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

Hi

Suggest that utilize attached files for hardware and software configuration,especially for UART speed /SPI communication timing/initialize of the Bridge IC.

Hi ,

I am trying to use this ic for i2c interface with my nxp t1024rdb processor. we need an extra debugger port and i have to use it as a serial console. I see here the document for the SPI interface is there any similar document for i2c interface. Any suggestion on how should i proceed for it.

Regards

Parth
