CC2650DK change LCD_CSN pin

Tzuyu,

When you modified your board did you change the connection for Board_KEY_UP also?  By default Board_KEY_UP is wired to IOID_19. Snip from CC2650DK_7ID.h:

...
#define Board_KEY_SELECT                    IOID_11         /* P1.14 */
#define Board_KEY_UP                        IOID_19         /* P1.10 */
#define Board_KEY_DOWN                      IOID_12         /* P1.12 */
#define Board_KEY_LEFT                      IOID_15         /* P1.6  */
#define Board_KEY_RIGHT                     IOID_18         /* P1.8  */
/* LCD  Board */
#define Board_LCD_MODE                      IOID_4          /* P1.11 */
#define Board_LCD_RST                       IOID_5          /* P1.13 */
#define Board_LCD_CSN                       IOID_14         /* P1.17 */
...

If that is not the problem, please reply back with the version of TI-RTOS you are using, and details of both board and software changes you’ve made.  Also, any debugging details that could provide more information.

Thanks,
Scott

I mark all Button Board:

It is hard to know what might be going wrong without a lot more information.

After changing the pin defines did you modify the PIN_Config structures being passed to PIN_init() and PIN_open()?  

Are you using the LCD example that comes with TI-RTOS?  If yes, can you attach the files you modified?

What version of TI-RTOS are you using?

Was the LCD working before the hardware modifications?

What other *hardware* modifications have you made?

When you run the application, do you get any errors from any APIs?  Or does the CPU get stuck at a certain point?    Are there any other new issues besides the LCD not displaying anything?...

Thanks,
Scott

in Board.h , I change Board_LCD_CSN IOID_19 (original is IOID_14)

5078.Board.h

3617.Board.c

OK, thanks, I see that you did modify the PIN_Config passed to PIN_init().  Did you also modify the PIN_Config passed to PIN_open()?

Can you please respond to these questions I posted before?  To help you I need you to provide more information...

I use SimpleBLEPeripheral project  , and guess LCD function is complete.

and I do experiment on CC2650DK , this is my SimpleBLEPeripheral.c:

0677.SimpleBLEPeripheral.c

So if you aren’t modifying the hardware, do you still have any issues?  Can you run the lcdSmartRF06EB example?
