Hello every body.
I use a 192x64 GLCD with four KS0108 chip and u8g2 library .
the pins of my GLCD is ;
1-8 DB7 - DB0
10 R/W —> Set to GND according to the library
11 RS (dc)
12 Vo —> cnnect via 10 Kohm to the pin 17 Vout
I upload U8g2Logo example from library and see picture 1.
I setup the glcd according below :
U8G2_KS0108_ERM19264_1 u8g2(U8G2_R0, 6, 7, 8, 9, 10, 11, 12, 13, /*enable=*/ 5, /*dc=*/ 3, /*cs0=*/ A1, /*cs1=*/ A0, /*cs2=*/ U8X8_PIN_NONE, /* reset=*/ U8X8_PIN_NONE); // Set R/W to low!
because my GLCD has no CS2 pin , i use “U8X8_PIN_NONE” for CS2.
when i change the code , and want to draw a box to fill all pixel i see picture 2. that seem one of the chips , not select to receive the code (Excuse me for my bad English writing ). How i fix it.
thanks for your advise .
