indi_gpiost4

Fork https://github.com/zenmetsu/gpiost4 for rPi and wiringPi.

This is a dirty hack to use the minimal INDI (http://www.indilib.org/) driver for Kevin Ferrares Arduino based USB to ST-4 adapter (https://github.com/kevinferrare/arduino-st4). Basically, I cut out the middle-man and used the Pine64 GPIO libraries instead of making USB serial calls to a slave microcontroller.

The Pine64 and the RaspberryPI have truckloads of GPIO, no need to complicate matters by incorporating another device/battery-muncher.

License

This is based on the GPUSB driver and as such under the GPL2.

Features/Limitations

• No way to dynamically assign GPIO pins
• No Goto, just North, West, South, East
• Only works on Raspberry Pi

To Do

• Add support for dynamic GPIO assignment
• Find out how to allow clients such as KStars to dynamically load this driver as it doesn't show up in the list currently

Configuring

• GPIO pin assignments made in gpiost4driver.h
• Need to specify 4 pins total (RA+/- and DEC+/-)

Building

install wiringPi libs (*sudo dpkg -i wiringpi-latest.deb*)
cmake .
make

Installing

Just copy binary indi_gpiost4 to /usr/loca/bin/
and copy indi_gpiost4.xml to /usr/share/indi/
indi client (astroberry indiwebmanager, phd2, I think kstars also) show new Auxiliary driver: GPIO ST4

Running

indiserver ./indi_gpiost4
OR run from client
