Part Number: MSP430F5659
Hi
I have been using the Grlib functions in a product that has a 480x272 color graphics display using 16 bit color(565) format for 24 bit color.
Two Questions;
1- When I rewrite a string repeatedly in the same location using either "Graphics_drawString" function or "Graphics_drawStringCentered" I get residue of the previous string still in the screen. In other words, it doesn't completely rewrite over the existing array of the font I'm using. I'm using various fonts from the library such as g_sFontCmss20b, etc. How do I clean that up? Is there a full dot matrix character that I should write first to clear the array before writing the new string or is there a better way?
2- I'm using the Graphics_drawButton function for touch screen selection buttons. It's kind of boring looking and I'd like to use a button that has a 3D look. I assume the Draw _image Button function is for that. Are there any image buttons available that I can download. I saw one TI picture of a display showing a red raised button with the string 'done' on it somewhere, but I could not find any images that I can download and use? Also, I would need to scale them of course to the button size I need.
Please help,
Thanks
Jerry
