NOTE: See the sample program JRIOTEST.C for an example of using the digital out-
put functions.
4.4.1.3 Analog Output
The two analog output channels on the Jackrabbit (DA0 and DA1 on header J5) are con-
trolled by a pulse-width modulation (PWM) driver. This requires the use of some fraction
of the CPU cycles when the driver is running (up to 20% when both D/A channels are
used). A voltage is selected by giving a value from 0 to 1024 to the driver, corresponding
roughly to 0.1 V to 3.5 V on DA0. Because of the PWM interrupt frequency, the PWM
driver can provide a continuous range of voltage output in the range from 0.1 V to 3.0 V
for DA0, and 0.6 V to 3.6 V for DA1. These ranges can be specified with the constants
PWM_MIN
, PWM_MAX0, and PWM_MAX1. In other words, setting channel DA0 to the value
PWM_MIN
will output 0.1 V, and setting it to PWM_MAX0 will output 3.0 V. Similarly, set-
ting DA1 to PWM_MIN will output 0.6 V, and setting it to PWM_MAX1 will output 3.6 V. Val-
ues below PWM_MIN will be rounded down to 0, and values above PWM_MAX0 (PWM_MAX1
for DA1) will be rounded up to 1024.
The output channels can also be set in an “always on” or “always off” mode, which does
not require CPU cycles. The “always on” mode is set by requesting an output value of
1024, and will provide about 3.4 V on channel DA0, and 3.6 V on DA1. The “always off”
mode is selected by asking for a value of 0, and provides an output of around 0.1 V on
DA0 and 0.0 V on DA1.
See Table 5 for a summary of the possible analog output voltages corresponding to values
given in the anaOut function.
