Yes, it is similar because that's were I took it from :). The Arduino Mega 2560 has 10K pull up resistors on SDA and SCL data lines.
I've tried sending 0x50 as well without any luck. :( not sure what's going on here.

Hello, I'm trying to figure out how to get this thing going over I2C. I can't even clear the screen. I've tried with TTL using the Arduino Mega2560 board and it works well that way. By default the LCD is Address is 0x50 and when shifted right for 7-bits I get 0x28. Below is the code I've tried sendi...

Hello, I'm trying to create a menu for my LCD (LK204-25). I want to know how could it be possible for me to high light a line? The user will be using UP/DOWN key to "scroll" the menu. I can send data to the LCD, I'm just trying to figure out how to high light a line. that's all Thanks :jaw...

After days of playing around with the LCD and pic micro in serial I ithink your documentation needs some work. Some of your commands need before and after delays to get it working. The information might be somewhere but I can't find it.

Ok..so I went away from my code to try to figure this out... I wrote the following simple code... while(TRUE) { for(x=0;x<10000;x++); for(x=0;x<10000;x++); WriteUSART(0xFE); for(x=0;x<10000;x++); for(x=0;x<10000;x++); WriteUSART(0x47); for(x=0;x<10000;x++); for(x=0;x<10000;x++); WriteUSART(0x01); fo...

the clear command works just fine and the lcd is able to display text. I was able to fix the problem i was having before using the printf command. anyways there was an F being left of when the button was pressed and message displayed ONF. I added a space to ON and fixed that, not sure if that is the...

Hello all, I have written a code in C18 for PIC 18F452 to drive the LCD using the serial cable. I'm able to display a line which states if an LED is on/off. This works just fine, the problem is that at the end of the text in row 1 there is a box that doesn't go away. RB0 LED IS: OFF[] or RB0LED IS: ...

Hello all, I'm new to the pic world and I have already done some work with them like turning leds on and using the A/D converter, etc. Now I want to move to a serial LCD and use the PIC 16F877A to display data on it, like voltage, RPM, temperature and some other things. I want to use ASM and I have ...
