Customer:
When I uploaded the Hello World code to Inkplate 4 TEMPERA, Arduino IDE needs 15.1 seconds to complete the code uploading. How can I speed this up? Also, how do I make letters bold?

Soldered Support:
For upload time: Arduino 2.0 has a better caching system than Arduino 1.8, so make sure you’re using that. If you compile the sketch once and then modify it and recompile and upload again, it should be faster. The initial compilation requires time, but subsequent compilations and uploads should be faster.
Check your ‘tools’ menu in Arduino for the upload speed setting. You can get it up to 921600.
To make letters bold, use a custom font. See the Inkplate docs at Inkplate 4TEMPERA - Printing Text | Soldered Documentation
