https://github.com/board707/DMD_STM32/t ... /gfx_fonts and use it:
Code: Select all
#include "fonts/GlametrixLight12pt7b.h";
TFT_eSPI tft = TFT_eSPI();
char *utf8rus_P(const char *source)
{
char m[2] = { '0', '\0' };
int j = 0;
unsigned char n = 1;
strcpy(target, "");
while (1) {
n = pgm_read_byte(source); source++;
if (n >= 0xC0) {
switch (n) {
case 0xD0: {
n = pgm_read_byte(source); source++;
if (n == 0x81) { n = 0xA8; break; }
if (n >= 0x90 && n <= 0xBF) n = n + 0x30;
break;
}
case 0xD1: {
n = pgm_read_byte(source); source++;
if (n == 0x91) { n = 0xB8; break; }
if (n >= 0x80 && n <= 0x8F) n = n + 0x70;
break;
}
}
}
if (n == 0) break;
m[0] = n; strcat(target, m);
j++; if (j >= maxString) break;
}
return target;
}
loop ()
{
tft.setTextSize(1);
tft.setCursor(0, 20);
tft.setFreeFont(&GlametrixLight12pt7b);
tft.println(utf8rus_P("Привет"));
}
