I am doing some work with a LCD graphic display and a microcontroller. I have defined the alphabet in a series of constant char arrays that tell me what bits to turn on or off to display that character - ie. for '0' (0x30) const char CS22PT_0x30[122] ={18,40, 0x00,0x00,0x00,0x00,x00,0x10, etc......... } The first two numbers are the x and y size of the character. I call this array by char far *name name = &CS22PT_0x30; Display_Graphic(name); And this works. As long as I know ahead of time what the name of the const char array I am calling is. So the next step was to take a char array containing the string I want to display and determine which const char array to call on the fly rather than hard coding it in. What I have so far is an array predfined as char text_1[] = {"Night's Beautiful Daughter"}; I set a pointer to the array char *t_to_d; t_to_d = &text_1[0]; call a function that uses that pointer and the name of the font to use write_text(t_to_d,font_22) font_22 was previously defined as char font_22[]={"CS22PT"}; the write_text fucntion then converts (starting with the first character of text_1[0]) into a hex value that is cat onto the font name. ie Since the first character in text_1 is 'N' which is 0x4e in hex, I get an array that contains CS22PT_0x4e FINALLY I can ask the question!! How do I use the string "CS22PT_0x4e" in the array to point to the const char CS22PT_0x4e so I can get the data out of const char CS22PT_0x4e? Thanks, David
Hi, Which language are u using??/ In case you are using C++ you canuse STL map containers map<unsigned int, char *> mymap. Here key (unsigned int) would be hex representation of character...n your example - 0x4e
