ETAS Hardware Description
3.1.2 Configuring the Analog Signals
Which signals are assigned to the eight (ES5340.2-M) or six (ES5340.1-S) outputs
is defined in the output multiplexer (see
"Output Multiplexers for the Analog
Signals" on page 36 ).
You can configure the analog channels themselves as follows.
Analog Direct Out
This can be used to output constant voltages and values calculated in the com-
putation grid of an RTPC model – specified by the value of "OutValue_
n " [-1.0
to +1.0]:
U
out
= OutValue n * U

Resolver
If a resolver is used as the speed sensor, two analog channels (CH6 and CH7) can
be used for the output of the sine and cosine signal (see Fig. 3-2).
The following sensor chips have been tested:
• R/D Converter AD2S1210 (Analog Devices)
• Smartcoder
