In Melzi ATmega1284p is in TQFP package. I check pins with atmega datasheet, melzi documentation and with multimeter and its correct. Pin 29 is Aref Pin 28 is Gnd Pin 27 is Vccby ZaQ_1 - Controllers
Does someone run it on Melzi board? I follow all instructions and oled works but encoder not. In theory Melzi is compatible with Sanguinololu but in Melzi ADC inputs are on pins 36,35,34 and 33. So i changed this part of code in pins_SANGUINOLOLU_11.h #if defined(SSD1306_OLED_I2C_CONTROLLER) || defined(SH1106_OLED_I2C_CONTROLLER) #define LCD_SDSS -1 #define BTN_EN1 36 // A1 - rotarby ZaQ_1 - Controllers
