TMS470 HET PWM HalcoGen configuration incorrect

Other Parts Discussed in Thread: HALCOGEN

I'm trying to setup two PWM channels on a TMS470 in HalcoGen. When I configure the period for each channel to be 1000uS the output period ends up four times higher at 4000uS.

I've tried this same configuration on the RM48 and it works correctly, but all PWM configurations on the TMS470 HalcoGen seem to be off by a factor of four.

Hi Jotux,

Sorry, It's a known issue in 3.06.00 and is fixed in upcoming release.
The problem is with the Init function Duty and Period settings GUI.

Until the next HALCoGen release, please do below steps as workaround.

1) Close HALCoGen
2) Replace C:\ti\Hercules\HALCoGen\v03.06.00\drivers\TMS470MF066\HET470Mv000.xml with the attached xml file. 6622.HET470Mv000.xml.
3) Open HALCoGen, Open the HALCoGen project, Go to HET Tab, do the necessary settings, Generate the code.
