SC16IS750 SPI Initialization Code

Hello,

   My name is Lucas Juttner and I am an embedded system engineer for an electric race car senior project at the University of California, Irvine. I am currently trying to use the SC16IS750 to interface with a Texas Instruments MSP430G2553 micro-controller via SPI. I have validated my SPI communication through a different chip, but I am not able to communicate via SPI with the SC16IS750. I think my problem may be from the register initializations I am setting. My goal is to constantly read from the UART RX line on the SC16IS750 chip, and send it over SPI to my micro-controller for data acquisition. The UART input should be running at 9600 baud. I do not believe an interrupt is necessary as I should just be constantly reading. Any help at all would be greatly appreciated.

 

Thank you,

Lucas Juttner
