I am trying to add SPI to Project Zero project. I followed the developer's guide of CC2640 and CC2650 SimpleLink™ to add a driver.
I have done the following steps:
add Board_SPI0_CSN pin to pin config table
modify .csnPin= Board_SPI0_CSN
in projectzero.c file
#include <ti/drivers/SPI.h>
/* SPI driver handles */
static SPI_Handle spiHandle;
static SPI_Params spiParams;
in static void ProjectZero_init(void) function
// ******************************************************************
// SPI initialization
// ******************************************************************
Log_info0("SPI initialise start");
SPI_Params_init(&spiParams);
spiHandle=SPI_open(CC2650_LAUNCHXL_SPI0,&spiParams);
Log_info0("SPI initialise done");
From my log:

I noticed that SPI:(@40000000) CPU freq: 48000000; SPI freq to 1000000 keep on repeating is due to spiPostNotify function.
Then when I perform a simple SPI transfer:
uint8 txbuf[]={0,1,2,3,4};
uint8 rxbuf[5];
SPI_Transaction spiTransaction;
spiTransaction.arg=NULL;
spiTransaction.count=5;
spiTransaction.txBuf=txbuf;
spiTransaction.rxBuf=rxbuf;
SPI_transfer(spiHandle,&spiTransaction);
the launcher pad is not responding anymore even after I press the reset button.
Please give me some advice.
Thanks.
