Ive been searching for a while on how to erase the data before a new one enters. The data_values is a string variable. I tried to tft.print a null value but still the same. Any ideas on how or maybe someone did it already?
Serial.print("Voltage 1 : "); Serial.println(data_values[data]); tft.setCursor(((width_tft/10)-1)+5, 260); tft.print(data_values[data]);
Update : The link shows the output of my lcd shield. Also had a problem when the tft.fillRect is not updating its proper height size. Thou tested all of the drawings before completing the program
