Lab 4 question using Launchpad and BoostXL

Tom Hoag

I have worked thru most the labs with good success.

Regarding the watch variable: gMotorVars.IqRef_A This is set =0 when Run is clicked in the CCS debugger. What file can I change gMotorVars.IqRef_A so its value at Run time is = 2? What statement would I use for this?

Thank you!

Tom,
if you look at the use of that variable in proj_labo4.c you will see it at
_iq iq_ref = _IQmpy(gMotorVars.IqRef_A,_IQ(1.0/USER_IQ_FULL_SCALE_CURRENT_A));

inside the updateIqRef() function

you can hard code this either directly in this line, or by setting gMotorVars.IqRef_A = _IQ(2.0)
