Tiny Bootloader and 18F1320 Through X-bee wireless
Just got Tiny Bootloader to work with my X-bee network. Changed the .asm file to look like this so it runs at 9600 baud @4MHz
Code:radix DEC LIST P=18F1320 ; change also: Configure->SelectDevice from Mplab xtal EQU 8000000 ; you may want to change: ;oscil: _HS_OSC_1H HS extern ; _INTIO1_OSC_1H Internal RC, OSC1 as RA7, OSC2 as Fosc/4 ; _INTIO2_OSC_1H Internal RC, OSC1 as RA7, OSC2 as RA6 baud EQU 9600 ; standard TinyBld baud rates: 115200 or 19200 ; The above 3 lines can be changed and buid a bootloader for the desired frequency and PIC type #define _XTAL_FREQ 4000000 ;//set your xtal frequency here #define _UART_BAUD 9600 ;//set your baud rate here #define _UART_BRG ((_XTAL_FREQ / _UART_BAUD) / 64) - 1 ;//variable for setting SPBRG ;SPBRG = _UART_BRG ;//set baud rate ; TXSTA = 0b00100000; ; //tx enable, low speed baud rate generator ;RCSTA = 0b10010000; //serial port enable, continuous rx enable ;******************************************************************** ; Tiny Bootloader for 18F series Size=100words ; [email protected] ; http://www.ac.ugal.ro/staff/ckiku/software/picbootloader.htm ;******************************************************************** #include "../icdpictypes.inc" ;takes care of: #include "p18fxxx.inc", max_flash, IdTypePIC #include "../spbrgselect.inc" ; RoundResult and baud_rate
