TMS320F2800137: CMPSSLITE bug in Sysconfig

Part Number: TMS320F2800137
Other Parts Discussed in Thread: SYSCONFIG

Hi,
I'm using SysConfig 1.16.2 to configure CMPSSLITE High Comparator with positive input connected to an analog signal and the negative input connected to internal DAC. My assumption is that i will need one analog signal configured for CMPHPMXSEL, and no analog signal needed for CMPHNMXSEL, but sysconfig needed two pins.

any help with that?

thanks

Hello Mohamed,

Thank you for your patience.

You need to change the "Analog PinMux" settings to provide access to the pins being used in CMPSS module. You can either change "Use Case" to "ALL" or add the needed pins to the list in "Pins Used".

Regards,

Hadi

Hi,

thanks for the reply.
My isse is why CMPSS_LITE is asking for two pins for each comparator (H or L) even if the neegative pin will be connected to internal DAC?

Mohamed,

If you resolve the issue with the Analog PinMux, then it will ask only to select positive pin as the negative pins is coming from internal DAC.

Hadi
