- Page 9 2.4.4 Current measurement 2.4.5 Speed/Position measurement inputs ATAVRAUTO200 User Guide Motor current is measured using a shunt resistor. External differential amplifier (on board) is connected to ADC to measure shunt resistor voltage. Amplifer output (current image voltage) is connected to ADC0 pin for current acquisition AIN1 pin to detect max current peak (compared to AIN0 through internal analog comparator)

Using the ATAVRAUTO200 2.4.6 2.4.7 BOOT In-System Programming 7698A–AUTO–01/07 The ATAVRAUTO200 includes one green LED implemented on one I/O pin. It is con- nected to the “PortD Pin3” of the ATmega48/88/168. To light On the LED, the corresponding port pin must drive a low level. To light Off the LED, the corresponding port pin must drive a high level. - Page 11 2.5.1 Using the ATAVRAUTO900 Adaptator ATAVRAUTO200 User Guide An additionnal adaptator has to be used to program the board using IPS 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.
