Hello,

My evaluation board: NXP IMXRT1050-EVKB.

SDK_2.6.0_EVKB-IMXRT1050

There is only sdk example:  adc_etc_hardware_trigger_conv

I try to understand, how can I config ADC with DMA ?

I can't find any documents that explain this type of configuration.

Also no examples refer to this issue.

Best Regards,

Leon.

Hi jeremyzhou Employee,

I see the next example : https://community.nxp.com/docs/DOC-335320

Very similar to my request.

One of my questions,

1. SIM->SOPT7 |= 0x8EU; 

This type of register doesn't exist in IMXRT1050.

How I link between ADC and QTMR ?

Best Regards,

Leon.

Hi jeremyzhou Employee

Thank you for this info,

But  I expect to see the real example as part of IMXRT1050 SDK.

Is it expected to add such an example and when?

Best Regards,

 

Leon.

Hi Leonid Shigris,

Thanks for your reply.
1) Is it expected to add such an example and when?
-- As I know, there's no plan to add such example in the SDK in recent.

Have a great day,
TIC

Hi Leonid Shigris,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
Yes, there's no similar demo as you want in the SDK library, but I've attached two application notes which describe how to combine the ADC and DMA, even these two notes are base on Kinetis MCU, however, they still can inspire you, as RT MCU and Kinetis share the ADC and DMA IPs.

Have a great day,
TIC
