autoscroll() not working

[nalakawula]

I have lcd 16x2 with i2c backpack (PCF8574T). I run this code:

var five = require('johnny-five');
var chipio = require('chip-io');

var board = new five.Board({
  io: new chipio()
});

board.on('ready', function() {
        var lcd = new five.LCD({controller: "PCF8574T", address: 0x27, bus: 2, rows: 2, cols: 16});
        lcd.cursor(0, 0);
        lcd.autoscroll().print("Bloop").print("Bleep");
});

My lcd only display BloopBleep and a blinking cursor. Thanks

There are a number of issues emerging with I2C LCD devices and CHIP, I will post back here and on the other as soon as I learn more

Thank you

Hi @sumarouno,

Could you please also try this code with PR #19?

[nalakawula]

Yes sure. I have tried that code with PR #19. But still same. I got BleepBoop and blinking cursor. Thanks

Hi @sumarouno,

Could you also provide debug logs? DEBUG=chip-io node <file>.js

I'm interested to see what i2c methods are being called.

[nalakawula]

DEBUG=chip-io node .js

hi, @sandeepmistry . Nice to meet you again. I will try your suggestion but I'm at my office right now. I will give my report after I try at home. Thanks

I also try autoscroll() for my mega2560 and my lcd 1602 with i2c backpack. What i got is the same thing, "BleepBloop" with blinking cursor at the end. here my code for m mega:

var five = require('johnny-five');

var boards = new five.Boards([
{
    id: "mega",
    port: "/dev/ttyUSB3"
},
]);

boards.on('ready', function() {
    var lcd = new five.LCD({
        controller: "PCF8574T", 
        address: 0x27, 
        bus: 2, 
        rows: 2, 
        cols: 16
    });

        lcd.cursor(0, 0);
        lcd.autoscroll().print("Bloop").print("Bleep");
});

thank you

@sumarouno great idea to test with the Mega2560!

Since it doesn't seem specific to the CHIP + chip-io, I think we can close and move to the issue to the main Johnny-Five repo.
