Help with Yourduino Serial LCD

YD Serial LCD


Hi folks,

Just received my Yourduino order and a little confused.  This is the Yourduino Serial LCD but does not match the info and photos on the Yourduino site.  I need help in getting this to work.  I have tried googling the flamingoEDA name and havn't found any matches in English sites.  It looks awfully like I2C to me whereas I want to use this as +5V, 0V and signal only.  After checking with a magnifying glass the socket to the right of the photo is labelled (top down)   -, +, R, T so I am assuming that I only need to wire the top three contacts?  Would love to know the required setting of the DIP switches (baud rate?) and use of the left hand connectors.


Any enlightenment woul be much appreciated.


TIA  PeteH

Ah yes my bad. You would think Terry would have some info for this. Have you emailed Yourduino Pete?

i don''t bring my feelings

they should document before selling something , clearly the shop is not ready yet and terry is spending too much time sunning him self on the beach in the Mediterranean   

I WISH!   That white stuff on the beach IS snow...  :-)

You mentioned the connector. It is a standard serial LCD. I would lay good odds that you will have to make all four connections. Power, ground, transmit, and receive. I can offer no help for the dip switches.

I found this: http://blog.flamingoeda.com/tag/eeprom/ (translated: http://translate.google.com/translate?sl=zh-CN&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&layout=2&eotf=1&u=http%3A%2F%2Fblog.flamingoeda.com%2Ftag%2Feeprom%2F)

I know it's not about the Serial LCD, but it has the same dip switches.
You could try it out.


Thanks Chuck,

I had already looked at that one.  It is a different board.  My concern is with the DIP switches - are these for I2C address or serial baud rate or both or none of the above?  Not knowing the defaults is the problem.



there is no info at all there

but im looking at my Parallax lcd and the switiches on it do

  1. Test
  2. 2,400
  3. 9,600
  4. 19,200

power it up and flip the first switch and there might be a test mesage printed to the lcd

sorry that's all i have for you at this point
