A picture of the DAC output. The first 540 degrees represents a high and is at 3600 Hz, the next 360 degrees repesents a low and is at 2400 Hz. Note the cursors and the readout.

I am using the Audio DAC on the '802 to create a minimum shift keying modulation of 2400 Hz and 3600 Hz.

The auxiliary oscillator setup is found in the Oscillator part 3 of the dsPIC33F Family Ref. ...

Ttelmah, I get this error when I try to use the stopwatch with a MIPS of 22 Mhz.

Thanks for the replies.
PCM the stopwatch won't work above 20 Mhz.

My only question now is about clock cycles vs instruction cycles. The PIC33 has 2 clock cycles for each instruction cycle.
So ...

Congratulations and thank-you for your gracious help over many years.

TI / Burr-Brown make things easy with the DRV 101 series drivers.

You could use a op amp in the current to voltage mode to change the 20 - 200 ua to .4 - 4 volts; then feed the A/D.
Google "op amp current voltage"

It is probably a "typo" error. Look in your device .h file to see if the device is correctly identified. You should report this to CCS.

I don't think you can run your clock at 118 MHZ. There is a post divider that has a minimum divide of 2 so your clock would be 58,976,000

This is incorrect; the default post scale is di ...

It would appear that all the PCD folk did??? LOL

Look at the min high input for a 5v VCC. It looks marginal to me. TI and others have announced some new chips designed for level conversions and they may be a safer choice. Also look at the 74CX125 ...

Some LCD's need a pull-up resistor on the enable line. (Optrex).

Hello Cbarberis, I have been trying to use a DSP33 for a data collection project as I need the large RAM.
I am NOT a PIC or C expert and always struggle a bit; that being said:
I got a LCD working, ...

It looks like a typo; sfr:ADC... or sfr_ADC...
Try changing the .h file to the _ ?
I have found a few typos like this.
