RTOS: CC2530 UART transportation support

Other Parts Discussed in Thread: CC2530, Z-STACK

Tool/software: TI-RTOS

Hi everyone!

I'm a beginner of using CC2530. I want to build a UART project with Z stack's libraries. I've already installed Z stack 3.0.1 and read the description of UART's functions in HAL Driver API document.

But I got stuck with using these functions to build my project.

Could anyone help me to do this? (the setting in C/C++ Compiler, more specifically in Preprocessor section and how to add related libraries including in the Stack (literally how to use this Stack ^^)) ?

Thanks in advance.

But I don't know how to add suitable libraries and header files supporting these UART's functions.
On top of that I'm using IAR Embedded WorkBench. I got difficulties with setting Preprocessor in Options -> C/C++ Compiler, section "Define Symbol (one per line) ".
Could you help me with these promblem?

1. You should add hal_uart.c into project. You can drag and drop it to there.

2. What do you mean "got difficulties with setting Preprocessor in Options -> C/C++ Compiler, section "Define Symbol (one per line) "?"

I mean the red mark. What information can I put on it for UART project?

I read some examples and this section in several projects is different.

What about other relevant libraries supporting hal_uart.c? Any recommendation or document for me to get started?

I truly appreciated your support.

Sorry for inconvenience. But what is the purpose of the information in that section?

It provides global define for whole project.

Hi Chen,
I was reading the document HAL Driver API in Documents folder from Z Stack 3.0.1 about UART Services. But I don't see any function refer to parameters like parity bit or number of stop bit settings.
Please give me more information about this!
Thank you.

But I did not see these parameters in Parameters Details section . I also tried to discover the hal_uart.c and can not see any function that sets up these parameters to initialize UART protocol. I dont know why because I still find it in 9.12 Constants page 27 and no function uses them, though.
I'm getting started with Z Stack, so sorry for my inconvenience.
Thank you.

Low-level register settings are modified in the pre-compiled driver library, you can only get as far as hal_uart_[isr/usb].c in the Z-Stack Components\hal\target\ folder.

You can refer to sunmaysky.blogspot.tw/.../how-to-use-two-uart-ports-in-cc2530-z.html to know how to add defines to use UART in Z-Stack. However, you also need to read processors.wiki.ti.com/.../Optimizing_Flash_and_RAM_Usage_of_Z-Stack_for_CC2530 to reduce flash and ram usage to make it in Z-Stack 3.0.1 when you enable UART.
