This manual provides programming examples and code for the Microchip PIC16F877 microcontroller, covering SPI, PWM, A/D and sleep mode.
The document is a learning service manual for the PIC16F877 microcontroller. It contains source code examples, register settings and step‑by‑step explanations for common peripheral modules such as PORTD, SPI, A/D converter, PWM (CCP) and the sleep mode. The material is organized by functional blocks, each with initialization routines and usage notes.
Key sections include PORTD configuration for an 8‑LED display, SPI initialization and data transfer routines, A/D setup for the RA2 pin, PWM configuration for CCP1, and a sleep‑mode example. The manual also provides utility functions like delay loops and interrupt handling to help developers integrate these features into their projects.
