Raspberry Pi GPIO: Gambas + pigpio library

There are now a number of ways of controlling the Raspberry Pi general purpose I/O.

Libraries such as wiringPi and pigpio are written in the C programming language, but can also be used with other languages including Gambas.

I have covered wiringPi previously, and this short post is just a basic introduction to using the pigpio library with Gambas.

Raspberry Pi: headless, windowless file management

I have a number of Raspberry Pi music players that I need to add more tracks to from time to time.

As these players only boot to text (not a desktop) I can't use folder shares or VNC to access the file system.

Fortunately there is another very easy way. I can browse the file system by using secure shell file transfer protocol (sFTP).

Using Sockets with Gambas

Sockets are defined as communication end-points, and relate to a means of computer comms using IP addresses and ports.

Sockets are generally used to send data between two computers on a network, but may also be used to communicate between two programs on the same computer.

This post provides a simple introduction using the Gambas Client and Server Socket components.

Garmin eTrex: walking with GPX route files

We sometimes go for country walks using simple directions printed from the internet, usually accompanied by very simple maps.

These are OK as long as you don't take a wrong turn or stray off the correct path for some reason.

Although I cannot install topographical maps on my Garmin eTrex 10, I can use Route files.
