DIY project is not from me thus credit goes to all who contributed to this (and other) projects:
(1) Arduino ST4 guiding DIY
https://github.com/k...re/arduino-st4/ and brief intro
ASCOM driver is in the first link.
INDI driver is here: https://github.com/tliff/indi_ardust4
Similar type of design (2) can be adapted to Raspberry Pi based projects using GPIO such as
iAstroHub3 http://www.cloudynig...trophotography/ and
The key point is since these are already using Raspberry Pi based system, and there are plenty of GPIO pins,
why not just take advantage of using them for ST4 guiding interface?
BTW a side note: ASCOM is just a common interface.
For example, the first DIY, you can find its ASCOM driver is called "Arduino ST4 Telescope driver". (See the first link, scroll down a little...)
There are many ASCOM mount interface drivers (and some of them are in the pulse guide style) http://ascom-standar...copeDrivers.htm
