dnax / samsung_16lf01_vfd Goto Github PK

Found the problem, something I did myself 🐰 The 2 files .h and .cpp were present in the project folder which gave a conflict when verifying the code. Newby error, hope it helps someone in the future :)

I stumbled upon your github here and wanted to try and get my VFD going, not sure what is going on is this an error in the library?

I'm using an arduino uno r4

thanks :)

The Samsung 16LF01UA3, 16LF01UA4 and VFM161LSA1 all use the OKI MSC1937-01 VFD controller witch is a clone of the original Rockwell 10937 VFD controller.

Any VFD display that is based on the Rockwell 10937 VFD controller or one of its clones like the OKI MSC1937-01 or Micrel MIC10937 are compatible with this library.

Think of the Rockwell 10937 as the HD44780 for LCD displays, maybe you can rename the library to reference the name of the controller instead of a single module that is based on that controller.

The 9MS09SS1 display that also works uses a ML9209-xx VFD controller and a Nuvoton W78E052DPG microcontroller to translate the incompatible ML9209-xx protocol to the Rockwell 10937 protocol.

My display is fully functional with this library.

It is: VFM161LSA1

Many thanks for this lib!

Hello ,

i got my hand on an XBT-C7220 , they use 2 Rockwell 10937

Every thing look good except the charmap is strangely working :

When i ask for @abcdefghijk , i got @@CCDDGGHHKK

Even when i change the setCursor , when is ask for cursor pos 0,1,2,3,4,5,6,7 the text start at 0,1,1,4,4,5,5,8

i've tried to slow down the timing , i've checked with my scope that the reset is working correctly , eveything is fine .

it look like a problem with second lsb ;(

Do you have any idea ?

Thanks !

Is this supported? Samsung 16LF01UA4 with the controller OKI L9209-01
