Implementation of UART Driver APIs

Sankari Mirasi

Other Parts Discussed in Thread: CC3200

Hi,

I am working UART driver with TI RTOS in CC3200.

I am working on UART_Echo example and I wants to know how UART interrupt is handled here either polling mechanism or interrupt based. How to check this here?

I also wants to know how UART_read() and UART_write() was implemented in UART driver. In UART.h, I am able to see the function declarations only not definitions.

Please share documents which will explain about UART drivers fully.

Hi Sankari Mirasi,

TIRTOS ships the driver source files. You should be able to see UART sources in your installation folder.

For example, I see the driver sources here on my machine:

C:\ti_ccs6.0\CCSv6.0.0.00190\tirtos_simplelink_2_01_00_03\packages\ti\drivers

C:\ti_ccs6.0\CCSv6.0.0.00190\tirtos_simplelink_2_01_00_03\packages\ti\drivers\uart

Hi Steve,

Thanks for your response.

I also wants to know how UART interrupt is handled here either polling mechanism or interrupt based. How to check this in CCS?

I believe both interrupt and polling modes are supported. In particular, for polling mode there are APIs such as UART_readPolling().

Please refer to the following documents for more details (located in your TI RTOS install):

Were you able to get past the above issue? If so, would you mind please marking the post as "verified" for closure?

Thanks,

Steve
