eInk screen is causing reboot on RaspberryPi0W

QUESTION

eInk screen is causing reboot on RaspberryPi0W

Asked 2019-Feb-04 at 09:36

I'm trying to get to work a raspberry pi 0 W and a pervasive display eink screen together.

But, every time when the screen refresh, it reboots the pi 0. Software works great on a RPi3 but not on Rpi0w with Raspbian Lite.

Here is the soft : EpaperDisplay

Here is the screen : Screen

There is no log in /var/log/messages, neither in /var/log/syslog. Every time it reboots, it's erasing history, logs ...

If this was a software issue, you would probably see something in the logs (or you'd at least see a kernel panic message on the console in the HDMI output if you have a screen connected there).

If you have nothing in the HDMI screen when the pi crashes, I'd suspect that the display is using more power than your power supply can provide. Try with a PSU with a higher ampere rating.

If a better power supply does not help, it can be that the display sucks too much 3.3v from the raspberry pi than the zero can provide. In that case you should try feeding the display via a separate 3.3v regulator.

Vulnerabilities

No vulnerabilities reported

Install ePaperDisplay

You can download it from GitHub.
You can use ePaperDisplay like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.

Support

The original e-paper display does not have WiFi support. I added an ESP8266 module to it as a TCP-serial relay and it works pretty well. epd_connect() will try TCP connection first, else falls back to serial port. All function calls are the same for TCP or serial connection, except I have not implemented read-reply via TCP. i.e. no VERBOSE mode for TCP/IP connection. The baud rate should not be changed while connected via TCP/IP, as the WiFi module defaults to 115200 bps which does not change with the e-paper display. In wifi-relay folder you will find the firmware and scripts to be deployed onto the ESP8266 WiFi module.
