I'm having the same issue. I'm tried the same steps mentioned above and have all 4 or my pins poking through.
Although I'm a noob to electronics I can't seem to get mine to display. I've tried various configurations and still no text. I can get the backlight to come on but that is about it.
I'm backer #1239
I've also included a dump of the g = require("PCD8544") variable.
{
"buffer": new ArrayBuffer(504),
"flip": function () {digitalWrite(c,0);b.write([64,128],d);digitalWrite(c,1);b.write(this.buffer,d)},
"setContrast": function (a) {digitalWrite(c,0);b.write([33,128|E.clip(127*a,0,127),32,12],d)}
}
How can I fix this? Also are there any commands that I can execute that will give me diagnostics of the board to tell me if there are any issues.
