... Xplained Getting Started preprogrammed firmware. The preprogrammed AT32UC3B1256 for self-programming of the board controller itself, and a USART-to-USB gateway, which can be used to communicate with the target controller, the ATmega1284P. Atmel ATmega1284P ATmega1284P is set up with example code that ATmega1284P without using an Guide, for ...

... As some of the other ICs on the Atmel MEGA-1284P Xplained require 3.3V to operate correctly, these devices have to be removed. As part of an ATmega1284Pevaluation, it can be of interest to measure its power consumption. The two-pin power measurement header is the only connection between the VCC_P3V3 common power plane and the VCC_MCU_P3V3 power plane ...

... Memories 8377B-AVR-11/11 The Atmel MEGA-1284P Xplained kit does not have any external memories mounted on the board. Footprints are available for adding either an industrial standard flash device or an Atmel proprietary serial DataFlash device. The footprints share the same SPI lines, including the chip select, and it is, therefore, not possible to mount devices on both footprints at the same time ...

... The RC filter (first-order low-pass) has an approximate 3dB cut-off frequency of 159Hz. The input to the RC filter is GPIO5 (PD5) on the ATmega1284P, which can be configured to output a PWM signal to the RC filter. This can be used to generate a DC voltage on the output of the RC filter, which can be measured on the ADC5 pin. ...
