FLAGSTAFF, Ariz. The Firecard 20/24 data-acquisition system from Fire, Wind & Rain, one of the first to also include control and removable storage on one board, is for power systems, battery chargers and mobile apps requiring extensive real-time interaction.
The board, which uses a Z-180 processor running at 24.5 MHz, features a 12-bit A/D converter with eight channels, two resistive 8-bit ladder D/A converters, two pulse-width-modulated 8-bit converters with buffers, and 10 digital I/O lines. It has two serial ports with RS-232 drivers and a clocked serial output for a printer. The memory complement includes 1 Mbyte of fixed flash memory for data and program storage, a socket for 1 Mbyte of removable flash-memory cards, 64 kbytes of static RAM, 8 kbytes of E2PROM and 32 bytes of RAM with battery backup.
Development software is included. Firecard incorporates Firedos, an easy-to-use 8-bit flash-memory operating system for maintaining program and data files. Firedos supports various functions such as file lists, delete files, run program, create, load and save files, change file type, jump to RAM address, and read/write to and from RAM. For system maintenance, the Firecard also includes Firebasic, a full-featured, floating-point Basic interpreter that supports data files and multiple I/O devices. Because the interpreter and line editor reside on the Firecard, no PC is required. The Firecard features a footprint only 3.5 inches wide by 2.4 by 0.6. Firecard pricing starts at $199. Custom configurations are achieved through the card's reprogrammable logic array. Optional accessories such as serial cables, printer interface, demo boards and additional flash memory are also available.
