I have an Adafruit 716 RGB LCD shield installed on an Arduino Mega 2560. The display is working with basic functions (print(), setCursor, clear(), home(), ...) but the cursor(), noCursor(), blink(), noBlink() functions aren't working for me.
For example, the following code prints out "test" but without an underline. In my previous experience with other displays, setting the Cursor field in the display control underlines the characters.
- Code: Select all
Is this a known issue with the hardware or library, and is there a workaround available?
Thank you for your assistance!
(this is OT but this same 716 kit was shipped w/o the I2C pullup resistors and only had 5 of 6 PB switches. It also had a nice 2x15 female header that didn't seem to belong. Just an FYI!)
