Need help with Espruino Pico "LCD Hello World" Example - Getting scrambled text

The "Pico LCD Hello World" example (https://www.espruino.com/Pico+LCD+Hello+World) does not work as expected.

A) When I write something, text is shown mirrored (see picture "Hello-World-Mirrored"). Due to this I added 'g.setRotation(0,1);' to the code, directly after the 'g.clear();' .

B)When I try to increase the font in "Improving it...", I get scrambled text. It seems that the higher rows are cut off and displayed below the main text (see "Hello-World-Split" picture).

I get the same scrambled text on an SSD1306 I2C display (see "Hello-World-I2C" picture) using the I2C setup:
I2C1.setup({scl:B6,sda:B7}); // I2C Setup
var g= require("SSD1306").connect(I2C1, start);

Any idea what I may be doing wrong?

Thanks for any help.

Hi! Sorry about this - I think the issue is with bit-ordering (in Graphics.createArrayBuffer we changed the default value to be msb-first in new Espruino builds)

I've just updated the display driver modules for the LCD/OLED screen to explicitly ask for little endian, so if you try uploading again now it should work (without the need for mirroring in setRotation)

Hi Gordon,
Thank you very much for the update!
I will give it a try.

Short feedback: Yes, the update solved the problem.
Thanks!
