ODAS System Block Diagram

The Open Data Acquisition System consists of a Data Acquisition Processor (DAP) and I/O cards.

The block diagram is:

Maximum Configuration

MCP23017 (16 port I/O expander) uses (1) I2C address in range 0x20-0x27
I2C supports up to 8 MCP23017 I2C addresses typically
Up to 64 cards can be supported with a single [I2C-RPT-08|8 port I2C repeater]]
- Ex: If a DIGIO-128 card is used with an 8 port I2C repeater, this provides 1024 digital I/O pins
Up to 8 of 8 port I2C repeaters can be used
- (64) DIGIO-128 cards would result in 8,192 bits of digital I/O
- Each 8 port I2C repeater has a base address of 0x70-0x77

Host Software - Firmata

Firmata is a generic protocol for communicating with microcontrollers from software on a host computer. It is intended to work with any host computer software package. Right now there is a matching object in a number of languages. It is easy to add objects for other software to use this protocol. Basically, this firmware establishes a protocol for talking to the Arduino from the host software. The aim is to allow people to completely control the Arduino from software on the host computer.

Firmata has an attractive Test Program User Interface which could be easily extended

Personality EEPROM

Useful when there are a lot of I2C cards in a system
- Useful in card test
- Configure the card once, autodetect later
EEPROM I2C base address = 0x50
