Hi @kerryzhou
非常感谢你的回复。
请问如何导入AUD的SDK？好像没有办法通过这个界面导入IDE。
我目前只是下载了你给我链接中的压缩包。
我只是把I3C-master_read_sensor_icm42688p该文件夹中的
这个C文件移植到了我的工程，目前没有办法正常运行。
是因为我没有把完整的SDK文件导入其中么？
Hi @kerryzhou
谢谢你的回复。
我根据文档内容，将压缩包拖入installed SDK，会出现如下图所示的错误。我把原来的SDK（不是MIMXRT685-AUD-EVK的SDK）删除，重新导入新的SDK也会报下面的错误。
报错框中的ERROR LOG打不开
Thanks
Hi @kerryzhou
thanks for your reply.
I use EVK-MIMXRT685 , not MIMXRT685-AUD-EVK.
Another question:
int main(void)
{
uint8_t result;
i3c_master_config_t masterConfig;
uint8_t fifodata[16];
i3c_master_transfer_t masterXfer;
/* Attach main clock to I3C, 396MHz / 4 = 99MHz. */
CLOCK_AttachClk(kMAIN_CLK_to_I3C_CLK);
CLOCK_SetClkDiv(kCLOCK_DivI3cClk, 20);
BOARD_InitBootPins();
BOARD_InitBootClocks();
BOARD_InitDebugConsole();
PRINTF("\r\nI3C master read sensor data example.\r\n\r\n");
I3C_MasterGetDefaultConfig(&masterConfig);
masterConfig.baudRate_Hz.i2cBaud = EXAMPLE_I2C_BAUDRATE;
masterConfig.baudRate_Hz.i3cPushPullBaud = 12500000U;
masterConfig.baudRate_Hz.i3cOpenDrainBaud = 2500000U;
masterConfig.enableOpenDrainStop = false;
I3C_MasterInit(EXAMPLE_MASTER, &masterConfig, I3C_MASTER_CLOCK_FREQUENCY);
/* Create master handle. */
I3C_MasterTransferCreateHandle(EXAMPLE_MASTER, &g_i3c_m_handle, &masterCallback, NULL);
PRINTF("i3cPushPullBaud: %d\r\n", masterConfig.baudRate_Hz.i3cPushPullBaud);
PRINTF("i3cOpenDrainBaud: %d\r\n", masterConfig.baudRate_Hz.i3cOpenDrainBaud);
PRINTF("Broadcast CCC DISEC (DISHJ + DISMR + DISINT): ");
display_ccc_status(i3c_ccc_disec_b(CCC_DISEC_BYTE_DISHJ | CCC_DISEC_BYTE_DISMR | CCC_DISEC_BYTE_DISINT));
PRINTF("\r\n");
PRINTF("Broadcast CCC RSTDAA: ");
display_ccc_status(i3c_ccc_rstdaa_b());
PRINTF("\r\n");
i3c_demo_setdasa(0x68, 0x27);
When I use this demo to get the dynamic address. the code can't jump this while loop.
Could you help me ? thanks
Hi @melanie ,
MIMXRT685-AUD-EVK is similar to the MIMXRT685-EVK board, just the AUD-EVK on board contains the ICM-42688 sensor.
So, please still check my mentioned SDK code at first, then you can port the related I3C demo to your own project and test.
Please check my mentioned SDK code at first, thanks.
Best Regards,

Hi @kerryzhou
Thanks for your reply
I check the SDK you mentioned.
I use similar sensor to test the code. But there are some error. could you help me?Thanks
Hi @melanie ,
Talk about my experience for I3C.
I think, just check the code debug result is not enough, do you have the logic analyzer? It's better to contains the I3C function, then check the bus, it will helps you to find the detail area issues.
About the testing, you can download the SDK and test it on the EVK directly, just run it in RAM, not the flash, as I know EVK and audio EVK used external flash have differences, others should be similar.
About the connection to your sensor, make sure you add the external pull up.
Then test the I3C wave, whether it has response or not? Check the DAA works or not?
The wave should like this:
I checked my previous wave, but seems my logic tool meet issues, it deletes all my saved old 42688 I3C wave, so can't share you directly now. Maybe you need to test it by yourself.
If you have the AUDIO-EVK, that will be more useful to you.
Best Regards,
kerry
