SparkFun SerLCD (LCD-14074) printing gibberish

Post by Joe0x7F » Sun Jan 13, 2019 11:45 pm

My "SparkFun 20x4 SerLCD (LCD-14074)" display is printing out just gibberish.

I have connected this SerLCD to a Red Board exactly like the hookup here (with the exact same logic level converter): ... ---initial

I have also compiled and uploaded the code listed here:

Serial UART: Example Code - Basic listed here: ... de---basic

It looks like to me that it is something like a baud rate mismatch problem except that when the SerLCD boots up, the LCD flashes that the baud rate is

Any ideas what to try next?
