Physical Connections
The Emic Platform can be integrated into any design using a minimum of five connections (VCC, GND, SIN, SOUT,
and AOUT). Optional status and control pins are also available if desired. Though many configurations are possible, a
typical connection diagram to a microprocessor uses eight connections (VCC, GND, SIN, SOUT, BUSY, /RESET,
SP-, SP+).
Communication Protocol
The Emic Platform is controlled by the host via an easy-to-use, TTL-level, asynchronous, two-wire serial
communications interface. The SIN (Serial Input) pin receives data and commands from the host controller to the
Emic Platform. The SOUT (Serial Output) pin transmits data and responses to the host controller from the Emic
Platform.
The Emic Platform can connect directly to any TTL-compatible UART or to an RS232-compatible interface by using
an external level shifter.
All communication is 8 data bits, no parity, 1 stop bit, non-inverted, least significant bit first (8N1). The baud rate is
configured in the Emic Platform firmware for 2400 baud, a standard communications speed supported by the BASIC
Stamp microcontroller, the Javelin Stamp microcontroller, and most any other microcontroller or PC. The host
controller must initiate all communication. The Emic Platform does not initiate any communication. Refer to the
section on Command Structure for a list of available commands.
