What is GND?!

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

You're welcome.
I have moved topic from bugs to Feature requests.

Hi Kieth

Sorry sorry, it was not my intention at all to be mad, yelling or the like this . 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

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.

[keithh534]

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.

Got it!
