Hello,
I have a 2,2" ILI9341 on a teensy 3.2 using ILI9341_t3 and snooze libraries (display connected standart wise, like on PJRC web site shown).
When I go to hibernate (snooze) it still draws current of app. 35mA.
Backlight was switched off before (via FET), also powerline of display was switched off before (via FET) and set display into sleep.
When I disconnect the display from the circuit and set to hibernate, I get the expected current below 1 mA.
I can't imagine whats the reason for the high current. Maybe some strange correlation between SPI and snooze?
Any ideas?
