Últimamente he intentado conectar la interfaz HC-SR04 con PIC16F877A utilizando el modo de captura e interrupción, pero recibo "Advertencias" y pegué el código a continuación:

Incluso si usas MPLab IDE, el código que estás escribiendo sigue siendo C.

xC8, xc16 y xc32 El XC8, XC16 y XC32 son compiladores para los procesadores PIC de Microchip. XC8 se utiliza para MCU de 8 bits, XC16 para MCU de 16 bits y XC32 para MCU de 32 bits. Aquí obtendrá una visión general clara de los compiladores

El C18 era un antiguo compilador para MCU de 8 bits. Si recién comienza a programar los PIC, use el equivalente a XC :-)

Advertencias de Pragma

Ya te mostré la Guía de migración . Para obtener la advertencia en la línea 23 de distancia, escriba 

void My_HiPrio_Int @ 0x0008 (void)

en lugar de 

#pragma code My_HiPrio_Int=0x0008
void My_HiPrio_Int(void)

¡Echa un vistazo claro a la página 34 para esto!

La declaración pragma en la línea 36 ya no es necesaria cuando se compila con XC8 en lugar de C18.

Para evitar la advertencia en la línea 30, puede escribir 

 void interrupt chk_isr(void)

en lugar de 

 #pragma interrupt chk_isr
 void chk_isr(void)

La página 32 te ayudará con esto ;-)

conversión de puntero ilegal

Intentas enviar un const -String con la función strdis() . Escribe 

 void strdis(unsigned char const  *str)

para mostrar al compilador que los valores del puntero no se sobrescribirán en la función (espero que esto funcione, no tengo el compilador XC8 con nosotros, lo siento). De lo contrario, puede hacer una conversión de tipo al llamar a strdis() . Por ejemplo: 

 strdis((unsigned char *)"Hello")

¡Pero no lo recomendaré! ¡Incluso si sabes lo que haces!

Último en la línea 83 que escribes 

 F_byte=(F_byte * 0.5);

En su lugar, escribe lo siguiente 

 F_byte=(F_byte / 2);

Al calcular con números flotantes, el compilador hará una conversión de tipo por sí mismo. Así que convierte F_byte a un flotador y luego se multiplica con 0.5 . float -calculación es mucho más lento que integer -cálculo, por lo tanto, evite esto siempre que sea posible.

Si encuentra algo como F_byte=(F_byte >> 1); en cualquier lugar de la www, puede estar seguro de que cada compilador, que está casi actualizado, hará la optimización de este código mientras compila.
