ADS1224 interface

I have to interface ADS1224 with RM48l90pge

I think to do this with spi2 pins which are sclk and somi pins for communication and cs0 and cs1 for mux controlling (behaves as IO pins)

to recive th data I use 3 data formats

FMT0 as a 16 bits width recived data

FMT1 as 9 bits data for complete cycle

and FMT2 of 2 bits for enable the callibration cycle

I have two problems

1.how can I use the ISR

the ISR is configured for RXINT for ISR enable and spigetdata function for reading data in ISR mode

but when I use the function there is no RXINT ISR

2.There is a way to recive an ISR on somi pin when the falling edge from the ADS happened which tell me that there is new data ?

Or I have to use on of GIOA pins to recive the ISR ?

Yehonatn,

Apparently you are posting similar question on multiple thread.
This is a little bit confusing.

MIBSPI supports interrupts and DMA requests.
Like I've replied in another of your post, all the details about using interrupt on MIBSPI are available in the following document:

TMS570LS2x Users Guide. spnu489c.pdf (chapter 14.6 Interrupts)

Please have a look and let me know if you have any question.

Best Regards,

Jean-Marc

Here I post what I have done

I want to use spi2 as simple SPI without buffer or string transfer and recive an ISR when RX cycle is done

so What I did wrong ?

The fastest way will be if

maybe you will send me a demo for both cases (mibspi and spi) with ISR
