I get an error Error: Identifier "Font8x12" is undefined in "main.cpp", Line: 20, Col: 21
I get an error Error: Identifier "Font8x12" is undefined in "main.cpp", Line: 20, Col: 21 if I use the below code.
TFTLCD
#include "mbed.h" // include the library, this will also pull in the header for the provided fonts #include "ssd1289.h" // prepare the data bus for writing commands and pixel data BusOut dataBus( p30, p29, p28, p27, p26, p25, p24, p23, p22, p21, p20, p19, p18, p17, p16, p15 ); // 16 pins // create the lcd instance SSD1289_LCD lcd( p14, p13, p12, p11, &dataBus ); // control pins and data bus int main() { // initialize display - place it in standard portrait mode and set background to black and // foreground to white color. lcd.Initialize(); // set current font to the smallest 8x12 pixels font. lcd.SetFont( Font8x12 ); // print something on the screen lcd.Print( "Hello, World!", CENTER, 25 ); // align text to center horizontally and use starndard colors while ( 1 ) { } }
If I use lcd.SetFont( &TerminusFont ); it compiles, is that correct?

Looking at the library history, it looks like there used to be a file called fonts.h which defined Font8x12. However, in January 2013, he replaced the old fonts with the new Terminus fonts. So presumably, you will need to do an #include of the terminus.h file, and then refer to one of the Terminus fonts that are included, they are called TerminusFont and TerminusBigFont.
