    Hi Bluehash, No, not yet, but we have a complete working diagram to program the motor kit here: http://www.vissim.us/solutions/field_oriented_motor_control.html It explains how the diagram was developed and lets you download both the source diagram and the debug diagram. You can control motor operating...

    Hi Charlie, I just purchased the Motor Control and PFC Developer kit, and am having trouble with the XDS100 software driver installation. On my PC, I already have the full version of CCS 3.3. The problem I'm having is that in order to get the F28035 emulator driver in CCS Setup, I had to install...

    Hi Mike, >> In the first posting you mentioned having installed 2 different version of CCS ; this should mean that you have 2 different CCSetup programs. I am wondering if the correct CCSetup was chosen when you were looking for the F28035. Sorry if I wasn't being in my first post. I did...

    sunil barot
    I am looking at available external ref. for ADC for F28035 Piccolo. Recommended max. voltage for external ref. (VDDA) is 3.63 V. Can I use 4.096 V ref. since the absolute max on any pin is allowed upto 4.6 V ? How are recommended values derived ?

    Hi Arefeen, As I posted above, we have use our block diagram language VisSim to program the F28035 for sensorless FOC. With the control loop clocking at 10 kHz, only 27% of the 100 microsecond sampling interval is used without using the CLA. So you could go 30kHz if you wanted to. Note that we have...

    Jerome, The F2803x ADC does not have a fixed value for VREFHI in external reference mode as ADCREFIN does on the F280x. VREFHI can be any value between 2.64v and the VDDA rail, or 1.98v and VDDA if VREFLO = 0v. Refer to the data manual on p.120: http://www.ti.com/lit/gpn/tms320f28035 The F2803xp...

    Thank you Ritchie, The problem got modified a bit from what it was. The CLA computes the frequency information in the form of clock counts (period). It transfers the counts to CPU as a float variable. For example it computed the period to be 333.4105 counts that is represented by hex as 0x43A6B48C...
