S32k144 SPI Transfer and Receive.

[akhilranga]

Hello there, I tried different examples like FlexIO SPI from RTM SDK and etc.

But that was not helpfull for my case. 

I am trying to send the following message frame as a master to the slave. 

uint8_t Inventory_cmd[5] = {0x03,0x2F,0x01,0x2D}

After the slave receives this message it makes its IRQ pin high then this Hight state of IRQ pin is acknowledged by the master and it will send the remaining dummy bytes to completly receive the responce frame. So, please help me to identify which SPI transfer function and recive function will help me to acheive this. Please help

Hi @akhilranga 

Sorry for any inconvenience this may cause, but there is no example code with the functionality you are looking for, the available ones are found with the SDK or with RTD.
