SPI slave KEA-128

[vigneshbalaji]

I want an example code for SPI_Slave in KEA-128? If you can say me just the register settings it will be great.

Hi VIGNESH BALAJI,

    Please download the FRDM-KEA quick start package from this website:

http://www.nxp.com/assets/downloads/data/en/board-support-packages/FRDM-KEA-QSP.zip 

 Then you can find the SPI slave code from folder:

FRDM-KEA-QSP\Quick Start Package v5\SDK Drivers and Code Example Projects\FRDM-KEAZ128\Driver Test SW for KEAZ128\Driver Test SW for  KEAZ128\FRDM_KEA128_SPI_Slave

  The driver is nearly just control the register, it is not difficult to understand.

Wish it helps you!

Have a great day,
Kerry

SIM_PINSEL0 |= SIM_PINSEL_SPI0PS_MASK; /* Selected PTE0,PTE1,PTE2 & PTE3 ******/
SIM_SCGC |= SIM_SCGC_SPI0_MASK; /* Clock enabled to SPI0 ***************/
SPI0_C1 |= SPI_C1_SPE_MASK /* Enable SPI **************************/
| SPI_C1_MSTR_MASK /* SPI as Master ***********************/
| SPI_C1_CPHA_MASK; /* CPHA = 1 ****************************/
SPI0_BR = 0x10; /* Set baud rate ***********************/ // 5 Mhz
SPI0_C2 &= ~SPI_C2_MODFEN_MASK; /* Disable MODFEN **********************/\

int main(void){
     Clk_Init();
     SPI_init();

 for(;;)  {
    SPI_read();
