LAUNCHXL-CC1350: SPI E-paper module, does it conflict with external flash process?

CC1350 has two SSI momules (please see the "Synchronous Serial Interface" section in http://www.ti.com/lit/ug/swcu117h/swcu117h.pdf so if you are worried that you have a conflict, you can use two SPIs. 

Hello TER, 

After further debugging, I found the problem was caused by hitting memory limits.

The problem is the e-paper driver code has to allocate a large array to store the value of each pixel, then write this array to the E-paper display via SPI interface. This array is of size several KB bytes and scales with the size of the display (can go to several 10s of KB), my code is something like:

uint8_t image[5000];      //the big array causing the problem

foo(image);               // doing some manipulations on this array using the e-paper driver from waveshare

for (int i=0; i<5000; i++)
{     
       spi_write(epaper_spi_handler, image[i]);        // writing everything to the display via spi 
}

Question: 

- Can I use an external Memory(RAM/FLASH/...etc.) with CC13x0 to "store & do the manupilations" on this array, then send it as shown in the code?

Thanks,

I have no first hand experience with this but it sounds like a method that should work since reading from flash and pass the data on to the SPI should not use a lot of memory on CC13x0.

Thank you, 

I'd appreciate if you can recommend a TI example or so.

We don't have examples for this type of application but to access an external memory you can use: http://dev.ti.com/tirex/explore/node?node=AFn.XguRpPWlL0sX7PHeqg__eCfARaV__LATEST
