PIC16F84A interrupt based software UART

PIC16F84A interrupt based software UART code and Proteus simulation

This post provides the interrupt based software UART (Bit Banging) code for PIC16F84A microcontroller. As we know, PIC16F84A microcontroller doesn’t have built in UART module, so we can create UART functionality in it’s software. This post provides the details of how to program software UART functionality in PIC16F84A. This code is written in C language using MPLAB with HI-TECH C

GSM Alarm

Tiny GSM alarm system using PIC16F84A

After GSM call alarm and GSM SMS alarm as two independent modules, I introduce the Tiny GSM alarm system. The main characteristic of this new version is that this device can operate standalone or as a module for existing alarm system. In previous versions we had only the “enable” pin that armed/disarmed the system. Now, aside from that pin we can arm/disarm the
