TMS470MF06607: TMS470MF06607 SPI driver

Hi,

i am using TMS470MF06607 microcontroller.

i am trying to do SPI communication on this controller with ADS1220 ic.

For generate the MIBSPI1 driver i am using the HALCOGEN.  There is no example for this micro.

i didn't change any default setting in the HALCOGEN. only one change i did it in MIBSPI1 GROUP 0-7   , here i changed that length of the buffer from zero to eight.

i enabled the vim channel interrupt also.

what ever the code i written for the MIBSPI1  it's not working. because i checked that clock pin. i did not get the continues pulses.

i copied my code in down side. if any problem in my program means please help to me to correct it.

otherwise if any example code is available for TMS470MF06607     spi communication ( MIBSPI1) can you please share that one to me.

program:

//#include "sys_core.h"

//#include "sys_vim.h"
