Part Number: TM4C1294KCPDT

We are planing to use TM4C1294 to drive LED DMD module via 4bit SPI output.

So, Does TI have any example project 4bit SPI for TM4C1294 ? Thank you.

Have you tried modifying an existing example for four bits? If so, what issues did you happen across?

Hi Robert,
Which existing example ? I cannot find existing example for 4bit SPI. Could you please help to share that example ? Thank you.

Hello CCphi,

We don't have any example for 4-bit SPI mode. What Robert is suggesting is to take the 8-bit example from [Install Path]\TivaWare_C_Series-2.1.4.178\examples\peripherals\ssi and modify it for your 4-bit needs, which I agree would be the best path forward for you. You may also try searching the forums in case any others tried this and posted working code.
