This sketch reads the user setup information from the processor via the Serial Port
|
|
|
|
It is a support and diagnostic sketch for the TFT_eSPI library:
|
|
https://github.com/Bodmer/TFT_eSPI
|
|
|
|
The output is essentially a copy of the User_Setep configuration so can be used to
|
|
verify the correct settings are being picked up by the compiler.
|
|
|
|
If support is needed the output can be cut and pasted into an Arduino Forum post and
|
|
already includes the formatting [code]...[/code] markups.
