I have this code for monitoring the levels of batteries and a display that shows voltages, including total voltage, lowest and highest cell which has some issues.
When booted the tft display will show a lovely logo from an SD card as instructed, it will then draw all the lines and numbers, including the bar graph for total voltage. After about 2 seconds of running, the digits will start to glitch and write over one another or be upside down etc…
Any idea what is causing this?
Also, not anymore, but a while ago the display would sometimes not work and show a greyish snowy background with lines horizontally across it and not display anything, the serial monitor would also get stuck, any ideas would be nice but this is secondary as it seems to have stopped?
Thanks in advance!
