Arduino Nano

[fane]

schema pe care am luato de pe net e altfel pe nano nu am D0 siD1 RD WR RS si CS afisajul e la fel am doua afisaje diferenta intre ele e doar ca unul nu are pe spate circuitul notat cu U1 in poza ta

Foloseste semnele de punctuatie!

Scuze pentru viteza de scriere. Dar problema tot ramine in picioare

Pai nici nu o sa gasesti aceste adnotari in pinout-ul Arduino.

Pinii cu pricina ii asignezi in sketch cum iti este tie mai convenabil

[fane]

nu stiu ce sa mai fac.Am luat de pe net mai multe sketch-uri si cred ca am probleme cu programul majoritatea nu mi le compileaza,

imi da numai erori? Unele sint pntru arduino uno am setat placa ca fiind uno sinici asa nu merg?

si compileaza-l.

Dupa compilare nu am obtinut erori.

Sigur am si alte probleme.Si la asta trimis de dvs. da eroareArduino: 1.8.3 (Windows 7), Board: "Arduino Nano, ATmega328" ceva de genul:

C:\Users\FANE\Documents\Arduino\sketch_jul20a\sketch_jul20a.ino:9:20: fatal error: rotary.h: No such file or directory

#include <rotary.h>

^

compilation terminated.

exit status 1

Error compiling for board Arduino Nano.

This report would have more information with

"Show verbose output during compilation"

option enabled in File -> Preferences.

Nu ai instalat biblioteca "rotary".

[fane]

Am inteles multumesc. M-am uitat mai atent si asta e sketciul pentru generatorul de fregventa pe care il am facut deja si merge

probleme am avut la el din caza encoderului care are doua rezistente smd pe placa si din cauza lor nu lucra,l/am scos si e ok.

Dupa cum am spus acum incerc sa lucrez cu un tft display pe care nu reusesc nicicum sa il fac sa afiseze ceva am incercat o gramada de sketciuri de pe saiturile indicate de autori si nu reusesc.

[MVS]

fane: reciteste-mi postarea #11.

[nico_2010]

@fane: ce model de afisor TFT folosesti si care este circuitul driver pentru el? O fotografie face cat o mie de cuvinte!

[fane]

atasez poze cu cele doua displaiuri pe care le am, nu stiu ce circuit driver folosesc??

si cel de a doilea

Editat Iulie 22, 2017 de fane

[MVS]

pentru al doilea asta este driverul:

https://github.com/prenticedavid/MCUFRIEND_kbv

pentru primul nu sunt sigur. mai caut si revin cu info.

 

 

Editare ulterioara:

 

pentru primul:

Driverul este SPFD 5408.

[fane]

Va multumesc pentru ajutor si intelegere, dar cred ca problema sint eu nu schetciurile sau placile. Nu stapinesc lucrul cu programul si librarii multiple.Cred ca trebuie sa ma apuc de studiu si sa depasesc stadiul de inccepator 0.E mai amplu sistemul de lucru si trebuie tratat cu mai multa atentie.
