 SPI Debugger

Hi Friends, in this post, we will discuss how to use SPI Debugger available in proteus for serial peripheral interface (SPI) which is a built-in feature of PIC microcontroller to communicate and data exchange between PIC and other devices.

Introduction to SPI

Guys, SPI can be considered as a programmable shift register, The SPI module is a synchronous serial I/O port that shifts a serial bit stream of variable length and data rate between the PIC and other peripheral devices. Here “synchronous” means that the data transmission is synchronized to a clock signal.

To avoid further delay, let's see some important connections and different configurations to effectively use SPI Debugger.

How to use SPI Debugger in MASTER & SLAVE configuration

Select the virtual instrument and from the instrument, list selects "SPI Debugger".

Insert two SPI Debugger on the working area, select any one of them, and right-click on it, navigate to edit properties.

In the "part reference" entry box insert MASTER, do the same for the second SPI Debugger, and insert SLAVE.

Connect both SPI debugger as shown below.(tip: right click on left-hand side SPI debugger and use "x-mirror" option )

Next, right-click on MASTER SPI Debugger and select "SPI Mode" to "MASTER".
Insert 1 in "Master clock frequency.
Type binary sequence in other properties entry box {SEQUENCE = 01010101B}equivalent to 55 in HEX.

Next, right-click on SLAVE SPI Debugger and select "SPI Mode" to "SLAVE".
Insert 1 in "Master clock frequency.
Type binary sequence in other properties entry box {SEQUENCE = 11111111B} equivalent to FF in decimal.

 Now, run the simulation, if everything goes fine both debugger terminals windows will be displayed and 8 bit will exchange between both terminals

tip: You can also open Terminal window from Debug

      Empty windows means user is not providing sequence in supported format.
      to avoid this problem you can be used a prefix to denote binary values (e.g 1101b).

PIC18F PINOUT

By
Vdd(Vcc) Two pins are used to provide supply voltage to the chip.The typical voltage source is +5V DC. Vss(GND) Two pins are also used to for ground. OSC1 & OSC2 The PIC18F has many options for the Clock source.Most often a quartz crystal controller is connected to input OSC1 & OSC2.The quartz crystal oscillator connected to the OSC1 & OSC2 pins also needs two capacitors.One side of each capacitor is connected to the the ground as shown in figure below: PIC18F microcontroller can have speeds of up to 40 MHz. Easy Programming  PICKIT3.5 PIC KIT3.5 PICKIT MCLR Pin1 (in the PIC18F4548 40-pin DIP) is the MCLR (master clear reset) pin. It is an input and is active-Low (normally High),When a low pulse is applied to this pin,the microcontroller will reset and terminate all activities.This is often referred to as a power-on reset (POR). Port A, B, C, D & E The Ports PORTA, PORTB, PORTC, PORTD, and PORTE use a total ...

PIC18f4580 Timer0 calculation using miKroC , CSS and proteus

By
PIC18f4580 TIMER PROGRAMMING The PIC18f4580 has four timers. they're named as Timers zero, one, two, and three. they will be used either as timers to come up with a time delay or as counters to count events happening outside the microcontroller. First, we see however Timers zero is employed to come up with time delays. Every timer wants a clock pulse to tick. The clock supply will be internal or external. If we have a tendency to use the inner clock supply, then 1/ fourth of the frequency of the crystal oscillator on the OSC1 and OSC2 pins (Fosc/4) is fed into the timer. Therefore, it's used for time delay generation and for that reason is termed a timer. By selecting the external clock choice, we have a tendency to feed pulses through one among the PIC18's pins: this is often known as a counter. GIF  taken from  https://exploreembedded.com Basic registers of the timer Majority of t timers in 18F are 16 bits wide. Because the PIC 18 has an 8- bit ...
