So far, this is what I have tried:
main()
{
I2C_MasterTransferCreateHandle(I2C0, &g_m_handle, i2c_master_callback, NULL);
readcodec();
}
readcodec()
{
uint8_t data[2];
i2c_master_config_t masterConfig;
I2C_MasterGetDefaultConfig(&masterConfig);
masterConfig.baudRate_Bps = I2C_BAUDRATE;
sourceClock = CLOCK_GetFreq(I2C0_CLK_SRC);
I2C_MasterInit(I2C0, &masterConfig, sourceClock);
i2c_master_transfer_t masterXfer;
memset(&masterXfer, 0, sizeof(masterXfer));
masterXfer.slaveAddress = 0x1AU;
masterXfer.direction = kI2C_Read;
masterXfer.subaddress = 0x2;
masterXfer.subaddressSize = 0;
masterXfer.data = &data;
masterXfer.dataSize = 1;
masterXfer.flags = kI2C_TransferNoStopFlag;
I2C_MasterTransferNonBlocking(I2C0, &g_m_handle, &masterXfer);
/* wait for transfer completed. */
while ((!nakFlag) && (!completionFlag))
{
}
nakFlag = false;
if (completionFlag == true)
{
completionFlag = false;
find_device = true;
}
}
This is based out of the Accelerometer demo application that was part of the KSDK bundle.
I am trying to read DA7212's status register. So far, no I2C interrupt itself is getting generated, and the code is stuck at while(!nakFlag). Please help.
Is there a sample application for using DA7212 in the FRDM K66 board?
