To be specific, it only prints characters from the upper 4 bit 0110 and 0111 rows, and the lower 4 bit rows where bit 4 and bit 5 are 1.How bizarre.

I got the arduino HelloWorld example working (but only with 4 pins, not 8-pin operation). Turns out I was getting pins 1-8 mixed up with pins 7-16.However, the sample code you provided in the other...
