STM32F103C8T6 16x2 LCD HAL Kütüphanesi

Herkese merhaba,

Youtube'da başlatmış olduğum CubeMX ile STM32F103 programlama serisinde kullandığım LCD HAL kütüphanesini burada paylaşıyorum.

Öncelikle kütüphanenin orijinalinin bulunduğu blog sayfasının linkini paylaşmak istiyorum.

 Kullanim : CubeMX ile proje olustururken 6 adet GPIO pini
       asagidaki gibi tanimlanmalidir.
       
  No.  | Pin Name| Type | Alt. Func. | Label
  ----------------------------------------------
        xx  | Pxx   | I/O  | GPIO_Output | LCD_RS
  xx  | Pxx   | I/O  | GPIO_Output | LCD_EN
  xx  | Pxx   | I/O  | GPIO_Output | LCD_D4
  xx  | Pxx   | I/O  | GPIO_Output | LCD_D5
  xx  | Pxx   | I/O  | GPIO_Output | LCD_D6
  xx  | Pxx   | I/O  | GPIO_Output | LCD_D7
     
  Pin ve port farketmeksizin, Output olarak tanimlanan pinler
  yukaridaki gibi isimlendirilmeli ve baglanti gerektigi gibi
  yapilmalidir.      
      
  Init Örnegi:       
  lcd_init(_LCD_4BIT, _LCD_FONT_5x8, _LCD_2LINE);
     
  4-Bit, 5x8 Font'lu, 2 satirli display kullanilacagi belirtiliyor.
  Farkli varyasyonlara LCD.h dosyasindan bakabilirsiniz.
                           
        Kontrast ayari için pot kullanmak istemiyorsaniz baglantiniz asagidaki 
        gibi olmalidir.
