Hi Guys!

I working with my device (based on Sample Light w Zstack Z-Stack Home 1.2.2a.44539), w/ a SimpleDescriptionFormat as ZCL Basic On/off, to use 4 GPIO ports (P1_4, P1_5, P0_5 and P0_4), all those have eletric pin avaiable for use. My idea is that when my device received ZCL cmd On/off all those GPIO ports answer (High-1 or Low Level-0, on or off).

To do that i wrote those code in onoffCB funcition:

// Turn on the light
if ( cmd == COMMAND_ON )
{
zclTeha0002_OnOff = LIGHT_ON;
P1_4 = 1;
P1_5 = 1;
P0_5 = 1;
P0_4 = 1;
P0_3 = 1;
P0_2 = 1;
}
// Turn off the light
else if ( cmd == COMMAND_OFF )
{
zclTeha0002_OnOff = LIGHT_OFF;
P1_4 = 0;
P1_5 = 0;
P0_5 = 0;
P0_4 = 0;
P0_3 = 0;
P0_2 = 0;
}

After my device received the cmd on/off, from the gateway, just P0_5 responds to the commad and changs its level stats ( on-1 and 0ff-0). I didnt not find any code that blocked the another ports (p1_4, P1_5, P0_4, P0_3 and P0_2).

Anybody have any idea?

Do you also set PxSEL to disable peripheral function and PxDIR to GPO for P1_4, P1_5, P0_5 and P0_4?

Hi Mr Yikai, thanks a lot for your assistance!

I´m using the default DMA configuration (_hal_uart_dma.c) as you can see bellow:

#if (HAL_UART_DMA == 1)

#define PxOUT P0

#define PxIN P0

#define PxDIR P0DIR

#define PxSEL P0SEL

#else

#define PxOUT P1

#define PxIN P1

#define PxDIR P1DIR

#define PxSEL P1SEL

Is this configuration you mentioned?

Mr Yikai,
I found this configuration example on hal_board_cfg.h:

/* Select peripheral function on I/O pins but SS is left as GPIO for separate control. */\
P1SEL |= 0xE0; /* SELP1_[7:4] */\
/* P1.1,2,3: reset, LCD CS, XNV CS. */\
P1SEL &= ~0x0E; \
P1 |= 0x0E; \
P1_1 = 0; \
P1DIR |= 0x0E; \

I think is this configuration that you asked me. If is that, please would you can advise me how to set my configuration?

You have to use the following code:

P0SEL &= (~(BV(4)|BV(5)));
P1SEL &= (~(BV(4)|BV(5)));
P0DIR |= (BV(4)|BV(5));
P1DIR |= (BV(4)|BV(5));

Mr Yikai,

on _hal_uart_dma.c or hal_board_cfg.h ?

In your application init function.

Hi Mr. Yikai.

void zclTeha0002_Init( byte task_id )
{
zclTeha0002_TaskID = task_id;

P0SEL &= (~(BV(4)|BV(5)));
P1SEL &= (~(BV(4)|BV(5)));
P0DIR |= (BV(4)|BV(5));
P1DIR |= (BV(4)|BV(5));

.....

Now is running very well!

You are the BEST!

Thanks a lot!!!!
