###变更日志:
|

2014-11-20<br />
|
||||
修正tmr.delay，支持2s以上的延时，但是长延时可能会引起beacon timer out，导致与AP之间重新连接。<br />
|
||||
增加tmr.wdclr()，用来重置看门狗计数器，用在长循环中，以防芯片因看门狗重启。<br />
|
||||
修正net模块UDP无法连接问题。<br />
|
||||
createServer(net.TCP, timeout)函数增加连接超时参数设置。
|
||||
|
||||
2014-11-19<br />
|
||||
增加adc模块，adc.read(0)读取adc的值。<br />
|
||||
wifi模块增加wifi.sta.getap() 函数，用于获取ap列表。
