I want to store list of items on SD card. Item will be selectable by up/down with select button on keypad and send to serial terminal for display.
For example, various vegetables list is stored in SD card. The user can retrieve the item one by one from SD card and see on LCD display using up/down buttons. And on pressing enter button on keypad, the selectable option is sent to Serial terminal by uart.
Please suggest what logic to use to store on SD card.
A text file on the SD card, with one line per item, would be a reasonable choice.
