|
||||
|
||||
hddledPi blinks a LED on any mass storage access. Not only on SD card access, but also on USB thumbdrive and hard drive activity. netledPi blinks a LED when there is activity on any network interface. Not only the built-in ethernet interface, but also on any other USB ethernet or WiFi interface.
|
||||
|
||||
netledPi and hddledPi make use of Gordon Henderson's wiringPi library - wiringpi.com - so you have to have that installed in order to build the programs.

netledPi and hddledPi make use of Gordon Henderson's wiringPi library - wiringpi.com - so you have to have that installed in order to build the programs. actledPi is a standalone, no special libraries are needed.
|

|

Building the programs is easy:
|
||||
gcc -Wall -O3 -o netledPi netledPi.c -lwiringPi
|
||||
gcc -Wall -O3 -o hddledPi hddledPi.c -lwiringPi
|
||||
gcc -Wall -O3 -o hddledPi hddledPi.c -lwiringPi
|
||||
gcc -Wall -O3 -o actledPi actledPi.c
|
||||
|
||||
hddledPi uses wiringPi pin 10 by default. It is BCM_GPIO 8, physical pin 24 on the Pi's P1 header.
|
||||
netledPi uses wiringPi pin 11 by default. It is BCM_GPIO 7, physical pin 25 on the Pi's P1 header.
|
||||
Note: These pins are also used for the SPI interface. If you have SPI add-ons connected, you'll have to use the -p option to change to another, unused pin.

Options for netledPi and hddledPi:
|
||||
-d, --detach Detach from terminal (become a daemon),
|
||||
-p, --pin=VALUE GPIO pin (using wiringPi numbering scheme) where LED is connected
|
||||
-r, --refresh=VALUE Refresh interval (default: 20 ms)
|
||||
|
||||
The programs need super-user privileges, so you have to start them with "sudo", e.g.

I have only tested them with Raspbian.
