3. Programming the microcontrollerFigure 3-1:ATxmega128A1MicrocontrollerThe microcontroller can be programmed in two ways:01 Over UART mikroBootloader02 Using external PDI programmerPage 11

Programming with mikroBootloaderYou can program the microcontroller with UART bootloader whichis pre programmed by default. To transfer .hex file from a PC toMCU you need bootloader software (mikroBootloader) whichcan be downloaded from:mikroBootloader ikromedia xmega bootloader v101.zipAfter the mikroBootloader software is downloaded unzip it todesired location and start it.Figure 3-2: mikroBootloader window01Page 12When you start mikroBootloader software, a windowas shown in Figure 3-2 should appear

Your program will runautomaticallyPage 17

Programming with externalprogrammerThe microcontroller can be programmed with external programmer (AVRISP mkII, AVRJTAGICE mkII or other supported programer with PDI interface). The externalprogrammer is connected to the development system via pads marked withPDI (CN5), Figure 3-11. In order to connect the external programmer tothe development system, it is necessary to solder a 2x3 male headeron the pad (CN5). If bootloader program is accidently erased you canupload it again via external PDI programmer. Programatxmega128a1 bootloader firmware.hexcan be found under Firmware folder(page 12).Figure 3-11:connecting PDIprogrammerPage 18
