luciann Posted July 13, 2019 Share Posted July 13, 2019 Salut, Exista o schema simpla prin care sa pot folosi un rotary encoder in asa fel incat atunci cand il rotesc spre dreapta sa faca cate un simplu contact la fiecare 'treapta' prin care trece, iar cand il rotesc spre stanga sa faca la fel, dar pe contacte diferite? am atasat un mic desen As evita arduino sau alte posibilitati care cer programare, daca exista o alta solutie relativ simpla. Multumesc frumos Link to comment
cimitavita Posted July 13, 2019 Share Posted July 13, 2019 exista. Cu un bistabil JK (7474) si inca cateva piese pe langa el. Exact aceeasi chestie o face si programul scris in microcontroler. Link to comment
luciann Posted July 13, 2019 Author Share Posted July 13, 2019 Ma poti indruma te rog catre o schema buna? Link to comment
Ticu Posted July 13, 2019 Share Posted July 13, 2019 (edited) Ce fel de rotary encoder folosesti? Niste exemple: https://www.sparkfun.com/products/15140 https://www.robotshop.com/en/cytron-simple-rotary-encoder-kit.html https://robu.in/product/incremental-optical-rotary-encoder-6002400-pulse-600-ppr/ Edited July 13, 2019 by Ticu Link to comment
luciann Posted July 13, 2019 Author Share Posted July 13, 2019 Facand research in continuare, am descoperit acest tip de switch: https://www.alps.com/prod/info/E/HTML/Switch/Rotary/SRBM/SRBM1L0800.html Cunoaste cineva ceva variante similare si mai low cost care s-ar putea gasi si prin Romania? Nu am nevoie de ceva pretentios si aparent, acest switch ar elimina necesitatea unui circuit pentru cazul meu. Link to comment
cimitavita Posted July 13, 2019 Share Posted July 13, 2019 (edited) prima schema are dezavantajul ca daca encoderul ramane cu un contact la masa, iesirea ramane activa. La pornire are acelasi dezavantaj. Astabilii 74123 elimina acest dezavantaj in schimb limiteaza viteza cu care se poate roti encoderul. Edited July 13, 2019 by cimitavita Link to comment
