Step 2:
Connect Host to Bootloader
1. Open the serial bootloader host PC software
(AN1310ui.exe).
2. If this is the initial setup, configure the serial port
and bootloader baud rate by selecting
Program>Settings
.
The dialog box in Figure 2 appears.
FIGURE 2: SETTINGS DIALOG BOX
3. Select values for the “COM Port” and
“Bootloader Baud Rate” fields and click OK.
Using a moderate speed “Bootloader Baud
Rate”, such as 19.2 kbps, may help with initial
communications. Non-standard, high-speed
baud rates can be attempted once everything is
working.
The software allows serial communication with
application firmware after programming. Appli-
cations can require a particular baud rate, so a
separate “Application Baud Rate” setting is pro-
vided. For the example application firmware
projects, the 115,200 bps rate is suggested.
4. Connect the PC's serial port to the PIC MCU
development board.
5. Go into “Bootloader” mode on the PC by clicking
the red bootloader software button, shown in
Figure 3, or pressing the PC’s <F4> key.
The PC software attempts to communicate with
the PIC bootloader firmware, using the specified
bootloader baud rate. If communications are
established, the PC displays the bootloader
firmware revision and the PIC device’s
information, as shown in Figure 3.
