How to clear line on Wifi Kit 32 display

#1

How can I clear only part of a line on the builtin display on the WifiKit 32?

I have GPS data that I want to display as it updates but I want it to overwrite the previous value without clearing other parts of the display.

The display will look similar to this:
ALT SPD SATS

###

LAT ##.######
LNG ##.######

The first line is the header and that stays on the display
The # parts are the GPS data which will be constantly updating

How can I do this ?
Thanks

After the full screen is cleared, the unchanged part can be overwrite with the same value. You can refer to the WiFi_LoRa_32Factorytest.

You don’t read well do you.

  1. I DO NOT WANT TO CLEAR THE ENTIRE DISPLAY
  2. PART OF THE DISPLAY TEXT WILL REMAIN ON
  3. ONLY WANT TO CLEAR PART OF THE DISPLAY

AGAIN, I ONLY WANT TO CLEAR PART OF THE DISPLAY. I DO NOT WANT TO CLEAR THE ENTIRE DISPLAY.

If you do not understand this please reply and I will try and explain again

I know your means, however, there is no partially cleared function.Maybe you can write 0 to the dot matrix that needs to be cleared.

Disappointed that the heltec library is so poorly designed. Maybe the designers should go back to Arduino school
