How to setup ADC_ETC/PWM Sync mode in i.MX1170?

Hi Team!

I'm using MIMXRT1170-EVK and I want to setup ADC_ETC/PWM sync mode with Config Tools.

I was using MIMXRT1060-EVK, but with i.MX1170, the appearance of Config Tools has changed, and there unknow terms, and I don't know how to set it like before.

Q.1 Following is the i.MX1060 ADC and ADC_ETC settings. How can I set it i.MX1170?

Q.2 Following is the setting screen of ADC_ETC of i.MX1170.

What was called a channel group and conversion control group in i.MX1060 has been replaced by Command ID and Trigger.

I read the reference manual, but I don't know how to set in actual.
I would like to see the setting screen when the ATC_ETC setting of Q1 is applied to i.MX1170.

Hi @kerryzhou -san

I was able to solve by myself.
By enabling the setting of the red frame in the figure below, ADC_ETC worked.

Hi @kenji ,

  Please help to confirm two points:

1. When you use the CFG to configure the RT1060 ADC-ETC+ADC, it works on your side, right?

2. What's the CFG version you are using? Or from the MCUXPresso IDE? Which MCUXPresso IDE version. 

Please give me more information at first, then I can help you to check more details.

Best Regards,

Kerry

Hi @kerryzhou -san

I will answer the question.

  1. Yes, my PWM+ADC+ADC_ETC  code and settings on i.MX1060 works.
  2. This is the version of IDE I using.

The following is the current situation.

I want to do same thing on i.MX1170.
Could you tell me how to set on Config Tools?
I would like to see the screen after end the settings on the i.MX1170.

Hi @kenji ,

 Please also share me your working RT1060 configure file or the project, then I will help you to check more details in the RT1170.

  Please keep patient, I need more time to do deeper checking, thanks.

Best Regards,

Kerry

Hi @kerryzhou -san

I uploaded RT1062(MIMXRT1060-EVK) and RT1176(MIMXRT1170-EVK) board folder and .mex file.

Please check it.

  • What I want to do is to do ADC every PWM cycle for PMSM motor.
  • RT1062 works fine.
  • RT1176 doesn't work as expected.  First, ADC_ETC error interrupt occurs. ADC_ETC_IRQ0 is done every two cycles. ADC is working correctly at ADC ETC IRQ0 interrupt. Also, interrupt timing of ADC_ETC_IRQ0 should be the timing of ADC_ETC_ERR in below figure.

By the way, is there any way to know why ADC_ETC_ERR interrupt happens? 
I couldn't find out register that have ADC_ETC_ERR interrupt error flags.
I think, if I can know the reason for the error, it will help me to solve the problem.

Hi @kerryzhou -san


The following is the manual and setting screen of i.MX1170 regarding ADC_ETC.

  1. How set the conversion trigger of chain configuration?
  2. Is the trigger source and conversion trigger the same or different?
  3. Is segment and command ID the same or different?
