Ok here is a brain twister

Have this program on an UNO

#include <Arduino.h>
#include <U8x8lib.h>

U8X8_SSD1306_128X64_NONAME_HW_I2C u8x8(/* reset=*/ U8X8_PIN_NONE); 	      

void setup(void)
{
  u8x8.begin();
  u8x8.setFont(u8x8_font_chroma48medium8_r);
  u8x8.drawString(0,0,"JOE");
 
}
void loop(){
}
`
`End Code``

I have a cheap logic analyzer and hooked it up to scl and sda and get a good run, but,
I can not find where it actually writes the data to the device.  It does 8 pages of 16 groups of each.
I can see where it turns the display on, but not the data "JOE".  Anyone have experience using pulseview on a SSD1306 oled?

BTW After clicking <code> to post code, how to you end it?

Thanks
