Hi Keith,
All the functions within Flowcode use Write mode only.
Therefore you must connect W/R pin on the LCD to 0V (Hence GND).
So its not a bug.

Hi Martin,

Thank you for your response.

I suspected Jorgen meant ground, but I took offense to the exclamation point. So, I wasn't sure if he was yelling at me to connect it to ground or if he was yelling some three-letter acronym at me.

Unfortunately, I, as well as others, have a need for software control of the R/W function of the controller in order to use the BF and and have the ability to read RAM. So, in the purest meaning of the word, it's not a "bug". Rather, it's a missing feature.

In any case, I believe it's either a bug or a function of the controller that should be made available.

Regards,
Keith

Hi Kieth

Sorry sorry, it was not my intention at all to be mad, yelling or the like this :D . I was just busy and I just saw your short question. I thought you knew what GND is, therefore, my short answer. Hope this is ok.

I am also very pleased to be able to get help here in the forum from all these kind people.

Martin thank´s for further support :wink:

Best regard Jorgen.

Hello,

If you use the LCD (Generic) component instead then this allows you to set the rows and columns and also allows the use of the R/W pin.

Indeed, it does, but that's a 2-line display. I need the R/W function for the 4-line display.

Hi,

Sorry I should have been clearer.

If you set the rows property to 4 and the columns property to 20 then that will match your display and provide the R/W pin functionality you require.
