nodeMcu API Instruction

中文版本 ###version 0.9.2 build 2014-11-20 ###change log: 2014-11-20
fix tmr.delay to support more than 2s delay, may cause bacon time out, lost connection to AP.
add tmr.wdclr to clear watchdog counter in chip, use in long time loop.
fix UDP part of net module.
add a timeout para to createServer(net.TCP, timeout).

2014-11-19
add adc module, use adc.read(0) to read adc value, no tests made.
add wifi.sta.getap() api to wifi.sta module, to get ap list.

2014-11-18
bug fixed: net.socket:connect() has no effect.

2014-11-18
bug fixed: as a tcp server, the connection can't closed with :close().
tcp server: inactive connection will closed by server in 30s (previously 180s).
add a test api node.input() to put lua chunk into lua interpretor, multi-line supported.
add a test api node.ouput(function) to direct serial output to a callback function.
file.readline() now returns line include EOL('\n'), and returns nil when EOF.

2014-11-12
full version firmware

2014-11-11
add file.seek() api to file module
now max 6 pwm channel is supported

2014-11-10
change log module to file module
now file operation support multiple read/write
for now file module only allowed one file opened

add log module
modify wifi module api
modify node.key long_press and short_press default function
