Hi, below is some sample code , I cant seem to figure out why the first works ok but the second one doesn't display at all? i.e. it doesnt display the "ABCDEF " , what am i doing wrong?

include // Hardware-specific library

include "Free_Fonts.h" // Include the header file attached to this sketch

include

include

TFT_HX8357 tft = TFT_HX8357(); // Invoke custom library const int chipSelect = 53;

void setup(void) { tft.begin(); tft.setRotation(3); tft.fillScreen(TFT_BLACK); // Clear screen to navy background tft.setTextColor(TFT_WHITE, TFT_BLACK); Serial.begin(9600); }

void loop() { tft.setTextColor(TFT_WHITE, TFT_BLACK); tft.setTextDatum(TC_DATUM); tft.drawString("1234567890123456" , 5, 55, 6); tft.drawString("ABCDEF " , 5, 99, 6); delay(4000); }

The library font set was originally developed for the UNO which does not have enough memory for a complete font set. Font 6 therefore only contains numerical characters and a few others to support time and drawing floating point numbers: Thus the font only contains characters [space] 0 1 2 3 4 5 6 7 8 9 : - . a p m If you want to use other characters you will have to use one of the Free Fonts.
