What's the best way to do a lookup table in C? -


I am working on an embedded C project. I have an LCD display and 5x7 dot matrix for each character. I To display a specific character, you have to make a change in 5 bytes, which in turn are correlated with dots. So I need to create some sort of look-up table where I can pass in an ASCII character, and get an array of 5 bytes ... For example, call this function like this, < / P>

GetDisplayBytes ('A');

`An array like this should be returned ...

C [0] = 0x7E: C [1] = 0x90: C [2] = 0x90: c [3] = 0x90: c [4] = 0x7E

What would be the best way to do this in C?

I will create arrays for those ASCII blocks which you want to use. Information. Something like this: 

  uint8_t displayBytesLetters [] = {0x73, 0x90, 0x90, 0x90, 0x73, // 'A'. . . }; Uint8_t displayBytesDigits [] = {0x12, 0x15, 0x25, 0x58, 0x80, // '0'. . };

Then your GetDisplayBytes () is something like this: 

  uint8_t * GetDisplayBytes (char c) {if (isdigit (c) )) Returns and displaysbettes [5 * (C - '0')]; And if (Asperger (C)) Returns and displaysbettes [5 * (C - 'A')]; And return of return; }

Pass any function that returns the returned indicator: 

  Zero DoDisplay (uint8_t * displayBytes) {int i; (SendOutput (displayBytes [i]);}}
for I (i = 0; i & lt; 5; i ++)

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
