Hi palanivel!

First, I don´t know your device you are driving your display with. But remember supply to the display is 3,3V and also 3,3V for the datapin, SPI.

Otherwise with 5V it will not work.

I change your testprogram. Of course first initialise , then set color background, then set color foreground, and then clear display. After that, you can write some text. But not let the your text "run" on full speed in the loop, otherwise I don´t think you see anything. Only write one time and wait until you want to write new text. Or put a delay in.

Look first at Lcd1 and then Lcd 2

I have played with these display, very nice.

Hi Jgu1,
After apply the 3.3V and my display is working. But the background and the letters are updating very slowly in LCD. Is it possible to make more fast update? Thanks for your help.

Hi

Glad it work. I used an Arduino mega. Yes it is a little slow when We compare with Arduino IDE. I don’t know the issue.

But anyway the speed it’s ok for me I am glad I can use It As a component in FLowcode..

Maybe MM team can explain you.

I am not sure if I am writing in correct group but I hope that someone from Matrix can help us. We are using PIC16F1513 IC in our design and now we have purchased Flowcode to program this chip, but now I was not able to find it in supported devices list. I remember that in the version Flowcode 5 and 6 there was workaround to add new chips. For Flowcode 8 I was not able to find such guidelines or example how to add this chip in supported list.

Hi jhonfilly,
Wecome to Matrix forums.
16F1513 is available.
If you cant see it as a target.
Them goto Help, Check for updates.
Change drop down from files in use to full database.
After files updated, you should see 16F1513
