selected to either 1, 4, 8, 12, 16 or 24 bits by calling function
DIOsetChanWidth
(see section
6.6.10.3 for more details). The PPI Port(s) used by the digital input channel must be
programmed as input by calling function DIOsetMode for each port (see section 6.6.10.2
"Configure a Digital I/O Port for Input or Output - DIOsetMode").
The enableInterrupts and disableInterrupts functions must then be called to enable and disable
the 'update' interrupts, and, when finished, function TCfreeDCO frees up the resources used so
they can be used again by another program.
4.2.10 Voltage Controlled Oscillator
In combination with one of Amplicon's data acquisition boards, providing an analog (voltage)
input channel, a Voltage Controlled Oscillator can be implemented. The operation would be
identical to the DCO described above, except that, rather than reading a digital input channel,
an analog input channel voltage can be measured to provide the frequency control.
Function
TCsetVCO
(section 6.6.9.2) implements such an arrangement using the PC215E
combined with one of the following data acquisition boards also available from Amplicon:
• PC226E (order code 909 561 63)
• PC30AT (order code 908 931 53)
• PC26AT (order code 908 931 73)
• PC27E (order code 909 561 13)
The data acquisition board must be configured with the following jumper selections to give a
+10V unipolar analog input range:
1. PC226E not applicable - analog input range is software-programmable.
2. PC30AT J8 = UNI
J7 = 1
J3 = C
J10 = /D11
3. PC26AT J7 = UNI
J1 = 1
J2 - C
J8 = /D11
4. PC27E J1 = UP (+4V unipolar)
Care must also be taken to ensure that the base address and interrupt levels of the PC215E
and data acquisition card do not clash.
