I am using TLC5916-Q1 LED Driver for switching of 8 different color led's and in application,switching takes place at fast rate. As per datasheet, interfacing is as shown:
Datasheet: http://www.ti.com/product/TLC5916-Q1
For interfacing SDI, CLK pins are used. I have seen one application where these pins are assigned to SPI pin ( SDI--> MOSI and CLK-->SCLK)
My question is can I assign it ( OPTION 1 ) to I/O pins or ( OPTION 2 ) to I2C pins.
What are considerations while assigning these pins to controller?
Thank you.
