How to connect the development system?
The mikroXMEGA development system can be easily connected to external devices via connectors and pads supplied
on the board. The USB connector is used to connect the USB-UART module of the development system to a PC. In
order to use the USB-UART module, it is necessary to select which UART module of the microcontroller will be used.
This is done via jumpers J1-J4. In order to use PC2 (RX) and PC3 (TX) pins, jumpers J1 and J3 should be placed.
Likewise, in order to use PD2 (RX) and PD3 (TX) pins, jumpers J2 and J4 should be placed.
The CN4 (PDI) is used for programming/debugging via PDI interface. The CN5 (JTAG) connector is used for
programming/debugging via JTAG interface.
The CN1 and CN3 pads enable the microcontroller pins to be easily accessed. The 3.3V power supply voltage is
supplied to the pads marked 3.3V (+3.3V) and GND.
mikroXMEGA
The mikroXMEGA is a compact development system that enables you to experiment with the ATxmega128A1
microcontroller from Atmel®.
Key features:
- Bootloader program loaded into the ATxmega128A1 microcontroller;
- USB-UART communication;
- JTAG connector;
- External power supply 3.3V.
