EasyAVR M1280 SK is one of AVR study and development tools designed and manufactured by AVRVI. And it is based on Atmega 1280 and integrates AVRISP MKII programmer. With EasyAVR M1280 SK and a computer, then users could learn embedded systerms.

Features:

There are many useful resources integrated on the development boards, such as: LED, press key, seven-period nixietube, RS232/LCD/CAN/DAC/PS/2 interfaces and AVRISP MKII programmer.
EasyAVR M1280 SK adopts signal conditioning circuit which allows users to input 0-10v voltage.
The core bord can be taken apart from the backplane, which allows users to choose other core board such as: Atmega2560, Atmega 640, Atxmega128A1 etc.

Experiments or demos included in our CD

A/D convertion
1. Results collected by AD single channel will be displayed on Seven-period nixietube
2. serial debugging assistant will detect datas collected by AD double channels
3. analogs will be sent to AD module by simulation temperature sensors TC1047AVNBTRTC1047AVNBTR and will be displayed via seven-period nixietubes after analogs have been tranferred.
4. After frequency-division operation to the clock signal from DS1337, it could initiate interruption and meanwhile, Meanwhile,times the interruption has occured will be accumulated on the seven-period nixietube from zero.

buzzle:

When users press the key to test, the buzzer will make a buzz sound.

matrix keyboard
1. When users press the key to test, the buzzer will make a buzz sound.
2. When users press the key to test, the seven-period nixietube will shows a number which represents which key you have pressed.
LED
1. users could set synchronized flow control lamp procedures
2. users could set LED turning bright at random
Timer

Timer T1 could realize one-second timing and seven-period nixietube will display the results

TC1047A/TC72
1. TC1047A/TC72 will detect the temperature and the results will be displayed on the seven-period nixietube
2. TC1047A/TC72 will detect the temperature and serial debugging assistant will tell the results
SPI
1. using SPI to drive 74HC595 to achieve the seven-period nixietube display.
2. Using SPI to drive TC72 to read the temperature and achieve the seven-period nixietube display.
3. Using SPI to drive MCP4922 to achieve the A/D conversion and output the voltage
TWI
1. using TWI to drive 24C01
2. Using Twi to drive DS1337
24C01
1. using 24C01 to read and serial debugging assistant to check the results
2. using 24C01 to record on-off times of this device and display the number on the seven-period nixietube
DS1337
1. DS1337 is a real time clock and the seven-period nixietube will display the time.
2. use DS1337 for timing and the buzzer will make a buzz sound
LCD1602

Use LCD1602 to display information

4*4 matrix keyboards

The seven-period nixietube can display the corresponding number showing which key has been pressed

debounced keyswish composed of 74HC00D

when the key1 or key2 has been pressed down, the seven-period nixietube will show the accurate times thanks to debounced keyswish

MCP4922

Users can use MCP4922 to convert digital to analog and ouput the analog voltage

Realize the conversion between two CAN devices

PS/2 device

Use LCD1602 to show the corresponding ASCII of the key which has been pressed down

USART

The serial port receives the data.(The microcontroller can send the data to the serial port automatically and the serial debugging assistant will check the datas)
