[BUG] I2C OLED not working on LPC1768 #14430

Closed istyszy closed 5 years ago

Hello,

I have found this topic on the bugs list and it is closed, but the problem still exists.

60039104-9ccacd80-96be-11e9-8df6-46cd2c73edd5

I have an i2c OLED display, with marlin 2.0 (2019-06-24) + SKR V1.3, i use hardware i2c from E1. When the board starts everything is OK, display works as it should, but after 40 sec or so, the display crashes. Did someone had this problem? I used the display with ramps+mega and never had any issues? I use u8glib_SH1160. (also tried U8GLIB_SSD1306 same result). My diy display: https://reprap.org/forum/read.php?13,499572,500608#msg-500608

I have tried all the solutions on https://github.com/MarlinFirmware/Marlin/issues/13257 even with a 3.3V regulator. the problem remains. display artifacts after some time.
