Having compatibility is nice to have but as the family of features are most definitely growing what is to decided features to chop and what to keep just because of some silly format compatibility....

I am just curious Paul if you plan on using the i.MX RT1170 in the future. i see that the chip is unbelievable in many aspects compared to anything Arduino on the market except of course your...

Well since there was no response to the question about the 3.3 volt pins i did some investigating of my own and finally found on another thread. according to the schematic on the 4.0 (thanks Paul) it...

I get it now as it makes more sense from your description when i go through the code.
the only reason i was going to use LED's with the shift registers is if they work out that circuit and code is...

"/* This will give two identical outputs as start */
int shiftPos=1, shiftDir=-1;:

I do not understand what you mean by two identical outputs ? i am also confused as to print instead of SPI, can...

Here is the updated code using SPI shifted left then right. unfortunately there is no overlap so i might have to use the array example KurtE presented as that has overlap if i can not get the below...

KurtE ;
The code finally compiled but will changing the update period to a longer time will it effect the function of SPI.? i do need to visualize it's functioning properly.
i realized what you...

In function `main': C:\Program Files (x86)\Arduino\hardware\teensy\avr\cores\teensy4/main.cpp:51: undefined reference to `setup' C:\Program Files...

That would be a big 10-4, 64 bit variable. sorry i missed it.
...

Code would not compile, massive errors to many to list. the original code i posted does compile though.

KurtE;
Video's are not ment for you. thank you for your help. what about the original code i posted, it seems it is less complicated then an array.??? i do have to ask you can i slow this down...

Here is another very informative video please watch the whole thing.

this guy nails it very well.

Let me repeat,

You would be incorrect 595's can be shifted both directions so i only need 6 - 595's for 46 taps. many Youtube video's state this as a fact.Sorry !

KurtE;
Not sure what you mean about...

Unfortunately i am unable to figure out how to get the code to shift to left when it hits the last tap. i need it to shift right then left on a continuous basis.
sorry for the mistake on code above...

Hello all;

I am new to Arduino and especially SPI protocol and would be very thankful for any such help on my project.

what i am attempting to do is switch taps on an active inductor controller...

Thank you both for your replies.

mborgerson;

I have 6 shift registers in the circuit and the SCK goes to all 6 and not 34+ like in the link. out of respect for this thread i think i will start...

Hello i am new so please put the blade away.
i am a bit confused as to why on earth was the only SPI pinned on Tensy 4.0 saddled with an LED in the first place. i have a major project going that...
