Updating - Gerfunky/TinyPixelMapper GitHub Wiki

If the unit is running already and has the formatted and populated File system (SPIFFS or SD) it is possible to update the unit over HTTP or Arduino OTA.

Arduino OTA

If your Arduino is setup correctly that you can compile and upload the Firmware the unit will show up in the Ports section of Arduino.

Platform IO

The PlatformIO.ini file is in the Extras folder of the SourceCode. If you use PlatformIO then you know what you need to do with it.

Update over commandline!

install arduino 1.8+
Follow installation instructions on https://github.com/espressif/arduino-esp32
enter the command below:
%userprofile%\documents\Arduino\hardware\espressif\esp32\tools\espota.exe -i IP-OF-ESP32 -p 8266 --auth= -f PATH-TO-BIN/NAME-of-BIN.bin

HTTP update

Another way is to upload the binary directly to a unit is if the HTTP server is enabled. Goto http://IP-ADDRESS/update select the binary and upload it.
