Pin 1 of the 6-pin ISP connector K13 is located nearest to the microcontroller module (Figure 5). If the target device is supplied with 3.3 V (or even less) during programming, It is worth remembering that the programmer uses 5 V logic levels. Then the new firmware can be loaded over the six-pin ISP connector using a second programmer. To reprogram the firmware it is necessary to bridge the two holes next to the quartz crystal on the programmer. If any problems arise it is worth checking to see if a new version of the firmware is available. Figure 4 shows how the ISP frequency is set in AVR Studio. From version 4.13, AVR Studio refuses to run the programmer at frequencies of less than 5 kHz. Since this software is driven from the command line, we have also made available a fileĢ49 Hz to 2 MHz.

For Linux and Mac OS X the open source ‘AVRDUDE’ software is particularly recommended. For non-Windows users there is a greater choice: do an internet search for ‘Linux’, ‘AVRISP MkII’ and ‘software’. Unfortunately, the programmer cannot be used directly with Bascom as that software does not yet implement the AVRISP MkII protocols. It is now possible to use the programmer with a wide range of software, including CodeVision AVR. Thanks to the use of a mini USB connector and a 6pin ISP connector the unit can be very compact. The programmer supports bit rates fromįigure 2. The ‘bitrate’ to which the programmer is set should not be greater than one quarter of the clock frequency of the microcontroller being used.
The solution is to operate the target device from 5 V during programming.

‘Elektor-AVRprog Mac.pdf’ which explains how to integrate AVRDUDE with a ‘proper’ user interface. The driver will nevertheless be found and installed and all will be well. Ignore this error message and click ‘Cancel’. In some Windows XP installations, however, an error message is produced, claiming that the file ‘libusb0.sys’ is not found. Module to the PC and Windows should then automatically recognise the new hardware and select the correct driver. A USB bridge and a microcontroller are the main components. After the driver has been installed we can connect theįigure 1: The circuit diagram of the Elektor USB programmer is broadly similar to its predecessor described in the October 2007 issue of Elektor.

Since we are using Atmel’s AVR Studio 4 with the test board, we can use it to install the relevant driver (see Figure 3). SOFTWARE Being a clone of the AVRISP MkII programmer, the Elektor design is compatible with a wide range of software. The May 2008 issue of Elektor will include a more detailed discussion of this. The printed circuit board (Figure 2) has been made smaller, thanks to the use of a miniature USB socket and a 6-way header rather than a 10-way header for the ISP interface.
#AVRISP MKII PROGRAMMER USER GUIDE PDF UPDATE#
In comparison to the earlier USBprog design the circuit has changed little (Figure 1), the main update being that an ATmega32 is used in place of the ATmega16.
The result was the simple dedicated USB programmer described here. The main requirement was that the programmer should be as simple in design and use as possible and as inexpensive as possible. It is particularly suitable for use with the ATM18 test board used in our microcontroller programming course. Elektor asked Benedikt Sauter to design a simple AVRISP MkIIcompatible programmer which can be used with a wide range of software. This companion to the Elektor AVR project is a plug-andplay AVRISP MkIIcompatible USB programmer for AVR microcontrollers.
