#HOW TO GET VOLTMETER IN PROTEUS 8 DRIVER#
Control signals for the display driver transistors Q1 and Q2 are obtained from P3.2 and P3.1 of the microcontroller. 2 digit multiplexed seven segment display is interfaced to Port0 of the microcontroller. Control signals for the ADC ie CS, RD, WR and INTR are available from the P3.7, P3.6, P3.5 and P3.4 pins of the microcontroller respectively.

Digital output of the ADC is interfaced to P1.0 of the microcontroller. In this circuit, for an input voltage of 1V the digital output will be 1/19.6mV = 51 and so the binary equivalent of 51 ie 00110011. The equation for the digital output of ADC0804 is Dout = Vin/Step size. 2, in order to model a PV panel in Proteus tool, the below steps are followed: 1. The PV panel model under Proteus As shown in Fig. In the circuit Vref/2 (pin9) of the ADC is left open and it means that the input voltage span can be o to 5V and the step size will be 5/255 = 19.6mV. 2 presents the Proteus model and its Spice code.
