Здравейте
След помощта на съфорумниците успях да подкарам флоат аритметиката. MPLABa все още не успявам да го накарам константите да ги изкарва правилно но поне променливите излизат вярно. И sprintf() работи. Голямо улеснение. Всичко е наред, програмата си работи ОК. Обаче на прототипския процесор. А той е с памет за 8000 инструкци. В момента използвам ≈3500инструкции. Всички оптимизации са включени. Дали ще е възможно да намаля кода на програмата като изключа по някакъв начин функциите които не се използват. Примерно:

Това ми е началото на програмата:
| | |
| Код: #include <htc.h> #include <stdio.h> #include <math.h> #include "delay.c" #include "delay.h" #include "s_lcd.h" #include "sht11.h" | |
| | |
Забелязвам че примерно като изтрия функциите за закъснение от delay.c, който не ползвам, размера на кода намалява. Не знам дали със math.h и stdio.h ще се получи същият ефект. А иначе доста функции не се използват.
Използвам HI-TECH PICC 9.50.
Предварително благодаря на всички отговорили
