/*

|
||||||
This sketch has been written to test the Processing screenshot client.
|
|
||||||
|
|
||||||
It has been created to work with the TFT_eSPI library here:
|
|
||||||
https://github.com/Bodmer/TFT_eSPI
|
|
||||||
|
|
||||||
It sends screenshots to a PC running a Processing client sketch.
|
|
||||||
|
|
||||||
The Processing IDE that will run the client sketch can be downloaded
|
|
||||||
here: https://processing.org/
|
|
||||||
|
|
||||||
The Processing sketch needed is contained within a tab attached to this
|
|
||||||
Arduino sketch. Cut and copy that tab into the Processing IDE and run.
|
|
||||||
|
|
||||||
This sketch uses the GLCD, 2, 4, 6 fonts only.
|
|
||||||
|
|
||||||
Make sure all the display driver and pin comnenctions are correct by
|
|
||||||
editting the User_Setup.h file in the TFT_eSPI library folder.
|
|
||||||
|
|
||||||
Maximum recommended SPI clock rate is 27MHz when reading pixels, 40MHz
|
|
||||||
seems to be OK with ILI9341 displays but this is above the manufacturers
|
|
||||||
specifed maximum clock rate.
|
|
||||||
