PE lacks many ADC channels

[wujiankang]

I use the MCU MPC5748G and the MCU has many ADC channels, but I fund the PE lacked many channels in the S32DS.

For example:

The channel corresponding to the port PD[11] is channel 15 and the source of inputs ADC_1 corresponding to the port PD[11] is ADC1_P[15].

But the PE has no ADC1_P[15] in S32DS.

Excuse me, how to solve this problem?

Hi,

Ye, if you select the package which don't have this pin routed out, you simply cannot use it.

That is limitation which is reflected on price.

Yeah, I see and thanks.

Hi,

Please make sure the selected CPU variant in PE matches the one you are using. For example, the default is the LQFP176 variant, also used in all the examples. This variant does not have pin PD[11], which is the only one assignable as ADC1_P[15].

The PE correctly reflects this information:

After I select the 324-pin CPU variant, I can see ADC1_P[15] in the list:

Hope this has been helpful.

Best regards,

Ovidiu
