[VILLO88]

Hi, i am trying to reproduce the controller V2 on breadboard with an arduino pro mini @3v,8mhz and the other components(128x64oled,buttons, max31856 etc..) , code is uploaded without problems but oled not working until i reduce screen height to 32 and temperature reading say "nan" all the time. The funny thing is, without changing anything in the wiring, if i try to load the test firmware for the max31856 and for the ssd1306 from the libraries examples sketch..both work without problems. The only way to get the oled working on 128x64 is to delete everything in the void loop under
// If switch 1 is pressed if (switchStatus == SWITCH_1) { the temperature reading still say nan..i really do not understand why..
