When I try to compile the Hello World example for Arduino Due (both Programming Port and Native USB), it yields this error:
{ARDUINO DIRECTORY}/libraries/Arduino_ST7735_Fast-master/Arduino_ST7735_Fast.cpp: In member function 'void Arduino_ST7735::writeSPI(uint8_t)': {ARDUINO DIRECTORY}/libraries/Arduino_ST7735_Fast-master/Arduino_ST7735_Fast.cpp:113:5: error: 'SPDR' was not declared in this scope SPDR = c; ^ {ARDUINO DIRECTORY}/libraries/Arduino_ST7735_Fast-master/Arduino_ST7735_Fast.cpp: In member function 'void Arduino_ST7735::init()': {ARDUINO DIRECTORY}/libraries/Arduino_ST7735_Fast-master/Arduino_ST7735_Fast.cpp:143:10: error: cannot convert 'RwReg* {aka volatile long unsigned int*}' to 'volatile uint8_t* {aka volatile unsigned char*}' in assignment dcPort = portOutputRegister(digitalPinToPort(dcPin)); ^ {ARDUINO DIRECTORY}/libraries/Arduino_ST7735_Fast-master/Arduino_ST7735_Fast.cpp:146:9: error: cannot convert 'RwReg* {aka volatile long unsigned int*}' to 'volatile uint8_t* {aka volatile unsigned char*}' in assignment csPort = portOutputRegister(digitalPinToPort(csPin));
Compiling for the Arduino Uno is fine, but for my current project, it requires the Due. Is there any way to fix this, or is it something different with the board? Thanks in advance!

First of all thanks for your fast library. Its really fast for smooth scrolling text. But I had an issue with smooth menu scrolling. When I pressed next or previous button the menu for next or previous menu item it made a little flickering which is unexpected for me. How can I solved it.
Here is my menu code:
` #include <Adafruit_GFX.h> // Core graphics library
#include <Adafruit_ST7735.h> // Hardware-specific library for ST7735
#include <SPI.h>
unsigned long startMillis, currentMillis;
// For the breakout board, you can use any 2 or 3 pins.
// These pins will also work for the 1.8" TFT shield.
#define TFT_CS 8
#define TFT_RST 7 // Or set to -1 and connect to Arduino RESET pin
#define TFT_DC 6
//-------------------Constants for row and column sizes-------------------
// For 1.44" and 1.8" TFT with ST7735 use:
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST);
//Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST);
//Adafruit_ST7735 tft = Adafruit_ST7735(8, 7, 10, 9, 6);

I were able to control my SD card and TFT LCD fine using the Adafruit libraries, but when I discovered that the Adafruit libraries were too slow for my tasks, I switched to Arduino_ST7735_Fast. And, when I run my code, the TFT LCD does not initialize properly and stays on a white screen, but the SD card can be read from and written to.

I would suggest you add commands to toggle the Chip Select of the LCD high or low so that I can control an SD card.

Hi, was trying a example ST7735_BigScroll.ino from the library, and it seem to crash after trying to render the scrolling text on nodemcu ESP8622 esp-12f with 1.8' (128x160) display.

I got RST line connected to 3.3v pin with a rezistor - doesnt make any difference if i connect it to a real pin

The serial output with Serial.setDebugOutput(true); if it helps with any troubleshooting

Any clues?

Hi, super library!

Will there be any support for the Arduino Zero samd21? I tried, but it failed to compile:
