2.3 Quick Start The ATAVRAUTO102 board can be used to analyze up to one CAN and two LIN net-
works. Connect networks (LIN and/or CAN) and plug USB cable.
Figure 2-1. Board connections and default jumpers settings
Note: At least one “VBat” should be connected to have the LIN interfaces working.
The default configuration allows to use the board with LIN and CAN.
Note: For more details on ATAVRAUTO102 options, please refer to “Using
ATAVRAUTO102” chapter of the user guide.

Using the ATAVRAUTO102
3.1 Using the ATAVRAUTO102 board
The ATAVRAUTO102 can be used as a spy on a network or can act as a single Slave or
Master node.
LIN0 can be sniffer/slave or master.
LIN1 can be sniffer or slave.
CAN can be sniffer or master.
Steps to follow:
Connect your board to your PC using the USB cable.
Link all networks you want to work with.
If LIN0 is a master node, set the jumper MAST.
Run “X-Analyser”.
3.2 Updating the ATAVRAUTO102 firmware
For the future firmware revision, the ATAVRAUTO900 will be used to update
AT90CAN128 and AT90USB1287 microcontrollers.
Note: When programming, NISP_C and NISP_U jumpers have to be removed.
The AT90CAN128 and the AT90USB1287 can be programmed using specific SPI links.
This sub section will explain how to connect the programmer.
The FLASH, EEPROM memory (and all Fuse and Lock Bit Option ISP-programmable)
can be programmed individually or with the sequential automatic programming option.

3.2.1 Using the
ATAVRAUTO900
Adaptor
The AVR ISP is a compact and easy-to-use In-System Programming tool for developing
applications with AT90CAN128. Due to the small size, it is also an excellent tool for field
upgrades of existing applications. It is powered by the ATAVRAUTO102 and an addi-
tional power supply is thus not required. The AVR ISP programming interface is
integrated in AVR Studio®. An additional adaptor has to be used to program the board
using ISP or JTAG mode. The 10 pins connector is used for the JTAGICE mkII device
and the 6 pins connector is used for the AVRISP device. To plug the ATAVRAUTO900
connector to the board, the arrow (on the adaptor) has to be in front of the point (on the
board).

3.2.2 Programming with
AVR ISP via SPI
Both the Flash and EEPROM memory arrays can be programmed using the serial SPI
bus while RESET is pulled to GND. The serial interface consists of pins SCK, MOSI
(input) and MISO (output). After RESET is set low, the Programming Enable instruction
needs to be executed first before program/erase operations can be executed. Note that
throughout the description about Serial downloading, MOSI and MISO are used to
describe the serial data in and serial data out respectively. For AT90CAN128 these pins
are mapped to PDI (PE0) and PDO (PE1).
To program the device using AVR ISP programmer, connect the AVR ISP to the adaptor
(ATAVRAUTO900) and connect the adaptor to the connector of the ATAVRAUTO102.

3.2.3 Programming with
AVR JTAGICE mkII
The AT90CAN128 can be programmed using specific JTAG link: 3-wire debug-wire
interface. To use the AVR JTAGICE mkII with an ATAVRAUTO100 an optional adaptor
should be used. Then the JTAG probe can be connected to the ATAVRAUTO100 as
shown in the following figure.

3.3.1 Speed limitations • The limitation of the USB HID Class implies a limitation if the bit rate : the maximal
HID baudrate is 64 KByte/s, so 512 Kb/s. So, for a CAN Baudrate higher than
500Kb/s, a CAN load higher than 50% will imply the loss of CAN frames.
• The Windows Operating System also implies limitations for the application: If
ATAnalyser is the only running application, the O.S. allows the application to
received USB frames only every 10 ms. A buffer permits to save received USB
frames but for very high bitrates, there could be a loss of received USB frames.
