update to sdk 0.9.4

Note: no api change, but another 2k ram gone...

opensource

So, maybe it's better let you guys to decide which module to use.

Important Re-arrange GPIO MAP due to development kit.

NEW GPIO MAP: https://github.com/nodemcu/nodemcu-firmware#new_gpio_map

Add bitwise operation module.

Modify net.socket:connect() api to accept domain name, auto DNS.

Add firmware for flash size 1Mbytes, 2Mbytes, 4Mbytes.

2014-12-12

modify wifi.xx.getip() to return nil, if ip is 0.0.0.0.

2014-12-11

1, fix uart.setup(), now setup can set pins in other mode back to uart mode.

2, add wifi.sta.status() api, to get connection status in station mode.

3, modify tmr.now() to return a uint31 rather than uint32. now-=0x80000000 if now>0x7fffffff.

2014-12-09

increase alarm num in tmr module to 7.

2014-12-08

add uart.setup(), uart.write() api.

2014-12-07

1, add ow(1-wire module), from arduino, and use same api.

2, add an 18b20 1-wire example.

3, change net.socket.send() payload max len from 256 to 1460.

4, modify gpio.mode() api, add internal pullup/float para.

2014-12-04

fix memory leak issue when input and run from console.

2014-12-02

2, modify the return of file.open, return nil if file not exist, true if opend ok.

3, move startup version display before doing the init.lua.

4, modify wifi.ap.config(), remove the restart at the end of config.

2014-11-30

1, modify the max freq of pwm module to 1000.

2, modify the max duty cycle of pwm module to 1023.

3, add uart module, uart.on("data") api to receive data from uart.

example:

2014-11-29

1, fix tmr.delay not work when delayed time < 1s.

2, fix pwm module not work when freq<77.

2014-11-25

Fix memory leak for the dns api.

2014-11-24

1, Fix the wrong length of wifi password compairison when configuring sta. pwd,64byte. ssid,32byte.

2, Fix dns problem, add a dns example to wiki.

2014-11-23

1, A temporary and dirty fix to heap drop issue:
to avoid reboot, a tcp-server will NOT accept a connection from client, if there is not enough memory.

2, file.list() now returns a table only. will not print result in serial directly.

2014-11-20

1, fix tmr.delay to support more than 2s delay, may cause bacon time out, lost connection to AP.

2, add tmr.wdclr to clear watchdog counter in chip, use in long time loop.

3, fix UDP part of net module.

4, add a timeout para to createServer(net.TCP, timeout).

2014-11-19

2, 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

now file operation support multiple read/write

for now file module only allowed one file opened

2014-11-5

delete log operation api from node module

add log module

modify wifi module api

modify node.key long_press and short_press default function

key is triged only when key is released

Thanks HEAVENS it's not in LUA itself. Good luck with manufacturer, I have trouble keeping a conversation going as it takes days... you might want to give others details so they can pester manufacturer to fix the problem - we're all dying to get stuck into this software.
