Reference to particular drivers in examples have been removed as multiple display drivers are now supported. Tabs replaced by spaces in header file by file editor. RPi TFT with write strobe SPI clock rate dropped to 20MHz (display cannot cope with new high rate siWriteBlock() function)

Tests string alignment
|
|
|
|
Normally strings are printed relative to the top left corner but this can be
|
|
changed with the setTextDatum() function. The library has #defines for:
|
|
|
|
TL_DATUM = Top left
|
|
TC_DATUM = Top centre
|
|
TR_DATUM = Top right
|
|
ML_DATUM = Middle left
|
|
MC_DATUM = Middle centre
|
|
MR_DATUM = Middle right
|
|
BL_DATUM = Bottom left
|
|
BC_DATUM = Bottom centre
|
|
BR_DATUM = Bottom right
|
|
|
|
|
|
Needs fonts 2, 4, 6, 7 and 8
|
|
|
|
Make sure all the display driver and pin comnenctions are correct by
|
|
editting the User_Setup.h file in the TFT_eSPI library folder.
