Hello, I've been working with this 16x2 LCD and it worked just fine for about 3 weeks, but a week ago it started to show sometimes some weird characters and had to be reset to go back to normal functioning, and now it is happening more often. There are no inductive loads nearby. I am working with an arduino MEGA2560 and using the arduino library. I don't really think it has something to do with the code, when this happens the board keeps working as it should.
Any idea about why is this happening? I am no finding anything related in the dataseet, just suspecting static electricity damage.
Thanks in advance..
