Nodejs EBOLED draw function is broken

[tylergibson]

@Jon-ICS Even the most basic draw call results in a segmentation fault in node.

var lcdObj = require('jsupm_i2clcd');
var oled = new lcdObj.EBOLED();
var tBuffer = new Uint8Array(1);
tBuffer[0] = 0xfe;
var error = oled.draw(tBuffer, 1);

There is no test or sample for the draw function to verify it actually works either. The rest of the functionality in EBOLED works - clear, setCursor, home and write. Any help or a working sample would be very appreciated if this function is indeed functional.

Found the issue. You cannot use a Javascript native Uint8Array to pass to draw. It must be a carray defined by swig. The following code works as expected.

var lcdObj = require('jsupm_i2clcd');
var oled = new lcdObj.EBOLED();
var tBuffer = new new lcdObj.uint8Array(1);
tBuffer.setitem(0, 0xfe);
var error = oled.draw(tBuffer, 1);
