mcb2300 elemental IO

[washburn]

Good afternoon,

I am using an MCB2300 Developement Board (ARM7) with a processor capable of 72MHz.  I am trying to create an audio sine wave out however the speed of the sine wave is limited by the 1ms tick.  I have placed a timed loop down and see options of 1kHz and 1MHz (which is greyed out and I cannot select) only.  Any suggestions?  Secondly the Elemental IO seems to be very limited (I see only one digital input, I see no timers)?  In all appearances the LabVIEW software seems to be very limited.

Sincerely,

Steve

hi washburn,

I believe the MCB2300 is currently limited to ms timing, as it does not reserve a timer specifically for this purpose.  If you want faster timing, you can use a timer interrupt and configure it in ticks.  This interrupt can then be used as an external timing source for a timed loop. The timer interrupts can be configured through the build specification dialogue (on the interrupt manager page).
