SoftwareSerial + Encoder rotative

Recommended Posts

Am pe un arduino uno, mai bine zis un ESR T3, libraria 8glib2 cu un ecran pe HW SPI, SoftwareSerial pentru RS485 si un buton cu push si encoder. 


eu de regula citeam encoder-ul cu vector compa cu variabile volatile si procesam in loop. numai ca acum SoftwareSerial deja folosește compa_vect pe toate ISR. 


Pinii 2 si 3 sunt luați de display.. ca de altfel si pinul zero deci fără hardware serial.. 


Ce posibilitate as mai avea sa citesc si encoder-ul? Eu ca soluție am modificat librăria SoftwareSerial, am transformat-o in alta clasa plus am adaugat  o clasa pentru encoder.. si merge dar.. nu sunt prea mulțumit ca fac citiri acolo cu digitalRead.. 


In afara de asta, ce soluție ar mai fi?

Daca nu mai ai disponibil nimic cu hardware ISR nu prea ai cum sa-l legi, din software nu vei putea procesa destul de rapid. Singura solutie e cu modul extern, fie iti faci singur cu un PIC12F un slave I2C care sa monitorizeze encoder-ul sau gasesti placute gata facute: https://www.ebay.com/itm/I2C-Encoder-Mini-connect-rotary-encoders-on-i2c-bus/174208386412?hash=item288fa1056c:g:CoQAAOSwPlFeXVTT
