The touch screen handler was broken for the ESP8266 only. The library uses SPI write only configuration for ESP8266 so the SPI buffer can be recycled and it was left in write only mode. The library now switches back to read & write mode at the end of a transaction.

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.
