Zstack Serial Communication

Objective: To realize the serial communication between PC and CC2530, select P0-2,p0-3

Function: The PC sends arbitrary string to the microcontroller, the microcontroller then returns the data to the PC computer

First, the execution process: 1. Open the Zmain function, which is the main function of the entire zstack execution
2. Locate to Osal_init_system (); This function is the system initialization function (Zstack embedded in the Osal operating system)
3.go to define of Osal_init_system; open osal.c file, find Osalinittasks (); (Task initialization function) Start the task,
Registration tasks:
Const PTASKEVENTHANDLERFN tasksarr[] = {
Maceventloop,//mac Task Cycle
nwk_event_loop,//Network Layer Task function
hal_processevent,//Hardware layer Functions
#if defined (mt_task)
mt_processevent,//serial port support layer definition
#endif
aps_event_loop,//Application Support Layer Task event function
#if defined (zigbee_fragmentation)
Apsf_processevent,
#endif
zdapp_event_loop,//Device Object layer function
#if defined (zigbee_freq_agility) | | Defined (zigbee_panid_conflict)
Zdnwkmgr_event_loop,
#endif
genericapp_processevent//self-defined task handler function
};

Initialize the task:
void Osalinittasks (void)//Add a task ID for each process to use as a lookup task
{
Uint8 TaskID = 0;

Tasksevents = (UInt16 *) osal_mem_alloc (sizeof (uint16) * taskscnt);
Osal_memset (tasksevents, 0, (sizeof (uint16) * taskscnt));

Mactaskinit (taskid++); task ID number for//MAC layer
Nwk_init (taskid++);//Network ID Assignment
Hal_init (taskid++);//Hardware ID Assignment
#if defined (mt_task)
Mt_taskinit (taskid++);
#endif
Aps_init (taskid++);
#if defined (zigbee_fragmentation)
Apsf_init (taskid++);
#endif
Zdapp_init (taskid++);
#if defined (zigbee_freq_agility) | | Defined (zigbee_panid_conflict)
Zdnwkmgr_init (taskid++);
#endif
Genericapp_init (TaskID);//Add ID for your task
}

The red color of the word is what we need to add
4. New COORDINATOR.C (Coordinator)
Port registration, initialization, task registration, task initialization, serial port initialization
uartconfig.configured = TRUE; 2x30 don ' t care-see UART driver.
Uartconfig.baudrate = hal_uart_br_115200;
Uartconfig.flowcontrol = FALSE;
Uartconfig.flowcontrolthreshold = 64; 2x30 don ' t care-see UART driver.
uartConfig.rx.maxBufSize = 128; 2x30 don ' t care-see UART driver.
uartConfig.tx.maxBufSize = 128; 2x30 don ' t care-see UART driver.
Uartconfig.idletimeout = 6; 2x30 don ' t care-see UART driver.
uartconfig.intenable = TRUE; 2x30 don ' t care-see UART driver.
uartconfig.callbackfunc = RXCB; (Serial receipt function)
Haluartopen (0, &uartconfig);
static void Rxcb (Uint8 port,uint8 event)
{
unsigned char uartbuf[10];
unsigned char len;
Len=haluartread (0,uartbuf,10);
if (len)
{
Haluartwrite (0,uartbuf,len);
len=0;
}
}

5. Implement serial port sending:
Read the data sent by the PC via Haluartread and put it in the Uartbuf
Send data to PC via Haluartread
6. Compile the downloader into CC2530
