EK-TM4C1294XL: Tivaware SD Card example

Part Number: EK-TM4C1294XL

Hello all,

I'am using EK-TM4C1294XL launchpad for my project development. I need to read /write my ADC data to/from a SD card  and for that I've been following the SD Card Example in Tivaware.

 The example is to read the contents of the SD card on a TFT display.  Is there any video/pictures which TI has made available regarding that example as they have done for QS-Weather application.

Looking at small video actually helps understand the code . I learned the keyboard widget by referring to the QS weather app video and its code together and it took me just couple of minutes to implement that!!

I know TI cannot make videos of every example they have in Tivaware  , but Is it possible for the SD card example ? If not video then screenshots/pictures would also help!

    You'd probably want to, "Selectively "write" (certain) content of the SD card to the TFT display."     It is (only) after such, "Writing to the TFT" - that you can "display" such content.

    Would it not prove best to follow this procedure:

    • master the set-up/config. of the ADC
    • master the transfer of ADC data to MCU Ram
    • master the (proper) "write (then read)" of such Ram data to/from the SD card
    • master the transfer of data from MCU RAM to the display
    • properly set-up/config. the TFT display    (initialization & load of the (multiple) TFT registers prove critical)

    You correctly doubt the existence of such detail w/in (any) vendor video.    By "breaking the greater whole" - into such limited, constituent parts - your task is made more measurable - AND easier.

    Investigation - targeting a far, "broader spectrum" of (potential) resources proves likely to aid your effort.    (you may find reasonably "exact" (modeled) guides - to each of the listed parts (above) - by searching among "many" ARM vendors - not just one...)     (and that proves a (near) constant - most always true - thus often "speeding, easing, enhancing" your efforts...)
