I have a ADM1602U ( serial enabled) that I am trying to use to print real-time counts using the SparkSoftLCD library but each time I do I get a strobing number with CPM. There seems to way to update the number without making the number disappear each second.
Is there any example of printing values to the screen continuously?
We’re not familiar with that library, you might try filing an issue on it’s Github page to see if the author has any advice.
One thing we’ve seen with these displays is the rate that you update information can sometimes cause a flicker on the display. If that’s happening, you might speed up or slow down the rate you’re updating the numbers on the display to see if that resolves the issue.
