@brief Support for the Mega1284P-Xplained board.
|
|
|
|
### General information
|
|
|
|
The [Mega1284P-Xplained](http://www.microchip.com/DevelopmentTools/ProductDetails.aspx?PartNO=atmega1284p-xpld)
|
|
is an evaluation kit by Atmel (now Microchip) for their ATmega1284P microcontroller.
|
|
|
|
### Flash the board
|
|
|
|
You can change the fuses and flash the board using an SPI ISP programmer such
|
|
as the Bus Pirate, or using a JTAG programmer such as the Atmel-ICE with a
|
|
JTAG adapter.
|
|
|
|
If using the Atmel-ICE as a JTAG programmer, connect the adapter with the
|
|
square pin on the adapter connecting with the square pin on the board.
|
|
|
|
1. First, make sure the default fuse settings are correct.<br/>
|
|
|
|
WARNING: setting the fuses incorrectly can brick your board!
|
|
|
|
If using the Buspirate:
|
|
```
|
|
avrdude -p m1284p -c buspirate -P /dev/ttyUSB0 -U efuse:w:0xFF:m
|
|
avrdude -p m1284p -c buspirate -P /dev/ttyUSB0 -U hfuse:w:0x99:m
|
|
avrdude -p m1284p -c buspirate -P /dev/ttyUSB0 -U lfuse:w:0xE2:m
|
|
```
|
|
|
|
If using the Atmel-ICE:
|
|
```
|
|
avrdude -p m1284p -c atmelice -U efuse:w:0xFF:m
|
|
avrdude -p m1284p -c atmelice -U hfuse:w:0x99:m
|
|
avrdude -p m1284p -c atmelice -U lfuse:w:0xE2:m
|
|
```
|
|
|
|
2. After the fuses are set, flash the application.
|
|
|
|
If using the Buspirate:
|
|
```
|
|
BOARD=mega-xplained make -C examples/hello-world flash
|
|
```
|
|
|
|
If using the Atmel-ICE:
|
|
```
|
|
BOARD=mega-xplained PROGRAMMER=atmelice make -C examples/hello-world flash
|
|
```
|
|
|
|
### Accessing STDIO via UART
|
|
|
|
STDIO can be accessed through the USB connector. The on-board UART-USB
|
|
adapter is not affected by flashing. It shows up as /dev/ttyACM0 on Linux.
|
|
It will be used automatically with `make term`:
|
|
```
|
|
BOARD=mega-xplained make -C examples/hello-world term
|
|
```
|
|
|
|
### Pin Change Interrupts
|
|
|
|
More pins can be used for hardware interrupts using the Pin Change
|
|
Interrupt feature. See @ref boards_common_atmega for details.
