FT-6200

• FT-6200 High-Power ZigBee Starter Kit
• FT-6250 Base Development Board
• FT-6251 Sensor Development Board
• Jennic SDK
• JN-SW-4027 SDK with CLI
• DIO
• Ft6200-Patch-ba-1v0.exe
• FontalBSP

Environment

• When you build up your environment
• BoardAPI
• FontalBSP
• FontalButton, FontalLED
• HardwareAPI
• Stack 802.15.4 MAC
• Application Queue API
• Service Access Point AppApi.h
• Access functions and structures used by the
  application to interact with the Jennic 802.15.4
  stack

Blink sample

• This application uses a TickTimer to toggle the
  LEDs
• HardwareAPI
• TickTimer
• FontalBSP
• led_init()
• led_toggle(LED0)
• led_toggle(LED1)

6
Integrated peripherals API

• This API was previously known as the Hardware
  Peripheral Library or the Hardware API
• The functions are defined in AppHardwareApi.h
• u32AHI_Init(void)
• This should be called after every reset or
  wake-up and before any other AHI calls are made
• We can see that in sample codes in Blink
  application

7
Startup

• AppColdStart
• This is the main entry point for the application
  just like main(), called after the ROM-resident
  boot loader has finished
• AppWarmStart
• Required as the main entry point for a warm start
  (i.e. CPU has been powered down then restarted,
  but the RAM contents were retained)

8
TickTimer

• vAHI_TickTimerConfigure(E_AHI_TICK_TIMER_RESTART)
  
• vAHI_TickTimerWrite(0)
• vAHI_TickTimerInterval((1610001000)/2)
• vAHI_TickTimerIntEnable(TRUE)
• bAHI_TickTimerIntStatus()
• vAHI_TickTimerIntPendClr()

9
LED control

• include ltFontalLED.hgt
• led_init()
• led_on(LED0)
• led_off(LED1)
• led_toggle(LED0)

Lab

• Counter
• Modify the Blink application to an counter
  application
• FT node has 2 LEDs
• Count from 0 to 3
