İyi akşamlar arkadaşlar. Bir projede takılı kaldım. Yardımcı olursanız çok sevinirim. Kullanmış olduğum kod sıcaklık ve voltaj sensörleri içeriyor. Bu veriKodu leri işleyerek 2x16 ekrana bilgi gönderiyor. Ayrıca fan devreye alıyor. Ve butonlarla menü değişiyor. Kodda bir problem yok. Gayet güzel çalışıyor. Benim istediğim kod verilerini nrf24lo1 kullanarak kablosuz olarak başka bir ardunio ve 2x16 ekrana taşımak. Orjinal kod ekranlı ve verici olacak. Diğer arduino ekranlı ve alıcı olacak. orjinal koddaki sensör girişleri ve ekran çıkış pinlerinin nrf24l01 pinleri ile çakışmaması lazım. Orjinal kodu sizinle paylaşıyorum. Umarım destek olacak bir arkadaş çıkar. Bu arada chatgpt kullandım. Fakat tam istediğim kodu veremedi. Yada ben yalnış yönlendirdim. // PA-Monitor-SG-Lab-2GHz4-V2.ino ---------- c 2020 by DC5ZM ------------------------------------------------------- // // PCB for UNO and NANO are available by weber.r1@t-online.de // // ---------------------------------------------- include libraries -------------------------------------------------- #include <OneWire.h> #include <DallasTemperature.h> #include <LiquidCrystal.h> // ---------------------------------------------- define constants --------------------------------------------------- LiquidCrystal lcd(8, 9, 4, 5, 6, 7); //allocate uno pins to LCD diplay pins(rs,enable,DB4,DB5,DB6,DB7) #define ONE_WIRE_BUS 12 // Data wire is plugged into pin 12 on the Arduino #define TEMPERATURE_PRECISION 13 #define FAN_PIN 11 #define NO 0 #define YES 1 // ************************************************************** variables to be changed for calibration ********* // use https://www.xuru.org/ for calculation coefficients * * // formula used: y = a +b*x + c*x*x * // * float a_drv = -0.087, b_drv = 13.615, c_drv = 61.081; // coefficients of polygon approximation DRV * float a_fwd = 0.491, b_fwd = -1.099, c_fwd = 1.661; // ...
