„Sziasztok!

Én mikroc-ben szeretnék programozni egy pic16f877-est az alábbi kondíciókkal:

PIC16F877
4Mhz

5db DS18B20 hőmérő
5db digitális bemenet úszókapcsolók jeleinek érzékelésére
4db digitális relés kimenet

Az összeépített vezérlőnek hőmérsékletet, valamint úszókapcsolókat kell figyelnie, melyeket LCD-re is ki kell írnia. Az LCD-vel egyidejűleg a soros portra is be kell küldenie, mért hőmérsékleti adatokat, valamint a portról fogadnia kell bekapcsolási parancsot a relék meghúzásához.
A mikroc helpje alapján összeraktam a kódot,de most tanácstalan vagyok hogy miért nem küldi megfelelően az adatokat.(lásd csatolt kép)

A kód maga így néz ki,de sajnos nem működik helyesen:

// LCD module connections

sbit LCD_EN at RD1_bit;
sbit LCD_D4 at RD4_bit;
sbit LCD_D5 at RD5_bit;
sbit LCD_D6 at RD6_bit;
sbit LCD_D7 at RD7_bit;

sbit LCD_RS_Direction at TRISD0_bit;
sbit LCD_EN_Direction at TRISD1_bit;
sbit LCD_D4_Direction at TRISD4_bit;
sbit LCD_D5_Direction at TRISD5_bit;
sbit LCD_D6_Direction at TRISD6_bit;
sbit LCD_D7_Direction at TRISD7_bit;
// End LCD module connections
