ST7565 LCD Programming Guidance

Hi Guys,

Total Arduino newbie here. I'm working on an experiment for my senior capstone design project. We have an Uno controlling some fuel injectors, with variable RPM and duty cycle. So two variables. We have the program working and controlling the fuel injectors properly. We want to display the RPM and duty cycle on an ST7565 LCD but are having trouble with the code. We have followed this tutorial: ST7565 LCD tutorial and have gotten the screen wired up and functioning properly. We can display characters and text, but we can't get a changing numerical variable to display on the screen. Any help would be much appreciated. Thanks!

Usually you do this by converting the number to a string first. There are sever options to do this. Most Arduino libs support the "print" member function, which automatically does this. Other options are sprintf or itoa.

You might also get more answers in other parts of the Arduino forum tree, because this question is more a software programming question that specific to a display.
