Enabling telnet on Netgear EVA8000 Digital Entertainer

The Netgear EVA8000 Digital Entertainer has a telnet daemon installed, but by default it is disabled. During bootup the startup script for the telnet daemon examines the contents of /etc/utelnetd.conf and starts the telnet daemon if the contents is set to “ENABLE 1”

Once telnet is enabled you can log into the system with the username “EVA8000” and the password “Netgear”.

There are two ways to do this depending on which firmware version you are running.

Nokia 3310 LCD Driver JAL PIC Library

[An old project I moved from my previous website, you can still find display modules using the PCD8544 controller, like this 5110 LCD Module] This JAL library includes functions for controlling the Nokia 3310 LCD (PCD8544 controller) and also a 5×7 font. Currently the table used only works on 16F, but should not take much … Continue reading Nokia 3310 LCD Driver JAL PIC Library

LM75 Temperature Sensor with 7 segment display output

[An old project I moved from my previous website] This is a test project built hastily on a solder less breadboard. It uses a LM75 to read the current temperature via I2C and displays the result on three 7 segment displays. It uses a PIC16F628 with an internal 4 Mhz clock. The program was created … Continue reading LM75 Temperature Sensor with 7 segment display output

PIC Binary Counter – A JAL Test

[An old project I moved from my previous website] This sample project uses a PIC16F628 and 8 LED’s to count in binary. Four switches are used to change the direction and speed of the counter. The program was created using JAL. The project is available for download here: [download id=”3″ format=”1″]
