But, when I use \r\n\r\nw = u8g2.getStrWidth(infoText);  I get this error\r\n \r\nerror: no matching function for call to 'U8G2_SSD1306_128X64_NONAME_1_SW_I2C::getStrWidth(String&)'\r\n           w = u8g2.getStrWidth(infoText);\r\n\r\nI apologize for the simple question.  I found the u8g2 package after many false starts and really like what it provides.  But, as you can tell, I have a lot to learn yet.  Even if there are some features not implemented this is a really nice package that I will continue to use (and learn)."}}
