Hello everyone ;

I've been working on a project which requires an LCD display then I decided to get an oled in order to free some pins also to ease the PCB design
and I purchased an OLED code named EA W162-XBLW (ICEWHITE) of Electronic Assembly but I have a disturbing problem with the LCD .. After I power the circuit up I can perfectly display all the characters on whereever I want on the lcd but there is an incredible noise moving all around the LCD in a form of a pixel , So far I have tried using capacitors even those larger ones and even added the define LCD command and data line parameters with several tries ,, but no lock so far .. Here I share the code and a picture ... I hope any of you had such a weird problem in the past and solved it ...


The code is for 16F1827
Code:
#config
 __CONFIG _CONFIG1, _FOSC_INTOSC & _WDTE_OFF & _PWRTE_ON & _MCLRE_OFF & _CP_OFF & _CPD_OFF & _BOREN_OFF & _CLKOUTEN_OFF & _IESO_OFF & _FCMEN_OFF 
 __CONFIG _CONFIG2, _WRT_OFF & _PLLEN_OFF & _STVREN_OFF & _BORV_19 & _LVP_OFF
#ENDCONFIG
