hi I'm working on the code of a video door phone and I'm trying to improve it. with 16 GB SD card the pictures that the camera takes can be seen on the LCD but when I connect the SD card to pc using a SD card adaptor it shows nothing is in the drive. with 2 Gb SD cards it only shows the last taken picture and when I click to see the next photo a black page appears. the core microcontroller is a M8051W named BIT1802 i used standard commands provided by spec sheets for MMC and SDSC . can someone give me a hint about what the problem might be ?
