Since Jan. 2017, we lunched a new version of universal adapter, on this new adapter, it will auto detect the GLCD controller: ST7920 or KS0108, no setup needed any more, the following information only applicable for older version of adapter.

 

1) For ST7920 LCD controller:

  • Verify and compare the pinout on adapter and LCD panel, they should be same on order (refer to the picture bellow);
  • Pull up PSB pin (usually pin# 15) to VCC to let the LCD panel work at parallel mode;
  • Connect the adapter with the LCD panel, adjust the contrast pot, power up the adapter, you should see the welcome screen displayed.

 

2) For KS0108 controller: 

  • Verify and compare the pinout on adapter and LCD panel, they should be same on order (refer to the picture bellow);
  • Shorting the 2 KS0108 jumper: 7 on the picture;
  • In most case you need add a 10K contrast pot by yourself, 2 fixed legs connect to GND(pin #1) and Vout(pin #18), the adjustable leg connet to Vo(pin #3);
  • Connect the adapter with the LCD panel, power up the adapter, send chip configuration command (refer to above table) to adapter;
  • Adjust the contrast pot, you should see the welcome screen displayed, if not, you probably need to try other value (1,3,4) in chip configuration command.

 

3) For ST7565 controller:

 

NOTE: There are vary of ST7565 LCD panels on market, and the pin out are vary from one module to others, this adapter only support SPI mode on the LCD panel, you usually need to connect pins on this adapter with LCD panel corresponding.

  • Connect the pins on the adapter with LCD panel corresponding;

  • You can use the set contrast command to adjust the contrast (ST7565 support software contrast adjustment).
