TMS320F28379D: eCAP input select as ECAP_selectECAPInput() is not avaiable for this device

Naveed Ishraq

Part Number: TMS320F28379D
Other Parts Discussed in Thread: LAUNCHXL-F280039C,

Hello,

Previously when I used a LAUNCHXL-F280039C, it had a function called ECAP_selectECAPInput() available in ecap.h file. I used to take a ADC 0 signal as an input to this eCAP1 using the following code,

XBAR_setInputPin(INPUTXBAR_BASE, XBAR_INPUT7, ADC_CH_ADCIN0);
ECAP_selectECAPInput(ECAP1_BASE, ECAP_INPUT_INPUTXBAR7);

But now I am using the TMS320F28379D which don't have the ECAP_selectECAPInput() available. How can we give the ADC signal to eCAP input without any external connection?

Can you please help?

Thanks!

Hi Naveed,

There is no mux for eCAP input on this device. It is fixed to Input7.

Thanks & Regards,

Santosh

Thanks for the reply Santosh. I just want to confirm that if we want to route a signal from a GPIO to eCAP1 then the following line should be enough for eCAP to know which signal it needs to track,

XBAR_setInputPin(INPUTXBAR_BASE, XBAR_INPUT7, GPIO_x);

Regards,

Naveed

That is correct, Naveed.
