PIC16F877的多任务 Salvo™ RTOS

This application note covers a Real-Time Operating
System (RTOS) running on a PIC16F877. The applica-
tion is written in C using the HI-TECH C compiler.
MPLAB
®
IDE is used as the Integrated Development
Environment. This RTOS is unique, in that it is intended
for microcontroller applications where memory is
severely limited. The application runs on a prototype
PCB that monitors temperature, accepts user input and
displays important temperature information.
