How to define UART for show the debug log in CC2650 ?

Other Parts Discussed in Thread: CC2650, CC2640, CC2650STK

I am new to TI CC2650. I am developing in SimpleLink with SimpleBLEPeripheral. I want to show the log via UART.

The Code in Board.h is like the following:

/* UART Board */
#define Board_UART_RX IOID_1 /* RF1.7 */
#define Board_UART_TX IOID_0 /* RF1.9 */
#define Board_UART_CTS PIN_UNASSIGNED
#define Board_UART_RTS PIN_UNASSIGNED

And I am sure the UART of HW us connect to the IOID_1 and IOID_0.

But it did not show any log when I using Putty to open the COM PORT.

Does some one can direct me? Thanks in advance.

Hello,

I would suggest you take a look at the Project Zero BLE example as it includes a debug UART interface. You can find a link to Project Zero on the TI BLE Wiki.

Best wishes

Hi

I define the UART like the following:
/* UART Board */
#define Board_UART_RX IOID_1 /* RF1.7 */
#define Board_UART_TX IOID_0 /* RF1.9 */
#define Board_UART_CTS PIN_UNASSIGNED
#define Board_UART_RTS PIN_UNASSIGNED

I am sure the HW is connect to the above UART Pin.

Do you follow the steps in section 6.3.2 UART in SWRU393_CC2640_BLE_Software_Developer's_Guide.pdf?

Yes , I have try. The doc says the Board_UART_RX is IOID_2 and the Board_UART_TX is IDIO_3. But there does not has IDIO_3.

So I change it to

#define Board_UART_RX IOID_2
#define Board_UART_TX IOID_3

But it seen not working.

What do you mean "But there does not has IDIO_3?" Which CC2650 HW do you test this UART thing? CC2650DK or CC2650 LaunchPad or CC2650STK?

Hi I use the SmartRF06 + CC2650EM. And I have search in SimpleBLEPeriphal project. It does has IDIO_3. Only has IOID_3.

Sorry for the typo in the document. Thanks for pointing it out.

Have you tried our simplelink academy? It's a nice training tool for user to get familiar with TI BLE stack solution.
You can download the simplelink academy training here.

Output data from UART to PC is also included in the training session. The training contains different HW platform(CC2650DK, CC2650 Launchpad, CC2650 sensortag).

Simplelink academy can be downloaded here :
