ST7565 font size

Hi
How to change the font size in this code?

/*
  1. "BL" (backlight) is digital H level control input, NOT direct driving of LED cathode (or anode). BL is a base pin of an NPN key with serial resistor 2k2, and need relatively big driving current (compared to NMOS keys)
  2. column address starts from 0, not ftom 4 (like in most 128 colum displays)
  3.  "DC" pin is "A0" controller pin,
  SCL and SDA
  #define BACKLIGHT_LED 4

  // pin 9 - Serial data out (SID)               , SDA = PB7
  // pin 8 - Serial clock out (SCLK)             , SCL = PB6
  // pin 7 - Data/Command select (RS or A0)      , DC
  // pin 6 - LCD reset (RST)                     , RST
  // pin 5 - LCD chip select (CS)                , CS

  ST7565 glcd(PB7, PB6, 7, 6, 5);
  //ST7565 glcd(SDA, SCL, DC, RST, CS5);
  ST7565 glcd(9, 8, 7, 6, 5);

#include "ST7565.h"

//ST7565 glcd(9, 8, 7, 6, 5);
//ST7565 glcd(40, 38, 36, 34, 32);

ST7565 glcd(PB7, PB6, PB5, PB4, PB3);
void setup()   {

  // initialize and set the contrast to 0x18
  glcd.begin(0);// glcd.begin(10);, glcd.begin(brightness);
  // glcd.clear();
  delay(10);

  // draw a string at location (0,0)
  // glcd.drawstring(0, 1, "TEST  23434 45675");
  //  glcd.display();

}

void loop()
{
  glcd.clear();
  glcd.drawstring(0, 1, "TEST  23434 45675");
  glcd.display();
}

You would have to use another library that supports the ST7565.

The one you are using has a fixed 5x7 defined font

Thanks. I am using stn32f103 which is ARM not AVR.
I cleaned up the code.


#include "ST7565.h"
ST7565 glcd(PB7, PB6, PB5, PB4, PB3);
void setup()   {
 glcd.begin(0);// glcd.begin(10);, glcd.begin(brightness);
 delay(10);
}
void loop()
{
  glcd.clear();
  glcd.drawstring(0, 1, "TEST  23434 45675");
  glcd.display();
}t
