Hi Peter; Working on my encoder, I have a 5 to 1 signal attenuation according the the halscope. I'm useing ATS-667's to sense the bull gear that turns with the spindle. But the go-2, aka goop holding them in their pockets of a curved piece of alu was rotted by the 0w20 oil I use in the bronze bearinged spindle running out the rear of the bearing and migrating or being thrown up to the bracket holding the ATS-667's.
Putting it back together with jb-fastweld this time hoping it will withstand the inevitable oil, I hooked the halscope to hm2-encoder-0 a, b and index, and set it up to check quadrature. quadrature is way off, but what concerns me in that these ATS-667's are running on 5 volts, normally switch rail to rail. But at the hm2-encoder-0 a b or Index, I am seeing a decent square wave, but its only 1 volt p-p. For all three ATS-667's. Since that is the input, shouldn't I see pretty close to the same rail to rail coming out of the ATS-667's? Orrrr, does the halscope need a different gain calibration when its running on an rpi4?
