A 16x2 display needs to show on line 1 a floating voltage value (between 0,00 and 99,99) and after that a integer temperature 1 value (0 to 999). On line 2 the same but now with first a current (amperage) and then another temperature 2 value. What happens is that when voltage changes between 9,99 and 10,00 the temperature 1 value also shifts position. Same on line 2.
How do I give both temperature readings a fixed position independent of the value of either voltage or current?
