Compiler/DLPC300: Issue attempting to load a bitmap into the LightCrafter

Tool/software: TI C/C++ Compiler

I'm currently attempting to write a code in C/C++ to load a BMP into the DLP. The code compiles fine. I convert the bitmap into a vector and then copy and transfer, in a loop, segments of MAX size into the DLP. My issue is that at the second iteration, when the flag is 2 (neither, single, first nor last), the write() function fails and doesn't write all the positions (46336 out of 65542). Is there anything else I should in respect to the way I am treating the bitmap file?

I'm using the following code for parsing the bitmap -> stackoverflow.com/.../how-can-i-read-bmp-pixel-values-into-an-array

Hi Jmfras,

I'll need to look into this in a little more detail, I don't know off the top of my head how we handle the bitmap files in our code. You already have the source code for the GUI I believe and you can try to follow our bitmap parsing from there in the file called dlpc350_BMPParser.cpp

Best,
Paul

I must have missed that file as I 'm not recogninzing it's name. I'll look into it. Thank you very much!

Wait, I'm sorry - you're not using the Lightcrafter 4500 are you? You're using the Lightcrafter 3000? In that case you'd be looking for bmpparser.cpp, it should be in the GUI source code. If it doesn't have the clues you need, let me know.
