This month I bought the 2.4" TFT Color LCD,touch screen shield V1.2 for Arduino Mega( http://www.nuelectronics.com/estore/index.php?main_page=product_info&cPath=1&products_id=30) and have begun trying to run the pre-coded examples they provide on the company site. Everything works bar Bitmap example and the bitmap option in the menu example and I'm unsure why. I bought a new 8Gb SDHC card that reads fine on the PC and I added a 240x320 24bit bitmap called "tiger.bmp" to the ROOT directory as the example says (http://www.nuelectronics.com/download/projects/tft_examples_v1.0.pdf) and then I inserted the SD card into the SD card slot in the lcd shield. After selecting the "Bitmap" option in the menu example a message comes up saying "cannot mount SDcard" and in the bitmap example the screen stays black.
I'm a newbie when it comes to arduino and indeed electronics, (programming is more my area) so I don't know if I have missed something obvious. Have contacted the company to see if they have any ideas, but if anyone here happens to have any, I would be so grateful if you would share them! :)
