After performing automatic adjustment procedures
analog and ABZ output signals can be checked with
an oscilloscope. Figure shows the positive sine (yel-
low) and cosine (blue) signal at output pins PSIN
and PCOS of the motherboard (iC-PZ EVAL PZ1D).
Please note that the single-ended output signals
should have an offset of 2.5 V and an amplitude of
about 250 mV in default analog output selection.

FURTHER CONFIGURATION HINTS
Filter configuration for system development
•
The default filter values
IPO_FILT1 = 110 [ = 0x6E]
IPO_FILT2 = 4 [ = 0x04]
ensure stable filter operation before analog signal ad-
justment compensates signal errors. However, with
the default settings, neither high-precision nor high-
dynamic-systems show best performance. It is thus
recommended to change the filter settings after signal
adjustment. As a starting point for system develop-
ment, the following settings are recommended:
IPO_FILT1 = 25 [ = 0x19]
IPO_FILT2 = 4 [ = 0x04]
Port configuration and output signals
•
The jumper setup of the scanner module (iC-PZ2656
EVAL PZ1M) recommended in this application note
enables analog (PORTC), ABZ (PORTB) and BiSS
(PORTA) outputs. Other possible output signals are
SSI, UVW and SPI. For more information regarding
the port configuration check the eval board descrip-
tion and the datasheet at
BiSS Reader Software
•
To evaluate the BiSS sensor communication, iC-Haus
offers a BiSS Reader Software.
Note that
the BiSS Reader requires LabVIEW
™
Run-Time
Engine (RTE). The current version and its re-
lated software manual are available with RTE at
and without RTE at
