Overview
========
The sai_interrupt_transfer example shows how to use sai driver with interrupt:
In this example, one sai instance playbacks the audio data stored in flash/SRAM using interrupt.
Toolchain supported
===================
- IAR embedded Workbench 9.30.1
- Keil MDK 5.37
- GCC ARM Embedded 10.3.1
- MCUXpresso 11.6.0
Hardware requirements
=====================
- Mini/micro USB cable
- EVK-MIMXRT1020 board
- Personal Computer
- Headphone
Board settings
==============
No special settings are required.
Prepare the Demo
================
1. Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
2. Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
3. Download the program to the target board.
4. Insert the headphones into the headphone jack on EVK-MIMXRT1020 board.
5. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
================
When the demo runs successfully, you can hear the tone and the log would be seen on the OpenSDA terminal like:
~~~~~~~~~~~~~~~~~~~
SAI example started!
SAI example finished!
~~~~~~~~~~~~~~~~~~~
Note:
To debug in qspiflash, following steps are needed:
1. Select the flash target and compile.
2. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
3. Start debugging in IDE.
- Keil: Click "Download (F8)" to program the image to qspiflash first then clicking "Start/Stop Debug Session (Ctrl+F5)" to start debugging.
