A GOOD EXPERIMENTAL TOOL for project designs. 96 line TTL I/O card is an add-on card to an IBM computer. It requires one slot of the motherboard. It provides 96 TTL/DTL compatible digital I/O lines using four numbers of industries standard 8255s. Each 8255 IC consists of three ports, an 8bit PA, PB and PC port. The PC port may also be used as two half ports of four bits, PC upper (PC4-7) and PC lower (PC0-3). Each of the ports and half ports may be configured as input or an output by software control according to the contents of a write only control register in the PPI. The PA, PB, & PC ports may be read as well as written into. In addition, certain other configurations are possible for unidirectional and bi-directional strobed I/O, where the PC ports are used for control of data transfer. In this digital I/O card, 16 I/O mapped I/O address locations are used, which are fully decoded within the I/O address space of the IBM PC. The base address is set by a position jumper connection. This allows the user to configure the I/O address without conflicting with other I/Os used or designed within the instrument. Programming is simple whether from assembly language, BASIC, C, C++, PASCAL, assembly, VISUAL BASIC, VISUAL C++ or any other higher level languages. The digital I/O card should first be configured in the initialization section of your program by writing the control register. On power up or reset, all ports are configured as inputs. A variety of configurations are possible by writing the appropriate control code. The 8255 can be programmed in three different modes. Mode 0 - Basic I/O, all ports is I/O ports. Mode 1- Strobed I/O, part of the PC port controls data transfer. Mode 2 - Strobed bi-directional bus. A sample program in BASIC It is assumed that a switch /LED module, Model IM-6 is connected to this digital I/O card. Where PB is connected to 8 bit Switch inputs and PC is connected to an array of 8 buffered LEDs.
