and the 32x16 display
https://www.adafruit.com/product/420
The display works fine and I can fill the 5x2 character display with data from I2C sensors.
The problem I am having is refreshing the display (every second in my case) causes a slight flicker.
This is the basic code that causes the flicker every second in the loop.
Code: Select all
matrix.fillScreen(0);
matrix.setTextColor(matrix.Color333(brightness,0,0));
matrix.print("0");
//the above color and print are repeated 10 times
matrix.swapBuffers(false);
Also I want to send some data to another Adafruit Mega 328 via software serial. Which poirts are free after attaching the RGB Shield? I cannot seem to find a list of used ports.
Thanks for any ideas and info.
