Question:Library Usage

[abhatikar]

Hi,

I am trying to use the library for using the https://www.waveshare.com/wiki/2.7inch_e-Paper_HAT.
I am using this with raspberry pi.I am successful in testing the demo code which is in python.
I am to get this working with nodejs for which I found this library.Could you please help on how to use this library ? Any sample code ? I am also new to nodejs...

thanks in advance..

I have also problems with this library.
I have a 2.9 e-Paper Display from Waveshare and it's connected to my RPI3

Paper HAT	wPi in script	Raspberry Pi GPIO Pin
VCC	3.3V	PIN 17
GND	GND	PIN 20
DIN		PIN 19
CLK		PIN 23
CS	10	PIN 24
DC	6	PIN 22
RST	0	PIN 11
LED	29	PIN 40
BUSY		PIN 18

index.js

var Epd = require('bindings')('epd');
var lcd = new Epd(0, 4, 6, 10, 0, 29); //initialize display
lcd.clear(); //clear all lcd
lcd.rect(50, 8, 50, 50); //draw rect
lcd.update(function() { //update all display
  console.log("LCD updated");
  lcd.clearPart(); //switch to partitial update mode
  lcd.rect(100, 100, 20, 20); //draw rect
  lcd.line(100, 100, 120, 120); //draw line in rect
  lcd.partUpdate(); //update only changed part of display
});

I get the error Segmentation fault

Any ideas @4ib3r @paranic?

i usually get segmentation error when i try to print something on top of something else or print something out of bounds.
watch closely what you print and in what position
