S12ZVC ADC 12bits Resolution with Processor Expert

jinliangsun — Fri, 13 Jul 2018 13:56:28 GMT

I'm working with DEVKIT-S12ZVC board. I use processor expert to configure the ADC module. With PE I can only select 8 bits or 10 bits mode but not 12 bits mode. But according to the reference manual it does support 12 bits mode.

1.4.13 Analog-to-Digital Converter Module (ADC)
• 12-bit resolution
• Up to 16 external channels and 8 internal channels
• Left or right aligned result data

...

Is it possible to use 12 bits mode with Processor Expert generated code?

Thanks,

Bruce

Hi,

9S12ZVC - 10bit ADC, 9S12ZVCA - 12bit ADC. Did you select non -A derivative?

Hi jinliangsun,

The Edward is right. When you creating the project you need to choose the variant of MCU S12ZVCA192 (in the case you are using DEVKIT-S12ZVC development platform for S12ZVC|NXP) as you can see below:

After that, you can select 12bit ADC.

I hope it helps you and thanks, Edward.

Best regards,

Diana

Hi Diana,

Thanks for your response. I did select the wrong derivarative.
