PIC16F887+UC00A+Bootloader+GSM *Urgent*

Postby wazier » Tue Feb 18, 2014 9:02 am

Hi there!
I really hope that someone can help me out. I just want to figure out is it possible for me to interface the GSM via the TX and RX of the PIC at the same time with the UC00A? I would like to use bootloader instead of ICSP to update the firmware each time. But I'm afraid it will affect the GSM connection and behaviour as it it attached at the same pins.
Plz I really need some clarifications about this.
Thanx!

You are right about the concern, both GSM and UART bootloader will interfere each other. Or you can put a switch to choose one of it these to activate at a time. Example a DIP switch or DPDT slide switch. When you want to use GSM, switch it to connect the PIC's UART pins to GSM only. When you want to load program, switch it to UC00A.
