![]() The circuit was designed in Proteus 7 Professional and the code was written in Assembly Language. The code was comipled into an executable file via EMU 8086 application. The executable file was loaded into the design and the simulation was run.īelow are some of the screen shots of the circuit designed and the humidity output. 8086 microprocessor interfacing circuit to demultiplex address and data linesħ4LS373 (Octal Latch) for Address de-multiplexingħ4LS245 (8 bit bi-directional buffer) for Data de-multiplexing.Memory Interfacing along with peripheral I/O Interfacing.READ and WRITE Enable for EVEN and ODD Banks of ROM and RAMĨ255 chip select logic (base address of 8255 = 00H) 8255 PPI, Humidity output signal processing and LCD display.Humidity sensor modelled as a VCCS (Voltage Controlled Current Source) along with a potentiometer to change output current The humidity sensor in the above circuit was modelled by a Voltage Controlled Current Source (VCCS) and the voltage was changed by using a potentiometer.
