Hi Is it posebel to make somting to use a 16 x 2 LCD display, connectet to at MCP23017?

kubi57 commented 9 years ago

Hi,

yes, that can be done in lua. If you operate the LCD in 4-bit mode, an MCP23008 is also working.

Nice, has anyone don it in Lua code??

clixx-io commented 9 years ago

I've done it in python. Shouldn't take much to convert to LUA.

https://github.com/dvv/nodemcu-thingies/blob/master/lcd1602.lua but it's for I2C

JyskMaker commented 9 years ago

Hey dvv, MCP23017 is using i2c, its a 2 x 8 bit port extender, MCP23008 has only one.

No WIP, thus closing as per #719.
