 +## openwrt configure for tplink 703N
 +
 +steps:
 +
 +1. buy an tplink 703N, if it is A17 version , need to download an old firmware from tplink http://service.tp-link.com.cn/download/20131/TL-WR703N_V1_121204.rar
 +2. download the bin to downgrade the firmware
 +3. download tplink specific firmware with squre factory os
 +4. flash the firmware within the web ui
 +5. after reboot, link lan with laptop, and telnet into the system
 +6. type passwd to set new passwd for root, reboot and ssh to system with new passwd
 +7. change /etc/config/wireless file and reboot to enale wifi

 +Mike,
 +I've seen exactly this problem several times on the 205 and it was generally caused by the main 'C' stack being too small or corrupted.
 +
 +http://www.freertos.org/RTOS-Cortex-M3-M4.html
 +
 +. If you are using an STM32 with the STM32 driver library then ensure all the
 + priority bits are assigned to be preempt priority bits by calling NVIC_PriorityGroupConfig( NVIC_PriorityGroup_4 ); before the RTOS is started.
 +
 +이미 NVIC_PriorityGroup_4로 되어 있네ㅣ
 +
 +스택 사이즈?
 +시스템 테스크를 2배에서 4배로 스택 크기를 수정
 + -> 그래도 죽네;; 다른때보다 3배정도는 늦게 죽는다.
 +
 +http://www.freertos.org/a00111.html
 +
 +Uart에 이걸 넣음
 +
 +vTaskSuspendAll()
 +xTaskResumeAll()
 +
 +The stack in use when you call main() is recycled for use by all interrupt handlers.
 +
 +
 +
 +---------------- 
 +
 +Heli controls are like following
 +
 +Throttle/Collective Pitch == up/down
 +Rudder == yaw, rotate left/right
 +Elevator == (bank)/fly forward/backward
 +Aileron == (bank)/fly sideways left/right
