Font draw speed and flicker test, draws all numbers 0-999 in each font
|
|
(0-99 in font 8)
|
|
Average time in milliseconds to draw a character is shown in red
|
|
A total of 2890 characters are drawn in each font (190 in font 8)
|
|
|
|
Needs fonts 2, 4, 6, 7 and 8
|
|
|
|
Make sure all the required fonts are loaded by editting the
|
|
User_Setup.h file in the TFT_eSPI library folder.
|
|
|
|
If using an UNO or Mega (ATmega328 or ATmega2560 processor) then for best
|
|
performance use the F_AS_T option found in the User_Setup.h file in the
|
|
TFT_eSPI library folder.
|
|
|
|
The library uses the hardware SPI pins only:
|
|
For UNO, Nano, Micro Pro ATmega328 based processors
|
|
MOSI = pin 11, SCK = pin 13
|
|
For Mega:
|
|
MOSI = pin 51, SCK = pin 52
|
|
|
|
The pins used for the TFT chip select (CS) and Data/command (DC) and Reset (RST)
|
|
signal lines to the TFT must also be defined in the library User_Setup.h file.
|
|
|
|
Sugested TFT connections for UNO and Atmega328 based boards
|
|
sclk 13 // Don't change, this is the hardware SPI SCLK line
|
|
mosi 11 // Don't change, this is the hardware SPI MOSI line
|
|
cs 10 // Chip select for TFT display
|
|
dc 9 // Data/command line
|
|
rst 7 // Reset, you could connect this to the Arduino reset pin
|
|
|
|
Suggested TFT connections for the MEGA and ATmega2560 based boards
|
|
sclk 52 // Don't change, this is the hardware SPI SCLK line
|
|
mosi 51 // Don't change, this is the hardware SPI MOSI line
|
|
cs 47 // TFT chip select line
|
|
dc 48 // TFT data/command line
|
|
rst 44 // you could alternatively connect this to the Arduino reset
