Hello, I decided to try out Blockly for the first time and am using the same Parallax 4x20 LCD (Back Light + sound) I've used on many other SPIN projects.
Using 'Communicate-> Serial LCD', I have put in 'serial lcd initialize' with the proper pin#, and It will display proper text and variables via 'serial lcd print'...
But I cannot get any 'Serial LCD Command' to work.
I have tried every Command available on the list, but when I compile and look at the code, it says " // ERROR: LCD is not initialized! "
Please help, I cannot clear screen or even do a carriage return!
