Filelisting with createMenu? #172
Description
Hi,
in my project i need to read the filenames from sd card and display it on an oled display. I can read the filenames from card and store it in an array. I can display the filenames with the ssd1306_createMenu function on the oled display. The problem is the number of menuItems. If i declare the structure as const char *fileItems[12]; i have 12 entrys for my filenames but if i have only 3 files on the sd card i have 9 empty entrys where i can scroll in the list (i hope you know what i mean). I changed the delaration to const char *fileItems[numFiles]; to have a variable value but there must be a constant, so i get the error from Compiler: "the value of variable "numFiles" (declared at line 253) cannot be used as a constant". How can i use the createMenu for listing files(without empty entrys) on the oled display?
Thank you.
