Tags arm, linux, nodejs, tibbo

About the Application
You can expand the functionality of the prev app if you add a hardware button control. Pressing the button will also toggle the state of the GPIO line (LED, relay,...) which is reflected in the LED state displayed in the browser window.

What you need
Besides the hardware used in the prev app you will also need:
  • 1 x Tibbit #38 (push button)
  • 1 x Tibbit #00_3 (2 direct I/O Lines with 5V and Ground)

Quick jump to start NodeJS development on LTPS boards

Posted 01-18-2017 at 05:55 AM by Dmitry_Slepov

# Setup package repositories (if it's not done already)
smart channel --add a0 type=rpm-md name="LTPS all" baseurl=${RPMSBASE}/all/ -y
smart channel --add a1 type=rpm-md name="Tibbo LTPS general" baseurl=${RPMSBASE}/cortexa8hf_neon/ -y
smart channel --add

I have a 2008 HP 2133 Mininote PC, which is a small laptop machine. It has a 32-bit VIA C7-M Processor running at 1200 MHz. The memory is 2 GB and the single hard disk is 120 GB.

I originally purchased it with a vendor-installed SUSE distribution. I later installed Ubuntu 12.04 LTS. The machine is now at 14.04.5 LTS. I generally do weekly software updates as provided by Ubuntu.

Over the years, the machine gradually accumulated a lot of old Linux kernels, and it began...

One of the most common complaints on LQ Forums and other Linux forums is about wifi cards or adapters not being recognised in Linux.

Here are some typical lamented cries:

But it works perfectly in Windows. Why doesn’t it work in Linux?
