How to use UART in sigmastudio for sharc along with SPI?

Question asked by liangbread on Feb 18, 2018

Hi everyone,

 

   I'm now using SPI as the default communication interface.Now I prefer to add a UART interface for sending out some commands and data from 21489 periodically.

 

   However it seems something wrong with the UART enabled,and the SPI interrupted doesn't work.Even if  I putting a breaking point in the SPI callback function and debugging the program in debug mode,as long as the UART is enabled,the program will not stop int the breaking point with controlling command sending out from MCU controller.All in all,if UART is enabled,the SPI cannot receive any command from host controller.By the way,my sigmastudio for sharc version is 2.0.0.

 

Best Regards,

Liang.
