Hello,
is it normal that an OLED I2C display (SSD1305 controller) goes off when the Arduino is asleep (power down mode in Atmega328)?
The display just has Vcc, Ground, I2C, Reset connections.
I checked if the Reset connected to a digital pin was changing level, but that is not the case, it always stays high. Just when I initialize the display it goes low for few milliseconds.
A 7 segment LED I2C display that is on the same I2C bus stays on and keep displaying the last data it got.
Has anybody experienced the same?
Thanks for any suggestion.
Sincerely
I found out the problem was the MCU running low on RAM , about 250 bytes free of 2000 and that was causing the display not to behave correctly.
