I was hoping to use the medium quality sound (MQS) output for my project but am a bit stuck. There doesn't appear to be a demo for it and the information available in the processor reference manual seems vague to me (or I'm just not grasping it well enough). Basically, I have 16-bit data that I need output as an analog signal for audio (left and right audio data will be identical). Can you give me some guidance about how to set the MQS up and get it going?
I've also imported the PWM demo and am considering trying to just use PWM directly but haven't gotten very far yet. Having to just scrape time together to work on this.
Anyway, any and all help is appreciated! And sorry if the question seems too broad or vague.
I also have difficulties to setup MQS module on MIMXRT1050-EVK eval board (SCH-29538REV-A4).
There, the MQS pins are not connected to any hardware output or filter.
What HW is needed to run this demo?
I don't have the schematic of A4. But i supposed that it should be samiliar with EVKB. please find page 9, there is a mark: SPDIF INTERFACE. There are the circuit of SPDIF but you need to mount someting before using because most of this circuit are DNP.
