I have an SPI external device that communicate through SPI ( registers and so)
I want to operate the KW40Z in SPI master mode where i will be able to write and read 8 bytes.
I dont need the dspi package that do transfer of data from side to side, just the HAL.
My questions are:
1. is there an example how to do that simple work , because while investigating the subject i see that the SPI device is not linked and its under this define:
FSL_FEATURE_SOC_SPI_COUNT which is 0.
This define close all the SPI HAL Device.
The current options i see now is to dig into the code of the API , enable the SPI and use the Hal_WriteData and ReadData
And configure the SPI to use as Master for external device.
It will be nice if NXP will provide an example project , that is mission is to enable SPI Master and read and write data to the HAL, No interrupts , no fifo , nothing, just read and write directly to the SPI.
