hello,

Thank you bigcheese1960,

Now, I need only w5100 ethernet shild, as far as I understand. I have arduino uno. but how can check all data in arduino from internet, and how can I send ?
what is your advise, which program should I use?

How can I do OPCSerial

arduino is running and even with arduino ide program, lcd keypad shield is working. in flowcode, arduino is work, but in flowcode ı could not do anything about lcd, not work lcd. ı can do control back light but write problem.

Why I could not write. what can be my wrong.

viewtopic.php?f=54&t=16706

above is my old topic, ı tried everything but unsuccessful

I want to see all inputs and outputs via internet in other city. and I want to set all outpust and variable.

How can I do, what I need, scada and web interface program. I dont know anything about web communication programs with arduino.

hello,

I want to learn this. what I need?
Arduino uno, ethernet shild, and what? and which ethernet shild?
I want to learn urgently, help please. what I buy and need.

hello,

I repaired LCD now working with arduino ide program.
for flowcode, I am waiting your help

Hello, could you write anything to LCD shield? I cannot write

do you advise I2C and LCD ?

ok ok I understand I can not make this panel.
which panel must I use with flowcode?

I connected RW to D0. in properties and hardware I set RW to D0. in program I set D0 =0 and D0=1 but not work.

hello,

I found LCD Adafruit OLED. it look like my LCD. but in properties, rw_pin is problem. because rw_pin connect directly to ground (-). in flowcode, I have to select any pin for rw_pin. I could not select ground or minus. so not change any thing.
Thank you your help.

HELLO,

This is liquid crystal library,

what can be problem? LCD panel work, because in arduino original program, I load program to arduino LCD work. but I could not work with Flowcode 6 and 5. I tried every thing. I could not solve.

HELLO,

I tried your said, I used LCD Generic, but not changed anything.

I tested in proteus isis, it is working. I inserted picture in attached. but ı coult not work in real. I made every thing same but not work...

hello LCD pin number arduino uno pin numbers D4 D4 D5 D5 D6 D6 D7 D7 D8 D8 D9 D9 D10 D10 VSS GND VDD 5V I tried this even with arduino nano but result same, LCD not work. I changed arduino pins in program and hardware but result same. LCD not work with flowcode. ı could not solve.

HELLO,

My flowcode licence is student version. is lcd working possible ? My program work in Proteus isis, and flowcode 6 simulation. but in real it is not work. ı will be crazy, ı dont understand.
help me please... urgently

hello, LCD work arduino program in attached. but it could not be worked flowcode 6. yesterday I downloaded flowcode 5, ı think maybe flowcode 6 problem but it was not working. ı dont understand. ı think my problem can be pin description. ı looked, everything like normal.

I am waiting your help

hello,

Thank you for your help. I tried but same problem it is not work. in simulation mode it is working, but in real not work.

Hello my friens, I have problem about LCD writing. I have arduino uno and LCD Keypad Shield. when I write program arduino original program Writing is succesfull. but I try to write with Flowcode 6, I could not writing anything. when simulation mode in flowcode, I see program is working and LCD panel...
