Adapting HVACI Sensorless example to Concerto F28M35x

Other Parts Discussed in Thread: CONTROLSUITE

Hi,

I am trying to use the example project HVACI_Sensorless with the Concerto and the High-voltage Motor Control + PFC kit v2.0 (TMDSHVMTRPFCKIT). I am using the docking station before to use the TMDSHVMTRPFCKIT.

The C2000 the Concerto has it's equivalent to the piccolo, isn't it? So first I build a project for the M3 to enable and assign all ports to the C28x.

After loaded and ran the program on the M3 I load and run the HVACI_Sensorless.out on the C28x but it hangs on the line 482 of the HVACI_Sensorless-DevInit_F2803x.c waiting for the PLL to be locked:

while(SysCtrlRegs.PLLSTS.bit.PLLLOCKS != 1) { }

Why the PLL doesn't lock?

Thanks,

Cerilet,

I'll suggest you to look at the SolarExplorer Kit example in controlsuite that uses Concerto,

On Concerto the PLL master is the M3, and hence the C28x cannot write to these registers, You are using dev init of F2803x file, so it will not work.

The software can be found at

ti\controlSUITE\development_kits\SolarExplorer_v1.0\SolarExplorer_PVInverter_F28M35Hx

It has two projects one for the C28x and the other for the M3,

I'll take a look on that.

Many thanks,
