I am selecting a small display which can show 4 lines with 20 characters each. My sketch is working fine with a standard 4x20 backlit serial LCD but I wondered if it would be feasible a pocket version.
I got a 128x64 0,96" OLED which can do pretty well using 5x7 characters, actually it can do twice as many lines as needed, but I've read it can show pixel burn if some pixels remain a long time on. This is my case since the project is to show 8 values along its labels. Only the values will change, the labels will be subject to burn.
Then I got a Nokia 5110 LCD with 84x48 resolution, that translates to 6 lines of 14 chars at 5x7 font size.
I searched the internet for a 3x5 font for the 5110 LCD but only found some info for a Discovery board (https://stm32f4-discovery.net/pcd8544-nokia-33105110-lcd-stm32f429-discovery-library/) which is not useful for me.
Of course I could change the layout to take advantage of the lines surplus, but my idea was to use the lower half of display to show a live graphic of the readings. After all, those are graphic displays instead of the standard 4x20 char LCD.
A search within this forum got no hit. I don't intend to build such a library, it is way beyond my abilities. Am I looking for a unicorn? Any help will be greatly appreciated.
P.S.: Just for the records, the project is to get voltage, current, and temperature from a photovoltaic inverter thru a 433 MHz link and compute input and output power to show conversion efficiency.
