Warning: invalid conversion from 'const char*' to 'word {aka unsigned int}' [-fpermissive]

I'm struggling a bit with this code

#include <UTFT.h>
#include <URTouch.h>
#include <Keyboard.h>

UTFT    myGLCD(CTE32_R2,38,39,40,41);
URTouch  myTouch( 6, 5, 4, 3, 2);

// Declare which fonts we will be using
// big font chars are 16x16
extern uint8_t BigFont[];

// 320px x 240x
// btn's are 90x60
int x,y;
int activeBtn = 0;
int btnX[] = {15, 115, 215, 15, 115, 215, 15, 115, 215,};
int btnY[] = {20, 20, 20, 90, 90, 90, 160, 160, 160};

// The the value of each index in btnLabel should match the value of the same index in btnVal
// ex: when the "Main" btn is pressed, we take it's index (0) and match it in btnVal[0], so the arduino sends "KEY_F13"
String btnLabel[] = {"Main","Over","Soldr","Laser","Mill","Routr","BRB","End","Empty"};
word btnVal[] = { "KEY_F13","KEY_F14","KEY_F15","KEY_F16","KEY_F17","KEY_F18","KEY_F19","KEY_F20","KEY_F21" };

When I verify it, these errors come up

And can not figure out how to fix it just tried trying to google, but do not think exactly it helps

word btnVal[] = { "KEY_F13","KEY_F14","KEY_F15","KEY_F16","KEY_F17","KEY_F18","KEY_F19","KEY_F20","KEY_F21" };

If this an array of strings why does it have a datatype of word ?

Did you perhaps mean

  char * btnVal[] = { "KEY_F13", "KEY_F14", "KEY_F15", "KEY_F16", "KEY_F17", "KEY_F18", "KEY_F19", "KEY_F20", "KEY_F21" };

Hi UKHeliBob

Unfortunately not, tried your suggestion but can see it has not got it all with, but under} there is a "^" and the same in the line with "yGLCD.print (" ", CENTER, 2);", which a "^" is placed below the last parentheses

[UKHeliBob]

Please post your revised sketch in a new post using code tags

#include <Keyboard.h>

word btnVal[] = { "KEY_F13","KEY_F14","KEY_F15","KEY_F16","KEY_F17","KEY_F18","KEY_F19","KEY_F20","KEY_F21" };

It looks like you intended to use the keycodes for Keyboard.write().

byte btnVal[9] = { KEY_F13, KEY_F14, KEY_F15,
 KEY_F16, KEY_F17, KEY_F18, 
 KEY_F19, KEY_F20, KEY_F21};
