits (0 to 65535) and in degree (0 to 360)
Resolution
Gives 6σ resolution in bit (n) and 3σ resolution in degree (m). Which means that 99.7% of the
measurement performed on this sensor will have the same nMSB bits and will be within ± m
degrees from the latest angle measurement.

Sensor Parameters
The user-configurable parameters are defined during the “Auto Discovery” process. During this
discovery process (at Macom App startup or when users do a disconnection/connection cycle) the
software will automatically discover which sensor generation is connected and then find out which
parameters are available for this specific product.
Figure 26: Macom App Sensor Parameters
A connection cycle is required after a sensor “Hot Swap” (connecting or unplugging the sensor while
the system is ON), in order to rerun the auto discovery process on the freshly connected sensor.
To perform a connection cycle simply click on connection twice; the first time to disconnect the device
and the second time to reconnect it.
