Hi Tom,

No problem, I've only connected the USB to it at present!

Thanks

Hi Tom/Everyone,

Just completed my homemade AstroEq, its the Mega based version, and I've added the standalone parts, also put together a small switch box to test the ST4 controls, its working nicely with a test Arduino program to my EQ5, even have it free running at ~ sidereal rate. I can also do some basic control it from lin_guider, so the hardware all looks good.

I do have 3 questions though :)
1. If I get the v7.5 source from github is there any instructions on how to compile/upload the code (I'm running under Linux BTW)?
2. If I upload this code (or the normal master branch code) to my Arduino Mega, can I roll back to my test Arduino code if necessary? (i.e. Does AstroEQ affect the Arduino bootloader?).
3. In the new code there may be a small issue I think. Where the test is made for standalone mode, it tests both new pins, but surely it should test only the standalonePin[0] (mode) in line 440 of AstroEQ.cpp? Otherwise if the standalone mode is off and the standalonePin[1] (speed) switch is set low, the code will not find a valid clause in the if...else structure?

Sorry for all the questions, and thanks for the excellent project!

Hi Phil,

The strict answer is yes, there should be two sets and they should be located physically close to each of the drivers to isolate their sudden current requirements from the rest of the circuitry.

Would you get away with only 1 set , probably... :)
