That makes a lot more sense then. My problem had something to do with the i2c slave address. Either it was not reseting to 0x50, or address 0x50 got messed up somehow. Anyways by changing the slave address to 0x52, the communication works again and I'm up and running. Thanks for the fast reply ...

Manual Override Fails (GLK240128-25)

So I was doing pretty well with developing a dynamic menu for my device, but something stranged happened an hour ago. My LCD no longer read any I2C command coming from my processor, and the only thing I can think about is something shorted on the I2C LCD or the slave address changed somehow. Before ...

It was because I didn't delay after I set my exit condition high when a button was pressed. Thanks for the help.

New Question

I'm not sure how familiar you are with ARM7 processors, but I am having an issue making dynamic menus with highlighting. In the main.c file you need a while(1) loop that basically runs your commands. I'm trying to make states for my LCD so it will display certain content depending on where they are ...

Invert Text Color without making a new font?

I'm using a GLK240128-25 smart LCD and I was wondering if there is a command to invert the text color. This means if the default text color is black, is there a command that will make it white?

I'm trying to write a function that render out highlighted menus. I have a feeling a separate font file ...

We got our processor up and running and we're communicating over I2C. Sorry for asking so many questions but thanks for all your help.

I've never used VC++ before and when I tried to build those projects, they failed with errors I didn't really understand. I imagine that there are some missing include libraries or I need the full version of Visual C++. There isn't a simple way to do this in C, Java, or Python? Those are the ...

I downloaded a RS232 COM port program that allows me to send commands over the serial port, but it requires everything to be converted into HEX. I tried to google some ways to use C to communicate over the serial port but I couldn't find anything. Can anyone send me some source code, links, or give ...

Yes, the ARM7 will be programmed in C. So when you say to implement a sendchar and readchar function, I'm assuming there is an I2C library that I can use that will send data out of the Serial port on my computer?

Creating a virtual ARM7 Processor

I am working with the GLK240128-25 Graphic LCD for a school project and we have an ARM7 32 bit processor. I am in charge of programming the LCD and we are still trying to debug our board to get our processor working. I am wondering if anyone has a GUI or command line program that mimics the ...
