nodemcu + sparkfun micro oled display issue
« on: October 23, 2016, 08:45:04 am »
I'm having some problem with the NodeMCU and the micro oled display breakout board from sparkfun,
everything works but i noticed that i does not display any text at all, i tried this with the sample code that they provide.
Another problem is that in the demo code this part
Code: [Select]
void pixelExample()
  printTitle("Pixels", 1);
  for (int i=0; i<512; i++)
    oled.pixel(random(oled.getLCDWidth()), random(oled.getLCDHeight()));

causes the nodeMCU to display this message on the serial port
ets Jan  8 2013,rst cause:2, boot mode:(3,2)

load 0x4010f000, len 1384, room 16
tail 8
chksum 0x2d
csum 0x2d

I'm using arduino IDE to write the code for nodeMCU, and the NodeMCU and the oled display is connected via SPI.
