===== Paper-AVRISP mkII ==== An AVRISP mkII clone made out of Paper-PCBs.\\ {{:avr_bootloader:paper-avrisp_mkii.jpg|}}\\ The controller is a cheap ProMicro with the Atmel32U4 chip. The design is based on the [[http://make.kosakalab.com/make/electronic-work/avrisp-mk2/leo-r3_avrisp-mk2_en/| Make the AVRISP mkII Clone from Arduino Leonardo / Micro]] by Kimio Kosaka.\\ Front:\\ {{:avr_bootloader:paper-avrisp_mkii_front.jpg?400|}}\\ Back:\\ {{:avr_bootloader:paper-avrisp_mkii_back.jpg?400|}}\\ ---- ==== Pro Micro Modification ==== ** TX Line Connection:**\\ Solder a wire between the resistor of the TX LED and A0.\\ {{:avr_bootloader:promicro_txledconnection.jpg?400|}}\\ ** Close the Jumper: **\\ The Chinese Pro Micro clones have a 5V converter on board. That means when powered over USB the Pro Micro runs on 4.7V. To close the jumper will avoid that (it´s next to the USB socket). But never power the Pro Micro over the RAW input again! Check the [[http://cdn.sparkfun.com/datasheets/Dev/Arduino/Boards/SparkFun_Pro_Micro_v13a.pdf|original sparkfun schematic]] for details.\\ In putting a little bit of solder on J1 of the Pro Micro Clone you close the jumper and bypass the voltage converter of the board. **Pin Out:**\\ {{:avr_bootloader:promicro_pinout.jpg?400|}}\\ ---- ==== Paper-PCB ==== {{:avr_bootloader:paper-avrisp_mkii_02.jpg?400|}}\\ {{ :avr_bootloader:paper-avrisp_mkii_02.zip |}}\\ ---- ==== Software ==== Connect an AVR programmer to the Pro Micro: +5V, GND, Reset, MISO, MOSI, SCLK.\\ ! It should be the Reset pin on the Pro Micro board not the one of the connector !\\ With the Avrdude erase the Arduino Pro Micro:\\ $ sudo avrdude -p m32u4 -c stk500v2 -P /dev/ttyACM0 -e Set the fuses like that: lowFuse 0xFF, highFuse 0xD9, extendedFuse 0xC3:\\ $ sudo avrdude -p m32u4 -c stk500v2 -P /dev/ttyACM0 -U lfuse:w:0xFF:m $ sudo avrdude -p m32u4 -c stk500v2 -P /dev/ttyACM0 -U hfuse:w:0xD9:m $ sudo avrdude -p m32u4 -c stk500v2 -P /dev/ttyACM0 -U efuse:w:0xC3:m Burn the ATMega32U4-usbdevice_dfu-1_0_0.hex file on the Pro Micro. The file is included in the megaUSB_DFU_Bootloaders_2 folder:\\ [[http://make.kosakalab.com/archives/megaUSB_DFU_Bootloaders_2.zip]]\\ $ sudo avrdude -p m32u4 -c stk500v2 -P /dev/ttyACM0 -U flash:w:ATMega32U4-usbdevice_dfu-1_0_0.hex:i Set Lock-Bits 0xEF:\\ $ sudo avrdude -p m32u4 -c stk500v2 -P /dev/ttyACM0 -U lock:w:0xEF:m Run the [[http://www.atmel.com/tools/FLIP.aspx|Atmel Flip-Tools]] like it's described at [[http://make.kosakalab.com/make/electronic-work/avrisp-mk2/leo-r3_avrisp-mk2_en//|Kimio Kosakas page]].\\ Upload that file:[[http://make.kosakalab.com/archives/AVRISP-MKII_ATmega32u4.zip]].\\ That's it! Test it with an Atmega 328p:\\ $ sudo avrdude -p m328p -c avrispmkII -P usb -U flash:w:optiboot_atmega328.hex:i ---- ==== Knowledge ==== === The Arduino Pro Micro === [[https://www.sparkfun.com/products/12640]]\\
