Hey,

I need help. I need to activate the GPIO pin on the SRB and control using the NRB. I have no idea how to do this   can anyone help me?

You don't mention what software stack you are using... Simple MAC, 802.15.4MAC, or ZigBee BeeStack.

If you are using ZigBee BeeStack use this:

void Asp_PortReq(uint8_t portWrite, uint8_t *portValue);

If not, you need to write the values directly to the ABEL registers 0x3F.  See MC1321xRM (reference manual).

NOTE: Don't foget to set the DDR (Data Direction Register) before hand (during initialization).

If you are using ZigBee BeeStack use this:

void    Asp_DdrReq(uint8_t directionMask);

If not, you need to write the values directly to the ABEL registers 0x0B.  See MC1321xRM (reference manual).

WARNING:  Messing with the radio's GPIO can cause big problems if you are not careful to avoid the I/O used to interface to the main processor.  See MC1321xRM (reference manual).

Hey,

Thanks for the reply. I'm using the Freescale Beekit. For the solution, i am trying to control the GPIO port to be HIGH (1) or LOW (0) such that this could be connected to my hardware.

I am using the 1321XNSK with one NCB board and 2 SRB board. How can I control this? i've tried looking ath eht MC1321XSRB header file but i dont understand the the pin.. ie MC13192_RESET which has been redefine from PTDD_PTDD3. I do not find this pin anywhere on my data sheet.

Please Help..

using Codewarrior IDE version 5.9.0

The code below is not tested... but something like this should work:

Code:

#include "AppAspINTERFACE.h"// inside of init routineAsp_DdrReq(0x08);   // make GPIO4 an output// to write logic HIGHpVal = 0x08;  // logic HIGH on GPIO4Asp_PortReq(TRUE, &pVal);  // write pVal to GPIO// to write logic LOWpVal = 0;  // logic LOW on GPIO4Asp_PortReq(TRUE, &pVal);  // write pVal to GPIO
