Hi there,

I just got a problem. I want to programm my arduino uno in atmel studio with the visualmicro plugin. My intense is to use a LCD with an I2C Serial Interface Module. There is an existing library available for the use of this module which I implemented in atmel studio.
https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads

But when I´m trying to upload the code on my arduino uno, it´s is not working correctly. The LCD is showing just a short part of the text then its just cleaning the display.

The code is available on the following link http://blog.mklec.com/how-to-use-iici2c-serial-interface-module-for-1602-lcd-display/

The code is

Code (c++):

/** * I2C/IIC LCD Serial Adapter Module Example * Tutorial by http://mklec.com * * Instructions at http://blog.mklec.com/how-to-use-iici2c-serial-interface-module-for-1602-lcd-display * * This uses the Liquid Crystal library from https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads GNU General Public License, version 3 (GPL-3.0) * Pin Connections: *      SCL = A5 *      SDA = A4 *      VCC = 5V *      GND = GND */ #include <Wire.h> #include <LCD.h> #include <LiquidCrystal_I2C.h> LiquidCrystal_I2C      lcd(0x27,2,1,0,4,5,6,7); // 0x27 is the I2C bus address for an unmodified module void setup() {     lcd.setBacklightPin(3,POSITIVE);     lcd.setBacklight(HIGH); // NOTE: You can turn the backlight off by setting it to LOW instead of HIGH     lcd.begin(16, 2);     lcd.clear(); } void loop() {     lcd.setCursor(0,0);     lcd.print("http://mklec.com");     lcd.setCursor(0,1);     lcd.print("I2C Module Demo");     delay(1000); }

I don´t know where the problem is. Does someone has an advice on this problem?

Hi,

Do you get the same problem in the arduino ide?

Thanks

No in the Arduino IDE it is working well. But I had to replace the arduino LCD-Library with the provided LCD-library for the l2c module. Could this cause the problem ?

Please switch on "vMicro>Compiler>show build properties" and also the "Verbose" option.

Probably some confusion resolving the library. Try removing the LCD library then restarting the ide

Then click Build>Clean then Build and post the output as .txt file or email to info[at]visualmicro.com with link to this post.

Thx for the advise. But I think I found the problem. The "vMicro->Debugger>Automatic Debug" was enabled. I just disabled this option then it worked fine. I also think was just in the debug mode all the time  ::)
