I have a 16 X 2 display from Batron and got it to work no problem, apart from it being very small. So I got a 20 X 4 display by Batron and thought it would work no problem as the data sheets were virtually identical. Unfortunately the 20 X 4 display does not work, I thought it may have been a faulty…
