The text orientation is not working correctly
Using 2.8 inch TFT Touch Shield v2.0 (seeedstudio)
Below is my code. Every time I clear the screen the text direction is getting reversed and self corrects itself randomly. Any suggestions, please.
#include <HID.h>
#include <SPI.h>
#include <stdint.h>
#include <TFTv2.h>
TextOrientation orientation = LANDSCAPE_UPSIDE_DOWN;
char volt[] = " mVs";
const float delayTime = 2000;
void setup() {
TFT_BL_ON; // turn on the background light
Tft.TFTinit(); // init TFT library
Tft.fillScreen(0, 240, 0, 320, WHITE);
Serial.begin(9600);
}
void loop() {
orientation = LANDSCAPE_UPSIDE_DOWN;
Serial.print(“Blue zone”);
clear_display();
draw_blue_zone(5, 42);
draw_voltage(2000);
delay(delayTime);
Serial.print(“Green zone”);
clear_display();
draw_green_zone(25, 82);
draw_voltage(4000);
delay(delayTime);
Serial.print(“Red zone”);
clear_display();
draw_red_zone(45, 122);
draw_voltage(6000);
delay(delayTime);
}
