Hi NXP

Does MKL17Z32VLH4 can do multiple 19ch ADC with DMA transfer?

below is my requirements:

19ch ADC, needs DMA transfer,  finish ADC sampling and DMA transfer in 100us~200us

I found a link is use MKL25 and measuring all ADC with DMA, but demo code has been removed.

Measuring all ADC inputs on FRDM-KL25 using DMA 

could you help to check my requirements can achieved by MKL17Z32VLH4 ? 

Thanks,

Hello Leo Wu

 

The microcontroller can cover the specifications you described, but not all the adc channels might be available. You can check chapter 10 "Pinouts and Packaging" of the reference manual.

 

Regarding Measuring all ADC inputs on FRDM-KL25 using DMA the example can be found here: KL25_MultiADC_DMA.zip 

 

You can use this example for reference, this project was designed for processor expert in codewarrior. If you prefer, you may use MCUXpresso, this IDE has a similar tool named ConfigTools. This will allow you to configure the peripherals as Petr mentions in this post: https://community.nxp.com/docs/DOC-96507 

 

Let me know if this is helpful, if you have more questions do not hesitate to ask me.

Best Regards,

Omar
