Working on a small project that is outputting data to a ILI9341 display from Paul wired per the instructions. The data is updating pretty fast (reading it off CAN bus @500k). The screen does not seem to clear data on fields that are constantly changing. I am not sure how to address this in the code. I tried doing a simple screen fill, but it just makes the screen flicker.
I am pulling 3.3v for the display and CAN transceiver from the Teensy's 3.3v pin if that matters. Also I do have a 100ohm resistor on LED to VIN as well.
Project is a Teensy 3.2 reading data off a CAN bus using a WaveShare SN65HVD230 transceiver. Attached is the sketch I am using.
Here is a picture, notice the issue at the bottom for the TPS value
