Can I read two RX ports on two boards in parallel from one USB port

hi, before start have issue cleared. i did googled no satisfying result. two uno's doing 2 different tasks. one uno connected pc usb , sending data temperatures , force pc serial.print commands vb6 app. the second uno controlling steppermotor , needs receive serial data pc control steppermotor speed. i cant combine both tasks in 1 uno , not want 2 usb cables connected. so can connect in parallel 2 rx ports of both uno's data received uno usb connection send uno without usb connection? thanks thinking me. paco   if did connect them in parallel, plan ensure 1 board doesn't data belonging other board? paul Arduino Forum > Using Arduino > Project Guidance > Can I read two RX ports on two boards in parallel from one USB port arduino

erreur dans mon programme.

hello les codeurs. je fait appel à vous, car j'ai un projet 18 tourelles d'un destroyer de la seconde guerre mondiale à animer. faire bouger les moteurs pas à pas n'est pas un problème. mais là, ça dépasse mes modestes compétences. chaque tourelle à sa propre direction au repos et sa propre grandeur d'angle. et certains moteurs pourront avoir une ou plusieurs tourelles. ça c'est la partie invariable. ce que je compte faire c'est de me servir d'un arduino pour envoyer des ordres aux autre cartes qui auront un ou plusieurs moteurs pas à pas à gérer suivant l'angle de rotation initial. chaque moteur aurait une buté en début et fin de course, qui va servir lors de la phase d'initialisation. dans l'idéal, à partir de cette initialisation, les données de sa position seraient enregistrés, pour qu'en suite soient programmé plusieurs ordres de rotation (simulation d'un combat). je comptais programmer au moins 4 programmes pour le contrôl...

Problemi Mega con display

salve, chiedo aiuto in quanto non riesco venir fuori da un problema: ho un arduino mega con gran parte delle porte occupate da una shield aggiuntiva. mi rimangono libere le porte dal 31 al 51 e vorrei collegare il classico display 2x16 del kit arduino per fornire due informazioni. ho fissato il display su un circuito parte con potenziometro e resistenza variabile, testato il tutto su arduino uno con seguenti pin liquidcrystal lcd(12, 11, 5, 4, 3, 2); e funziona. adesso vorrei cambiare pin e collegarlo su quello che mi rimangono libere su arduino mega. ma ottengo soltanto quadratini lcd(39, 40, 41, 42, 433, 38). chiedo aiuto. grazie cross-posting vietato da regolamento. ti invitiamo presentarti (dicci quali conoscenze hai di elettronica e di programmazione) qui: presentazioni e leggere il regolamento se non lo hai già fatto: regolamento qui una serie di link utili, non inerenti al tuo problema: - qui una serie di schede xxxpighi per collegamenti elettronic...
