Arduino Workshop - Chapter 5 - Using SPI

In this section, you'll learn how to use the SPI interface to send and receive serial data for interfacing with sensors and other devices.

Thanks for the video! A great intro to SPI. I had to modify the for-loop just a bit to get this to work on my ELEGOO UNO R3. I had to set "i=0". My LEDs would not toggle without this. So in full: "for (int i = 0; i < 256; i++) "

I had no idea that SPI could be used with shift registers. I couldn't get shiftOut to work and had to write my own library for shift registers to get it to work.

thanks God ! Your video saves my embedded software career

[dedesite]

Thank you for this video, it was really clear and help me a lot to understand the basics of SPI !

[navneetbrar]

Brilliant explanation..keep up the good work

[Nomnomnom]

Could I use a decoder to control the slave select outputs? Is there any reason I wouldn't be able to use this?

[mtalhakhalid]

I use spi to program at89s51 or 8051 another arduino or attiny85 micrcontroler

[saptarshiraut]

awesome series for beginners... thank you so much...

[yashesvii]

in every iteration of the for loop, will SPI.transfer(i); write the bin format of i on the same register every time? And please explain the breadboard too !? Thank you!

[johnsantos]

Sir great video, lots of intro, very little hands-on that is the only problem with the video... we care about all this intro we care more about connecting and extracting. Can you do that?

[matrixdexter]

can you show it with multiple devices. am stuck at beginner level

[ramiabdelmajid]

Hello, great course thanks for your effort but i haven’t found the SPI diagram. I only found the I2C diagram.

[jiteshsharma]

Please may I know the name of IC that you use on breadboard & resistor value also

[craigmunday]

Really nice introduction. Is there any cleanup code to execute to close down the SPI interface when no longer required?

[jiteshsharma]

@6:47 please let me know name of IC used on breadboard

[jiteshsharma]

@6:47 ...
Name of black IC that you have used on breadboard

[calvin-]

@6:30, can we change the number of bit to 10 bits to shift register?

[Sandipmaurya]

I want to communicate 16 bit data please help me

[almirbajsini]

im trying to control servo with potenciometer using spi (with hc12) i have no idea what you are talking about im loosing my mind 😂😂😂

Your sketch Arduino Workshop - Chapter 5 - Using SPI

I'll skip over your use of "Master and Slave". Inappropriate for more reasons than just politically correctness. Maybe main and deputy, or processor and widget?

Have never seen "for (int i; i < ...." before. Please change to 'for (int i = 0; i < ....'
I once declared an undefined variable as local integer. The first use was within an if() statement. Spent days trying to figure out why the sketch would only malfunction between 8 and 13 minutes after startup. This did not take as long. Even delaring int i = 0; as local for the loop() function, would not make 'for (i; i< ....' work
