Interfacing 32x16 Dot Matrix Display to TM4c1294ncpdt

Post by JoeClark » Sat Nov 18, 2017 10:00 am


Am trying to interface 32x16 DMD(single colour) to TM4c1294ncpdt controller. The 32x16 display driver is for aurdino boards but i want to use it for TM4c board.The communication is SPI.The Dot matrix display is connected to tiva board using DMDCon connector which has 16 pins. The display board has the Foll pins as shown in attachment
1) A and B pins to select row(as only 128 leds can be on out of 512)
2)R acts as MOSI
3)there are 2 pins CLK and SCLK which am not sure to which I/O it should be connected.Clk is PIXEL clock and Sclk is like strobe pin
4)OE pin is for controlling all led high /low at a time (output Enable)
5)pin C,G and D are NC and remaining are grounded.
Have written the code to transfer some data on DMD but i am unable get any data.

Please help.

I didn't find the right solution from the Internet.
