• The LCI - PIO card interfaces with the any Microprocessor kits and has the capability to display the binary contents of the CPU's internal registers, memory locations on LED's mounted on the LCI card.

This product is manufactured by DYNALOG.

• The contents are sent via the accumulator to the 8255 ports defined in the output mode to the LED's.
• The status of the 8255 A,B or C ports can be displayed on the LCI by interconnecting proper straps.
• On the LCI card, 16 LED's are mounted to indicate the logic states of the 16 bits.
• Each LED's is driven by a NOR gate (IC 74LS02).
• A current limiting resistor is connected in series with the LED.
• When the input of the NOR gate is logic 1 its output goes to logic 0.
• The current sink by the NORgate passes through the LED (and current limiting resistor) and the LED glows.
• Thus a logic 1 is represented by a glowing LED and logic 0 by an extinguished LED.
• The status of the 8255 A,B or C ports can be displayed on the LCI by interconnecting proper straps.

Note : All Dynalog Trainer kits except DSK starter kits can be used to study this card.

• The PIO-LCI card interfaces with the any of the Dynalog's Microprocessor kit.
• There is no need to have separate module for each and every kit.
• Quality product.
• They are designed to carry out different educational experiments for the purpose of thorough understanding of the peripheral chips commonly used with Microprocessor.
