How to use SPI Debugger

 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".

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
