Equatorial mount used is a Fast Linear Reverse by Avalon Instruments, which mounts a stepper motor in celestial right ascension axis and a stepper motor in celestial declination one. We will talk about stepper motors (by Sanyo Denki), relative bipolar chip-drivers (L6208 by STMicroelectronics)and their embedded power circuitries (with a particular focus on working of full H-bridges), about digital\/analogical converters (AD7305 by Analog Devices) and firmware required to implement a proper microstepping drive by exploiting a simple 8-bit microcontroller by STMicroelectronics. Electronic board discussed here is a product designed and sold by LTEC srl and it has been matter of work for the author of this book during his internship at LTEC.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783639490084\"\u003e\u003ch3\u003eA simple hardware and firmware solution to implement a goto and sidereal tracking function\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783639490084","offer_id":39439412822109,"sku":"9783639490084","price":89.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6a472374-7431-471d-bb8d-6270a7c96ad1.jpg?v=1768974840","url":"https:\/\/shop.autorenwelt.de\/en\/products\/electronic-control-system-for-a-german-equatorial-telescopic-mount-a-simple-hardware-and-firmware-solution-to-implement-a-goto-and-sidereal-tracking-function-von-enrico-molinari","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
