SUT AVR Assembler Laboratory Node Hardware Reference
Introduction
Each laboratory node is equipped with an Arduino Uno R3 development board, based on the ATmega328P MCU. It also has two extension boards:
- external, analogue and digital communication board,
- user interface board presented on the image 1.
There are 8 laboratory nodes. They can be used independently, but to present collaboration, nodes are interconnected symmetrically with GPIOs presented in a hardware reference section below
Hardware reference
The table ##REF:sutavrlabtable1## lists all hardware components and details. Note that some elements are accessible, but their use is not supported via the remote lab, e.g., buttons and a buzzer.
The node is depicted in the figure 1.

Communication
Devices (laboratory nodes) are interconnected in pairs, so it is possible to work in groups and implement scenarios involving more than one device:
- node 1 with node 2,
- node 3 with node 4,
- node 5 with node 6,
- node 7 with node 8.
Interconnections are symmetrical, so that device 1 can send data to device 2 and vice versa (similar to serial communication). Note that analogue inputs are also involved in the interconnection interface. See image 2 for details. [ktokarz]Inject image of interconnection below
Nodes are interconnected in pairs: 1-2, 3-4, 5-6, 7-8. Scenarios for data transmission between MCUs require booking and the use of correct nodes for sending and receiving messages.
