[Moved] SPI protocol using 2 PIC16f877a

[kgavionics]

hi guys i just want to share with you my last project.It concists of 2 pic16f877a communication using SPI.
The master microcontroller is executing a program that count from 0 to 255.
The second microcontroller which is a slave is receiving count with SPI protocol and displaying it on Lcd.
here's the video

pretty easy project, done with assembler.
hope you like this little project

Interesting but... it there any goal???

My goal is learning....is there any goal better that this????

For sure, it's a good way!
I don't know if you know the MAX3100, it's an SPI to RS232 transceiver. In the same way, you can send data via SPI and connect the device to your computer via the serial port (232). Then the data can be printed to your computer's screen. (or be used by a soft to plot some curves)
Otherwise, you can use a sensor (temperature, pressure...) and send data from the master to the slave and print it on your little screen. Your code is a good starting point for many applications!

Anyway, it's a nice video!

enjoy

merci Fabien
yes don't know the MAX3100,but i know only MAX232.
I took a look at the MAX3100 datasheet and it seems very interesting circuit.Thank you for the information Fabien

I am starting on this.
Please can you give me the code for the pics?
