TLC5926-Q1: SPI communication between IC and Raspberry Pi

Hi, Jacob

I hope this picture can help you well.

In CLK15, SDI is high and the OUT0 is ON.

In CLK14/13, SDI is low and the OUT1/OUT2 is OFF.

yes, thank you for the speedy response. This was the main source of information we have used so far (along with the truth table (table 4) below) but I am still not sure where to find information on how to control LEDs connected to other TLC5926 chips with SPI.

Other types of chips can be daisy changed from SDI to SDO and programed with a series of data. For example, if I had N chips connected together I could program the outputs by sending a 32 bit start frame, N number of 32 bit frames to control each chip, and a 32 bit End frame. this data set then can loop or vary to animate the outputs.

My goal for the TLC5926 would be to send data to only one TCL5826 SDI and have that first chip send data though the SDO to the next chip and so on. This is where I am struggling to find Information. How can I encode SPI information from the raspberry pi to the SDI of the first TLC5926 to control a series of chips and their respective outputs. 

Thank you!
